one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly ...

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises ...

process has caused many plants to dispense with gravity concentration, although they tacitly use longer residence times inthe cyanide solu-tion to compensate for the lack of concentration. Doff and Bosqui3 emphasize the importance of the early removal of gold from the milling circuit and advocate gravity concentration, especially for those
