Elements specific to gold ore processes, such as dry grinding for roasting operations, security considerations for gold milling, reagent additions, and integration of mineral processing steps in the comminution circuit, are also addressed.The mined ore is processed through a conventional semi-autogenous grinding and ball milling, including a recycle crusher, (SABC) comminution and carbon-in-leach (CIL) circuit together with a gravity gold recovery step with final residue reporting to a tailings storage facility by way of cyclone deposition.

Comminution - Wikipedia

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.The Coalition for Energy Efficient Comminution (CEEC) has been established and is supported by a broad range of mining sector companies keen to accelerate awareness, knowledge transfer and, by implication, improve energy and cost outcomes in the substantive area of comminution.
