These machines circulated water through the powder from the ball mills. Gold and silver is heavier than gravel, so it sinks while the junk rock floats.
The right-pointing crank adjusts the rollers inside of the mill. How fine do you want your flour?
These machines are at least 100 years old.
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.
From the catwalks below the hoisting motor in Shaft No. 1.
Inside the pilot copper concentrator.
When the building switched souls from booze to bread, these contraptions were mounted across the brewhouse floors… they’re not for hops, either.
The top of the docks are so rotten in places that you can see the lake through the boards. In the foreground you can see the controls for the chutes, which work on a clutch.
A wounded flour mill, muscled into the corner to keep out of the way.
The aft lifeboat survived auction, although now all it holds is an emergency ladder to help men who’ve fallen overboard get on deck.
Scrappers tried to take this steel pulley out of Fisher, but it proved too heavy.
Beautiful belt wheels above the grain cribs. Getting to the spot where this was taken is now impossible, and I don’t know whether these remain or not anymore.
On the upper floors where the sunlight is yellow–the color of flour dust, once exposed to the elements.
I tried to hide the graffiti from my photos, but sometimes it wasn’t possible.
I wonder how sheltered workers on this mid-level catwalk that follows the ore chutes is in storms. Note the chunks of concrete stuck in the catwalk grates–the pockets (right) are falling apart.
On the National Mine property are two shafts, both serving the same workings. This one seems to have gotten some upgrades in the 1960s, judging from the condition of the metal.
The top of the headframe, and in a sense, the mine itself. This pulley carried the life line of the mine and the men in it.
An experimental shaft dug in the 1950s and its Hoist House.
A side view of the floatation level. I found it interesting that there were little ladders and staircases in the mill to help workers get around–this place was not as shoddy as other mills I’ve seen.
The belts on these mills have long ben missing.
David Aho, the owner of Mitchell Engine House, poses beside the boiler.
An unshielded heaframe and single pulley.
At the top of the Head Frame, over the silo, a space is hollowed-out for ore cars to dump their load before going back underground in search of copper.
