Feb 29, 2016 Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit. To quantify recovery is a reasonable idea of the initial ore required to have an economical operation. In this part, a reliable sampling representing the ore is a key aspect
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
