Guillaume Daniel (G.D.) Delprat, after whom this shaft was named, was a Dutch-Australian metallurgist and mining engineer. An astute businessman, Delprat was Broken Hill Proprietry Limited’s ( BHP) General Manager from 1899 to 1921. He played an important part in the perfecting of a technique that came to be known as the (C.V.) Potter-Delprat flotation process; it revolutionized sulphide ore treatment and brought enormous profits from the metal content of millions of tons (tonnes) of formerly useless tailings.and a developer of the flotation process, which entails separating valuable minerals from gangue (mined rock that is not ore) with water.
The Delprat shaft was sunk in 1900. In 1952, the original wooden headframe was replaced by the present steel structure, and an electric winder replaced a steam engine. The early steam engines used to power mining machinery in the early twentieth century were powered by boilers fuelled by local firewood. Timber was also cut for use in buildings and headframes.
The shaft was closed to mining by the time MMM (Mining for Metal and Minerals) ceased operations in August 1976. It became a tourist mine in 1977, and its closure in 2007 was due to nearby remnant mining operations by CBH Resources.

Apart from their incredibly quiet rotor blade design seen here there's an abundance of detail visible on these Navy Merlin HC.4's
There's the 'cable cutters', one just ahead of the main rotor housing plus a pair under the nose along with another pair by the wiper motor housings - all designed to snag and cut any cables they might encounter accidentally when on low level missions
The green rectangle below the cockpit is part of the inflatable flotation system deployed in the event of a ditching and just below and behind that is a 'Chaff' and Flare safety device - both the latter are part of the system firing strips of foil (Chaff) or Flares used to deter heat seeking or radar guided missiles
Not sure what the box-like lump is just behind the forward entry door (possibly the Chaff and Flare dispenser?) but these were added when the HC.4's were 'Navalised' after their original RAF ownership
Other than that various hand and foot holds can be seen for access and maintenance purposes
There are also two small warning receivers fore and aft of those lower nose windows plus various added lumps and bumps under the forward belly and under the nose, the latter seems to be a standard fit (possibly a weather radar) across the HC.4 and 4A fleet of which these are.
The 4 is the ex RAF model and the 4A are the ones which were destined for the Royal Danish Air Force but were swapped on Yeovil's production line to replace RAF ones that we lost during the Afghanistan War
Those destined for Denmark had a double bump nose profile but the latter have since been removed and a new nose as here, standardised across the fleet
Along with folding rotors being added when the Navy acquired them, as can be seen on the extreme left-hand example, the tail now folds too for stowage aboard our Carriers and Ships that can operate these huge Merlin helicopters
These also differ from the Merlin HM.2 which the Navy operate in the Anti-Submarine and AEW roles in that they have a rear loading ramp and feature twin wheels all round whereas the HM.2 has no loading ramp and only a single wheel on each main leg

One of the many bites placed on a lizard that fell into his web. The blue background is a flotation toy for our pool where the spider anchored some of his web. The lizard must have fell from the fence where the floaty was leaning against.
IIRC, back then manufacturers of this type of vehicle were not required to include personal flotation devices. Like seat belts, personal flotation devices were extra-cost options.

Potash evaporation ponds at the Intrepid mine near Moab, Utah. I did not photoshop the ponds to produce an electric blue color. A blue dye is added to the water to absorb more light and enhance the evaporation process.
Most potash forms in arid regions when inland seas or lakes dry out. As the water evaporates, it leaves behind potassium salt deposits. Over geologic time, sediment buries these deposits and they become potash ore. The ore at Moabâwhich actually lies about 1,200 meters (3,900 feet) below the surface and within the Paradox Formationâbegan to form about 300 million years ago.
In Utah, the miners pump water deep underground to reach the potash ore. Potash is soluble, so water dissolves it into a brine. That brine gets pumped into underground caverns, where the potash continues to dissolve. Eventually, a highly-concentrated brine is pumped all the way to the surface and into one of the evaporation ponds shown above.
As the water evaporates, potash and other salts crystallize out. This evaporation process typically takes about 300 days. The water is dyed bright blue to reduce the amount of time it takes for the potash to crystallize; darker water absorbs more sunlight and heat. The crystals of potash and salt are then sent to a facility to be separated through a flotation process.
In 2013, the United States produced about 970,000 metric tons of potash, about two percent of global production. The fertilizer industry consumed about 85 percent of the potash produced by the United States; the chemical industry used the rest. About 60 percent of the U.S. potash was the muriate type produced at the Moab mine. Source: earthobservatory.nasa.gov/IOTD/view.php?id=83905
At the time (July 2008) QR National was owned by the Queensland Government, but strangely was allowed to compete for non traditional traffics against private rail operators under open access principles.
In New South Wales it progressively made inroads in the Hunter Valley coal traffics and today has about 20% of this particular market.
In 2010 the business was privatised through a stock market flotation and was renamed Aurizon.

FV180 CET (Combat Engineer Tractor) (1977-on) Engine 12,200cc Rolls-Royce C6TFR turbocharged diesel engine, developing 320 hp.
Dimensions Length 7.54m, Width 2.9m, Height 2.67m
Combat Weight 17.5 tonne
Road Speed 35mph (56 kh.h
First produced at the Royal Ordnance in Nottingham in 1977, the CET entered service from 1978, In 2013 the CET was withdrawn from service by the British Army.
The FV180 Combat Engineer Tractor or C.E.T. is an amphibious specialist armoured vehicle formerly used by the British Army. A tracked, lightly armoured vehicle, with amphibious capability, the CET was used by Royal Engineers in ground preparation for bridge construction and towing activities in the front line of battle, such as digging vehicle fighting pits, constructing earthen barriers, repairing roads, recovery of disabled vehicles from water and other obstacles, preparing riverbanks for vehicle crossings and clearing obstacles
Its two man crew sit in tandem positions on the left hand side of the vehicle, each with a set of driving controls facing opposite directions. A large earthmoving bucket is fitted at the rear of the vehicle and a rocket-propelled anchor on a 100m hawser attached to an 8 tonne winch can be fitted to the front. When operated from the rear seat the bucket is used for earth moving; clearing obstacles, paths or digging tank or gun pits and anti-tank ditches. When operated from the front-facing seat it can be driven on the road, and the anchor can be used to pull the CET up steep obstacles such as riverbanks.
The vehicle is NBC (Nuclear, Biological and Chemical) proofed and has an air filtration unit, supplying clean air to the crew when operating with the crew hatches closed down in a contaminated environment. The NBC air system is also used to inflate the buoyancy aids required to trim the vehicle when swimming.
The amphibious propulsion is provided by two Dowty water impellers, one mounted on each side of the vehicle and controlled by the commander in the rear seat facing forwards. The water jets are used to steer the vehicle when swimming, this is with the use of movable cowls directing the flow of water. When not in use, the propulsion unit water intakes are closed off with armoured covers to prevent damage during digging operations. Flotation aids are required to trim the vehicle for swimming
Maximum speed in water is 8.5 knots, the vehicle will wade in 1.8m of water and requires preparation for operating in deeper water than this as it achieves buoyancy. FV180 can tow a Giant Viper anti-mine system. is air-transportable weighing 17.5 tons by a C-130 Hercules aircraft.
In 2013 the CET was replaced in British service by a new, larger vehicle: the 30 tonne Terrier armoured digger. The CET is still used by Forces of India, Singapore and the Ukraine.

Still trying to come up with a solution for the front end of the floatation kit. Still a bit...ugly. :) Austin added clips with a Panzerfaust on both sides of our built RSO, so we added it to this one as well. :) We used PA's older RSO for the model. Was going to use curved pieces, but it worked out too big. So we stuck with this one. :)

These fortress-like stone foundations are the remains of Broken Hill Proprietary Limited (BHP)’s concentration mills that operated from 1894 to 1897. The company’s first concentration mill was built on the east side of the lode in 1889. Concentration is the process of separating valuable metals or minerals from the raw material, in this case ore. The first mill was closed due to subsidence.
A gravity mill with a capacity of 10,000 tons of ore per week was erected here in 1897. The mill produced high-grade lead, but millions of tons of zinc-rich waste product, or tailings, were dumped.
In 1904, the flotation process was added to the plant. Flotation involves crushing the ore to separate valuable minerals and gangue (mined rock that is not ore) components, pulping the particles of ore with water, and then separating the specific mineral. It operated until 1927 and was demolished in 1940.

There are several species known as cotton tree in Brazil, almost all belonging to the genus Ceiba (formerly Chorisia family Malvaceae (previously Bombacaceae)In all, the best known species is the cotton tree Ceiba speciosa (St.-Hill.) Ravenna, native forests of Brazil and Bolivia, initially described as Chorisia speciosa St. Hilaire 1828.FEATURES: -It is a tree with up to twenty feet tall, gray-green stem with grooves and photosynthetic strong blunt spines, very sharp in the younger branches.The trunk of Painswick has a good ability to synthesize chlorophyll (photosynthesis) and greenish to have when you have a good size, that helps growth even when the tree is bare of leaves, is also common Paineiras present a kind of enlargement on base of the stem, hence the nickname "paunchy". Detail of the trunk, with photosynthetic tissues (photographed in Portugal)The leaves are composed slaps and fall during flowering. The flowers are large, with five pink petals with red spots and white edges. There are a variety of less common, with white flowers. Paineira-white, less common variety, with white flowers in the park Ceret, in Sao Paulo, Brazil Their reproductive organs are united in a long androginóforo.The fruits are green capsules which, when ripe, burst (dehiscent), exposing the seeds wrapped in fine white fibers that aid in flotation and which are called kapok. From twenty years old, approximately (southeastern Brazil), the spines usually start to fall in the lower stem and gradually also fall in the higher parts of the tree, with thickening of the shell. It is said, in Brazil, this allows the tree to get birds' nests, which would be impossible to happen when it had long, sharp thorns, so flowers and fruits are no longer present, but the tree continues to give its contribution to Nature hosting the birds. This is not a rule for all Painswick, Painswick some with more than twenty meters, for example, still have very large thorns on the lower, probably as a defense of the local insects.
Há várias espécies conhecidas como paineira no Brasil, quase todas pertencendo ao gênero Ceiba (antes, Chorisia da família Malvaceae (antes, Bombacaceae)
De todas, a mais conhecida é a paineira da espécie Ceiba speciosa (St.-Hill.) Ravenna, nativa das florestas brasileiras e da Bolívia, inicialmente descrita como Chorisia speciosa St. Hilaire 1828.
CARACTERÍSTICAS:-
É uma árvore com até vinte metros de altura, tronco cinzento-esverdeado com estrias fotossintéticas e fortes acúleos rombudos, muito afiados nos ramos mais jovens.
O tronco das paineiras tem boa capacidade de sintetizar clorofila (fazer fotossíntese) e tem coloração esverdeada até quando tem um bom porte; isto auxilia o crescimento mesmo quando a árvore está despida de folhas; é comum, também, paineiras apresentarem uma espécie de alargamento na base do caule, daí o apelido "barriguda".
Detalhe do tronco, com tecidos fotossintéticos (fotografada em Portugal)
As folhas são compostas palmadas e caem na época da floração. As flores são grandes, com cinco pétalas rosadas com pintas vermelhas e bordas brancas. Há uma variedade menos comum, com flores brancas.
Paineira-branca, variedade menos comum, com flores brancas, no parque Ceret, em São Paulo, no Brasil
Seus órgãos reprodutivos encontram-se unidos em um longo androginóforo.
Os frutos são cápsulas verdes, que, quando maduras, rebentam (deiscentes), expondo as sementes envoltas em fibras finas e brancas que auxiliam na flutuação e que são chamadas paina.
A partir dos vinte anos de idade, aproximadamente (sudeste brasileiro), os espinhos costumam começar a cair na parte baixa do caule e, gradualmente, também caem nas partes mais altas da árvore, com o engrossamento da casca. Diz-se, no Brasil, que isto permite à árvore receber ninhos de pássaros, o que seria impossível de acontecer quando esta tinha espinhos longos e pontiagudos; assim, flores e frutos já não estão presentes, mas a árvore continua a dar sua contribuição à natureza hospedando os passarinhos. Esta não é uma regra para todas as paineiras; algumas paineiras com mais de vinte metros, por exemplo, continuam com espinhos muito grandes na parte baixa, provavelmente como defesa de insetos do local.

Lowest Point
The Dead Sea is located in the Syro-African Rift, a 4000-mile fault line in the earth’s crust. The lowest point of dry land on earth is the shoreline of the Dead Sea at 1300 feet below sea level. That the lake is at the lowest point means that water does not drain from this lake. Daily 7 million tons of water evaporate but the minerals remain, causing the salt content to increase. Figures for the Dead Sea’s salinity today range from 26-35%.
Mineral-Rich
Nearly ten times as salty as the world’s oceans and twice as saline as the Great Salt Lake in Utah, the Dead Sea is rich with minerals. The Dead Sea Works company on the southwest side of the lake employs 1600 people around the clock to harvest the valuable minerals from the water. Potash is the most valuable of those extracted today and is used in the manufacture of fertilizer.
Evening sun shines on the face of CSX SD40-2 8368 as she powers rail dropper W362 on the shove through Flotation en route to Toe River to tie down for the day. This train started its day dropping rail along the Clinchfield Loops and worked its way up over the mountain to round out at Beaver Creek Curve in Spruce Pine. The Boxcar-less "CSX" logo, cab mounted headlight, and matching EMD Font Number Boards still make this old C&O gal gorgeous... and are features that are becoming increasingly harder to catch.

Harbour Fishing boat reflection. A bright morning sun and a very light wind on a very colourful local fishing boat.
Knowing what swims in many of the waters of Florida, I don't really think a canoe is the best option for flotation, but a lot of people do like them and canoe rentals flourish during the warm seasons.
Here at DeLeon Springs, you seldom hear about gator encounters. A couple of years back, though, a man who regularly swam in the waters of Blue Springs nearby disappeared, and was found to have been the victim of an alligator attack. The 12 foot gator was killed when the man's body was recovered. An alligator would have no problem tipping a boat this size, since they are often much larger than the boats floating around them! I will choose to stay on shore in Florida's natural habitat, and even at that, staying away from the water's edge is a good thing, too. Gator's are ambush predators and lie in wait watching from the bottom of lakes and ponds. You can't see them, but they definitely can see you!

El nom de la font prové del fet que al seu voltant, prop del riu, s’hi fabricaven cordes indispensables per a dur a terme les feines del camp.
El darrer corder que va utilitzar aquest espai, fins al 1936, estava establert al carrer València, 59 (Cal Corder). Probablement era l’última font abans d’abandonar el casc urbà, i un espai on també es rentava la roba en el safareig públic.
(Informació copiada del mateix lloc).
La part verda de la imatge está formada per llentilles d'aigua o llenties d'aigua (Lemna minor) que floten a la superfície de l’aigua.
CATALÀ
Quan l’aigua de la font cau a la pica es formen aquestes bombolles i alhora s’hi veu… “llentilla d'aigua o llentia d'aigua (Lemna minor) és una espècie de planta aquàtica del gènere Lemna la qual té una distribució subcosmopolita… Disposa d'una, dues o tres fulles amb una arrel, d'1 a 2 cm, que penja a l'aigua. Quan creixen més fulles, la planta es divideix en individus separats. Les fulles són de forma oval d'1-8 mm de llarg i 0,6-5 mm d'ample, de color verd clar amb tres (rarament cinc) nervis i espais petits que ajuden a la flotació.”

Cordera Fountain
The name of this fountain comes from the fact that around it, near the river, ropes (cordes) were manufacture. These were vital for agricultural tasks.
The last ropemaker is (“corder” in Catalan) that used this space ran his business at 59 València Street (Corder House) until 1936. It was probably the last fountain found leaving the town centre; furthermore, this area was used as public washing place where clothes would be washed.
(Information copied from the same site).
The green part of the image is made up of Lemna minor, the common duckweed or lesser duckweed floating on water surfaces.
ENGLISH
When the water from the spring falls into the sink, appear these bubbles and at the same time we see…”Lemna minor, the common duckweed[2][3] or lesser duckweed, is a species of aquatic freshwater plant in the subfamily Lemnoideae of the arum family Araceae... Lemna minor is a floating freshwater aquatic plant, with one, two, three or four leaves each having a single root hanging in the water. As more leaves grow, the plants divide and become separate individuals. The root is 1–2 cm long. Leaves are oval, 1–8 mm long and 0.6–5 mm broad, light green, with three (rarely five) veins and small air spaces to assist flotation. It reproduces mainly vegetatively by division. Flowers are rarely produced and measure about 1 mm in diameter, with a cup-shaped membranous scale containing a single ovule and two stamens.”

Fuente de la Cordera
El nombre de la Fuente procede del hecho que a su alrededor, cerca del río, se fabricaban cuerdas, indispensables para realizar las tareas agrícolas.
El último cordelero que utilizó este espacio, hasta 1936, estaba estabecido en la calle Valencia, 59 (Casa Corder). Se trataba, probablemente, de la última fuente antes de salir del casco urbano; además era un lugar usado como lavadero público donde se lavaba ropa.
(Información copiada del mismo lugar).
La parte verde de la imagen está formada por lentejas de agua común o lentejas de agua menor (Lemna minor) que flotan en la superficie del agua.

Cuando el agua de la fuente cae en la pila se forman estas burbujas y al mismo tiempo se vemos …"La lenteja de agua común o lenteja de agua menor (Lemna minor) es una planta acuática pequeña, perteneciente a la familia de las aráceas. Es una planta acuática pequeña, esta es la más conocida de las especies de lenteja de agua. Sus hojas flotantes son oblongas, con 3 nervios destacados. Se sumerge para florecer. Especie casi cosmopolita. Crece con tanta rapidez y eficiencia que puede provocar grandes daños, como es el caso del Lago de Maracaibo, que aprovecha los fertilizantes residuales de las plantaciones colindantes para su crecimiento de forma incontrolada. Desde su aparición, el problema ha ido aumentando progresivamente, pudiéndose medir en las últimas observaciones más de 136.000 ha de Lemna.”

All in a days work.....
The 1882 Gilmer and Salisbury concentrating mill is the dominant structure at Bayhorse. Its iconic shape and mass is symbolic of western mining camps. Built on a hill side to take advantage of gravity, raw ore entered the upper portion to begin a process of crushing and separating valuable minuerals from waste rock. After an initial crushing to storage bins, the ore passed through the stamp mill, then sluice boxes and settling tanks, and on to the concentrating tables, mechanical shaking tables, called "Frue Vanners". Once the ore was concentrated it was delivered to the smelter for reduction. Except for the ore operation. In the 1920s, the mill was remodeled as part of the change in operation to a flotation method of ore recovery. The stamps were removed, more efficient crushing equipment installed, and settling tanks added. The concentrated ore was dried and classified (graded), and then shipped to a smelter for recovery and refining. (info from a sign on display at this building.)
This poor old abandoned mine was my first attempt at using lens correction in photoshop. I also tried using the automatic HDR toning to try and bring out more color in the wood. This was also the building that the previous image (DANGER) was on. Needless to say, we didn't go in.
“The one thing I remember about Christmas was that my father used to take me out in a boat about ten miles offshore on Christmas Day, and I used to have to swim back. Extraordinary. It was a ritual.
Mind you, that wasn't the hard part. The difficult bit was getting out of the sack.”
― John Cleese
The Block 10 mine, one of the original BHP leases, was floated as the BHP Block 10 Co. Ltd in 1888. A concentration mill was erected at the mine in the 1890s to treat sulphide ore. Underground subsidence seriously affected the mill and, as a result, a new mill was erected on this hill in 1903, about 600 metres from the mine.
An aerial ropeway, the first at Broken Hill, was completed in 1904. This transported broken ore from the mine to a large storage bin above the mill. The mill cost £50 000 and could treat 3500 tons of ore per week.
The mine produced 2.5 million tons of ore and paid £1.5 million in dividends up to 1923 when it and the mill closed and were purchased by BHP. The mine was reworked by Broken Hill South Ltd between 1946 and 1960. Much of the mine site is now covered by overburden dumps from modern open-cut operations.
The concrete foundations on site are the remnants of the Block 10 concentration mill erected in 1903. The mill, designed by Captain John Warren and containing many of his inventions, was the first all electric mill in Broken Hill.
The aerial ropeway delivered broken ore from the mine to a storage bin above the mill. Broken ore was fed to crushing rolls and then passed to cylindrical trommels and hydraulic classifiers for sizing. Subsequent treatment consisted of wet concentration by jigs, Wilfley tables and vanners. These relied on specific gravity to separate the heavier lead and silver minerals from the zinc minerals. The resultant concentrate contained about two-thirds of the lead and one-half of the silver in the original ore, but very little zinc.
Flotation units were added to the mill in 1910 to produce a zinc concentrate from the tailings. Combined gravity-flotation concentration mills were standard at Broken Hill until after 1930 when the first all-flotation plants were installed.
