Extracting Gold HowStuffWorks

To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In these drums, the ore is ground to a fine slurry or ...

What Is Involved in Phosphate Mining? (with pictures)

11/02/2021  The specific processes used to extract phosphate rock depend on the geographic characteristics of the area in which the mineral deposits are located. Most phosphate mining is conducted as open-pit mining rather than subsurface mining. In a typical mining operation, a layer of topsoil and other material is removed and placed into already-mined areas. Large dragline excavators then extract

A process for reducing rocks and concentrating heavy

To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80- to 270-mesh (an opening between wires in a sieve). The openings in an 80-mesh sieve are equal to 0.007 inches, 0.177 ...
