Ore Mill (Lebanon Mine CO)
This mill (left building) measured only 30 by 60 feet was patented in 1872 by Julius G. Pohle, Superintendent of the Lebanon Mining Company. The two-story wood frame structure contained machinery driven by a horizontal water wheel, and the mill dam spanned Clear Creek. Good wagon roads lead to it from all the mines on the Leavenworth, Republican and Sherman mountains
The chief purpose of the mill was to dress, concentrate, and sample the ores from the mine. Dress means to clean or remove waste rock (called gangue) from ore bearing rock. Concentrate means to separate ore from its containing rock. Sample is the process of taking a portion of the ore to represent the entire bulk of ore. This was important because the Lebanon Mine often was digging in more than on vein at once. Different veins often had different proportions of silver content compared to waste rock.
