Collection Kimmerle, Myrna J. Nielson
Photo Number 5051.3
Description Kimmerle Mill: the ball mill, just after it was set. The size of the engine (at right) is very small in comparison to the grinding mill. According to Leland Shumway, "Above is the ball mill. It crushes the ore into fine sand, then the ore is mixed with salt and run through a large roaster at high heat, and then drops into large tanks of water and sulfuric acid." (See photo 5051.4)
