Ore sorting is a preconcentration process that improves the head grade of the feed to the concentrator. Separating out gangue and low-grade ore at the earliest opportunity optimizes downstream processing. Successful ore sorting also reduces variability in the feed, and delivers more value to the concentrator on an hourly basis.

The upper limit of the ore particle size is related to the ore size, embedding characteristics, and equipment size. In usually, the ore is 50-150mm, and the coal is 300-500mm. DMS can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.

The presence of copper sulphides in the ore reacting with cyanide requires oxygen similar to gold, according to Elsners equation. If the ore has 7 ppm Au and 460 ppm copper then it is not hard to see the effect on the oxygen demand. Oxygen sparging will assist, however if the oxygen level drops then the leach kinetics will be affected.

For example, a gold concentrator processes typical iron-gold ore, with a processing capacity of 200 tons/day and a gold grade of 10 grams/ton. All ores are calcined in a rotary calciner. The calcined ore is transported into the percolation tank with a mining cart. Lime is directly added to the ore, and the first cyanidation time is 12 hours.
