This might have been part of the Pioneer Pellet Plant. It looks to be a ball mill, which pulverizes ore by spinning it with thousands of ball bearings.
No wonder the factory shut down; everyone was scheduled to work 9 to 5 and the clock’s broken! (In all seriousness, this is/used to be a beautiful timepiece, especially for a utilitarian factory like this.
Before there was a row of double rooms on the left and a common room on the right. Now, in a way, it is all one big common room.
On the top floor of one of the old wards, the slanted roofline makes the this group room more claustrophobic. Portra 160.
I made this picture to give the reader a sense of the slope between the mine buildings and the base of the concentrator. The whole area was really steep, and sometimes required scrambling to get up and down the Picayune Gulch for short distances.
A closeup of the now-scrapped steel chute.
Scrappers infamously gutted the factory, but this one green conduit going from the sintering floor all the way to ground level seems to have been spared.
The basement of the laboratories is the home of the ore grinder. I’m sure it was noisy.
The buildings were level with one another, so one could look through as many as a dozen factory floors from one window.
