This is one of the Adrena mining bees, of which there are 67 species in the UK. This one is quite worn and tatty but could be a female Adrena fucata (Painted Mining Bee). Taken at Bowlees Quarry in the North Pennines AONB
Hay más de 200 retros ilegals en el Sur de Bolívar trabajando en la minería.
There are more than 200 illegal backhoes working in illegal mining in southern Bolívar .
I've posted pictures of this kind of thing before, but the power of hydraulics still gets me every time. In this case what you're looking at are the two hydraulic rams which are used to lift the "box" of the mining truck to dump the material out. Each of the two rams is approximately the same thickness as my thigh and tapers down to about the same thickness as my lower leg. Maybe this doesn't blow your mind, but imagine holding up 150-200 tons of material with just your legs. Compare this to the rams on the CAT 793 haul trucks I posted about before which are about the thickness of my chest and carry around 240 tons nominal.
Protest rally called by Mining Dependents at Kranti Circle, KTC Panaji on 19.3.18. Supreme Court stopped all mining activities effective 16.3.18 after cancelling all mining permits. Protestors blocked traffic from both bridges and other entry points to the city. As a last resort, protestors were Lathi charged around 3pm. Maskot bracelet gold Video youtu.be/CzaV1Hyr8Us
This is a fun place to photograph. Amazing old buildings and old mining equipment. You can even pan for gold!

A coal tipple is a structure used for loading coal into railroad cars. You can take an interpretive walk around this old Coal Tipple.
Broken Hill is located east of the Simpson Desert in Australia. Silver, lead and zinc were discovered here in vast reserves in the 19th Century and it has been a huge mining centre ever since. The entire city is dominated by mining, mining history, and the legacy of wealth resulting in fine monumental stone buildings in an unlikely desert setting.
Bakestonedale Moor above Pott Shrigley has seen an extensive coal mining industry over the past 2-300 years. The last coal and fireclay extraction took place in the mid 1960's before the Peak Park planners put a stop to it. The nineteenth century workings left a number of deep shafts which remained open until the 1970's when they were capped by the then National Coal Board leaving distinctive concrete obelisks on the shaft top.
By 1864 Hite's Cove was a small community of 100 people, a hotel, two saloons, and a Chinatown, as well as a post office. It also had a 10-stamp, then a 20-stamp mill.
This area is filled with old mining equipment, perhaps dating to the stamp mills or even beforehand. This looks like it may have been a Knight Wheel, perhaps turning the stamps.

This mining exploration camp is located in the Kiniskan Lake area of Northwestern British Columbia. Mostly a lot of drilling was taking place when we went to conduct water sampling for this project. August 5, 2006.

The town of Butte, Montana (pronounced “byoot”) is known as the “Richest Hill on Earth” and "The Mining City". The Butte Mining District has produced gold, silver, copper, molybdenum, manganese, and other metals.
The area's bedrock consists of the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is part of the Boulder Batholith. The Butte Quartz Monzonite ("BQM") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous. BQM rocks have been intruded and altered by hydrothermal veins containing valuable metallic minerals - principally sulfides. The copper mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene). In the supergene enrichment zone of the area, the original sulfide mineralogy has been altered.
Seen here is the Continental Mine, also known as the Continental Pit. It is the only active mine in modern Butte. Mining here was started in 1980 by the Anaconda Copper Mining Company - it is currently owned by Montana Resources. The mine is situated on the eastern side of the Continental Fault, a major Basin & Range normal fault in the Butte area with about 3500 feet of offset. Over 100 different copper minerals are known from Butte to the west of the fault - many are minor minerals. East of the fault, lower grade rocks are present. The Continental Mine targets this low-grade deposit, which consists of disseminated copper sulfides plus copper- and molybdenum-bearing hydrothermal veins that intrude the BQM. Minerals include chalcopyrite, molybdenite, malachite, azurite, and cuprite. A secondary biotite mica halo is present around the deposit - the biotite is derived from hornblende amphibole.
Copper and molybdenum concentrates are produced at the Continental Mine, but they are not smelted locally and not even smelted in America. Concentrates are sold around the world, where material is smelted and the metals are produced. America shipping rocks overseas and buying back the finished product is the behavior of an underdeveloped country - America is not interested in smelting anymore - a sad reality.
When I visited in 2010, the Continental Mine was making 50,000 to 52,000 tons of ore each day. This mine can operate down to an ore grade of 0.1% copper. Most of the mineralization is disseminated copper, but veins are also present. Two stages of mineralization occurred in the Butte area - a porphyry copper system and a main stage system with large veins. The bottom of the porphyry copper system is ~ less than 12,800 feet below the surface. Veins peter out at 5600 to 5800 feet below the surface. At the Continental Mine, veins are small - they're veinlets less than 6 inches wide.
Mining is done 24 hours a day, 365 to 366 days per year. There's 1 to 2 days of down time at the mill. During those days, mining stops and waste material is moved. The ore:waste ratio is 8:10 (= strip ratio). The alluvial overburden consists of 7 paleosol horizons, including some caliches - the lime content results in an average pH of 8. The caliche material can be used to treat acidic materials.
"An ore deposit is a mine if it can stand total mismanagement and still make money."
Navadaville area where once bout 4000 people were here for the gold now just as few live here but area's as this still stand - it's where they used the rocks to level the ground to build there home's on.
