GOLD AND SILVER

The extracted ore must be mill ed to prepare it for further recovery activities. Uniformly sized particles may be obtained by crushing, grinding, and wet or dry classification. The degree of milling performed on the ore depends on the gold concentration of the ore, mineralogy and hardness of the ore, the mill's capacity, and the next planned

Milling Crushing typically takes Run-of-Mine (ROM) ore down to particle sizes ranging from 6mm to 25mm, depending on the type of processes to follow. Crushed ore is fed into Mills in which the ore is mixed with water and may be ground down to a particle size, in the case of gold and copper, of about 75 microns (0.075mm).
