The hoist signal dangling beside the modern mine shaft would ring a bell next to the giant electric motors that would send the men and machinery into the underground.
Pipes to channel nitrose (think nitro glycerine) infused acid through the building.
Short-stack remains of mounts for rod and ball mills, if I was to bet. The concentrator separated junk rock (tails) from the copper and silver ore, to such a point it could be smelted.
Either the company was pulling parts from this evaporator to use as parts for other plants, or the last thing the workers did was to get this machine ready for the next campaign. Either way, plans changed.
This machine was last overhauled in February 1955, and last turned out Crepe silk, probably dress material.
The side of a launcher, with outbuildings in the background. You can see the tracks where the roof would open before launch.
Behind the evaporators are heavy access hatches to inspect the steam pipes within.
Where equipment was scrapped.
Giant paint mixers.
Some of the ruins are way off the beaten path… foundations of tank stands and pillars of buildings that never had walls or roofs.
The left wall is stacked high with wooden crates holding spools. Tags hang on machines describing the last batch of silk the mill ever produced.
A closeup of a soon-to-be-scrapped crane pulley.
In the upper left of the image you can see where the gas tanks used to be, along with the concentration equipment. Along the bottom you can also see some of the many railroad tracks coming and going from the plant–the ones visible here were incoming tracks that carried in hard coal from the eastern US.
Captured bolts for a pressure cooker on an industrial scale.
Shadows of the skylights form a backdrop for rust-welded machines.
This wheel scoops the washings from the sluice room and places it on the tailings conveyor.
In what has turned into a kind of industrial courtyard between four ovens some people have posted their tags. X was here.
The perimeter fence still holds strong, 50 years after it was put up.
Next to the generator room is the pump room, which moved steam around the complex.
In the mid-2000s, Peavey sealed the spaces between their Electric Steel Elevator bins. What they unwittingly created was a graffiti time capsule. “Impeach Bush”.
Thick glass windows allow workers to check the beet juice levels in this steel tank. You can tell by the reinforcement that it had a lot of liquid and had to hold against immense pressure. Kodak Tri-X 400/Leica M7.
The steam-powered hoist that pulled ore and dropped men from the mine. Note the hydraulic-operated brake on top with its massive brake pad. Now scrapped.
The end of one of the scrapped turbines. Judging by the aborted attempt at cutting it in half, the scrappers had some trouble with this one.
Latin; to grow. Root of the English word ‘surge’.
A colorful boiler is a happy boiler! RotoGrate systems remove ashes from the boiler firebox by revolving the bottom of the system to let the fly ash drop into a hopper. This greatly increases boiler efficiency.
Was the last job of this hook to lift the remaining equipment out of the hoist hall? The control boards, giant electric motors and transformers?
