The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the milland impact from the hardened steel balls and the rock itself. In order to ensure that the rock is ground finely enough the SAG mill has a trommel screen (5)which acts like a large sieve.

Oct 112019 Sulphide copper-gold ores are usually sorted by flotation. The standard comminution process to grind the ore to flotation finenessmostly consists of coarse crushing followed by SAG milling or wet ball mill circuitsor alternatively multiple stage crushing followed by rod and ball milling.
Over-grinding does not have a significant benefit to gold recovery but reduces the mill throughput and results in higher unit costs in terms of energygrinding media and reagent consumption. If there are frequent changes in ore hardnessgrinding circuit performance is affected and poses challenges for operators to maintain the target particle
South Africa - South Africa - Diamondsgoldand imperialist intervention (18701902): South Africa experienced a transformation between 1870when the diamond rush to Kimberley beganand 1902when the South African War ended.

For the mining industryour semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the goldcopper and platinum industries as well as in the leadzincsilverand nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
