Kate for scale. Powder that passed the floatation level was flowed over sluice tables, another mass-based way of separating gold. I’ve never seen so many of these in one place. Though it was a hardrock mine, it worked more like a placer mine.
Around the corner from the old boiler room.
After crushing, these machines would float lighter material to the surface of the water, where it would be skimmed and discarded. Gold and silver laden stone would sink to the bottom, where it was collected for the next stage of processing. Leica/Summilux 35/Ektar 100
A typical lab at the Research Center.
This big rusty sphere hides behind the incomplete 5-stack.
This gives a sense of the scale and the water damage of the old side (brick, rather than concrete) of the roundhouse.
On the Turbine Room floor, one old steam pump still remains, ready to pressurize steam pipes with the hot stuff throughout the car shops and boilers.
One of the pair of motors that powered this mine shaft. In the 1950s, this shaft was designated a rescue shaft, and was only maintained for emergencies. One reason that Cheratte built Shaft 3 nearby was because these motors and infrastructure did not have the capacity that the giant mine below called for.
A screened water wheel, presumably for rotating the dredge once it lowered its “foot” to pivot in place.
