These are usually installed in the mill discharge cyclone feed or the cyclone underflow streams where a fraction typically 10 40% of the stream is treated by the gravity circuit The key factors affecting gravity recovery of gold from within grinding circuits are the …

It is then shipped to mills where it is first combined with water and ground into smaller chunks The resulting mixture is then further ground in a ball mill—a rotating cylindrical vessel that uses steel balls to pulverize the ore Separating the gold from the ore 4 The gold is then separated from the ore using one of …

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on the ore is not weighed and only assays will be available However it is possible to express the ratio of concentration in terms of ore assays

Coarse Gold It may seem trite to point this out but coarse gold does not remain coarse after experiencing many trips through a grinding mill Researchers have found that during milling gold is actually smeared onto other particles and flattened into shapes likely to report to cyclone overflow upon discharge
