21) Chemical storage
Format:
Image
Lime, soda ash and copper sulfate (used in the zinc ore processing) stored beneath the mill at Gilman. Tracks used by timber trucks and ore cars run down the center of the picture. [Same as 2007.008.123]
22) Ore conveyor
Format:
Image
A mine ore conveyor being loaded from another level down a chute that had chains for filtering out large rocks. A miner stood near the conveyor and picked out pieces of wood and other debris.

Steam control valves at the mill in Belden. These were located between the dryer and the loading tippel.
24) Steam controls
Format:
Image
Steam room controls located between the dryer building and loading tippel at Belden.
25) Mucking machine
Format:
Image
Air operated mucking machine preparing to load material. The scoop would go over the mucking machine and empty the ore into the cart behind. Operator controls were at the left side of the machine.
Format:
Image
Closeup of the flume used to dump "muck' onto the conveyor. This conveyor carried the ore to a series of crushing machines. Conveyors were used extensively in the mine. [related to photo 2007.008.090]
Format:
Image
Lead flotation cell separating the lead from the crushed rock. Lead and gold were removed from the muck before the zinc was separated.
29) Cyanide mixing
Format:
Image
Cyanide mixing machine in the mine at Gilman. Cyanide was shipped to the mine in 50 gallon drums and required the use of rubber gloves in handling.
Format:
Image
The cyanide injecting machine inside the mill at Gilman. Cyanide was used to clean the ore for processing. A pressure gauge is seen at the top of the injectors.
Format:
Image
Flotation area for the zinc ore. Water valves are shown at the bottom of the table.
33) Flotation area
Format:
Image
Floation area for the zinc ore at Gilman. Flotation tables were used to seperate the zinc and lead from the waste in the mining process. Further processing separated the lead and the zinc.
Format:
Image
Flotation stations in the zinc section of the mill at Gilman. The flotation stations were part of the process of refining the zinc ore.
35) New zinc dryer
Format:
Image
Quinton Sagrillo performing maintenance on the new zinc dryer. Sagrillo was a dryer operator for New Jersey Zinc.
Sagrillo served in World War I and then lived in Telluride and Denver. He and his wife Rose then managed the State Agricultural Farm Experiment Station at Avon for four years. He accepted employment with New Jersey Zinc, working there for 20 years before retiring in 1959.

38) Mucking machine
Format:
Image
A compressed air-driven mucking machine at Gilman. The bucket has just been dumped into the ore car behind and is preparing to recover and pick up another load of ore.
Format:
Image
The rod and ball mill. The rod mill is on the left and ball mill on the right. These were used to grind the zinc concentrates for additional chemical processing. Prior to this, the material had chemical agents added to allow the zinc mineral surface to adhere to flotation bubbles. These were some of the steps for making the zinc ready to ship in railroad cars.
