The processing of gold ores has traditionally made use of conventional crushing and grinding circuits In each case where gold is formed either as coarse native particles or in coarse grained sulphides it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching

Gold mining is the process of mining gold ores from the ground up till the stage where pure gold is extracted Richiewiki 2010 The gold ores are usually big and have to be crushed to reduce them to a size of about 12mm diameter before pure gold can be extracted from them The ore usually has to pass various crushing stages each reducing the ore to a certain size

The large talc rocks will be fed into crushing plant for small particles Then the talc ores will be sorted according to their talc content and brightness From talc rock to talc powder the talc processing plant involves crushing washing sorting analysis milling grinding pulverizing and packing etc

In most instances visible gold can not be seen under microscopic examination of pyrite gold ores However if the ore is ground to 200 mesh most times a few specs of gold can be visibly seen under microscopic examination Based upon numerous case studies it appears that gold particles in pyrite are generally fine ranging from 75 microns
