The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;

The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall …

The operator can sell the free gold and send the sulfides to the refiner if they contain additional values. The spiral classifier separates the shaker table tailings into fine and coarse fractions. The coarse material is directed back to the grinding circuit to liberate more value, and the fine material is directed to the waste settling pond.

Ultra-fine disseminated gold particles can be trapped within the mineral matrix, even at fine grind sizes. The ore can contain highly reactive minerals that consume free cyanide or oxygen. In addition, the ore can contain preg-robbing elements such as organic carbon that will re-adsorb the dissolved gold as it is leached.

Gold particles are very difficult to be concentrated when the material is a slurry of fine-grinding minerals. The same happens when the ore is rich in clayminerals. This forms a muddy-viscous pulp that must be adequately dispersed with caustic soda or dispersants to create conditions for gold to be concentrated by gravity processes.

ore. Relatively coarse gold particles that are liberated from the gangue mineral phase by crushing and grinding are readily recovered by gravity techniques, because of the large difference in specific gravity between gold (SG 19.3) and most gangue minerals (SG 2 to 3). For gold ores that are amenable to gravity separation, recovery of the coarse,
