South Deep's milling circuit consists of a single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball mills. These mills are essentially rotating drums that have steel balls inside which grind the rock into particles that are finer than 0.075mm in size.

— Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.
2.1, Adopting The vertical spiral stirred mill to grinding the gold ore, and the same time leaching operation, can extract gold economically with low cost and high gold recovery. 2.2, Applied for the second stage ore grinding, the fine grinding of sulphide ore and the tailings recycling, could economically grind ore to -400 mesh more than 90%-95.
By embracing energy-saving ball mills, mineral processing facilities can enhance productivity, reduce environmental impact, and pave the way towards a more sustainable future.
Ball Mill Working Principle High energy ball milling is a type of powder grinding mill used to grind ores and other materials to 25 mesh or extremely fine powders, mainly used in the mineral processing industry, both in open or closed circuits. Ball milling is a grinding method that reduces the product into a controlled final grind and a uniform size, usually, …
Dolomite is a carbonate mineral consisting of calcium magnesium carbonate. It was first described as the 'stinking stone' by Belsazar Hacquet, an Austrian naturalist. Later, Déodat Gratet de Dolomieu, a French naturalist and geologist described it as a rock from the Dolomite Alps in Italy.
