Publisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.

The above pretreatment stages can be changed based on ore mineralogy. For a complex AuAg ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µ leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test results, extraction strategies for gold ...

Refractory gold ores are classified as if a cyanidation process cannot recover more than 80% of gold even though fine grinding is used (Guay, 1981). The reason for the refractoriness of gold ores is either because gold is hosted in solid solution, or as colloidal particles, in pyrite and/or arsenopyrite.

SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.

Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are relatively straightforward.

The grinding tests were run for different time intervals (1, 2, 4 and 8 min). After each interval, the whole mill charge was discharged and a representative sample taken for sieve analysis. Later, the material retained on the sieves were recombined with the rest of the mill discharge as feed for the next grinding interval.
