84) 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.

Bob Radabaugh, mine geologist, at the Gilman Mine. The geologists determined areas of optimum ore yield through various methods of inquiry. Bob is shown with one of the low tech methods, the rock hammer, checking the rock formation.
86) Drilling
Format:
Image
Drilling prior to adding dynamite to blast a section for mining at Gilman. Protective clothing was worn to keep the driller from being injured by debris, but we see no eye safety wear.

H. Lee Ferris is shown oiling, checking and adjusting landing chairs at #1 shaft. These landing chairs are safety devices that fall into a blocking postion under the floor of the cage when it reaches the top of the shaft. These devices are on the sides of the shaft and prevent the cage from descending into the shaft until such time as the landing chairs are released manually. Mr. Ferris is standing in the cage which has been lowered to a point...

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.
