It is very hard to reach the grade above TGC 96% just by the stage grinding and flotation processing. To get higher grade above TGC96% or even above TGC 99.95%, deep processing should be applied. General processing technologies for graphite ore are summarized as below: Physical processing technology: Crushing & grinding solution

refractory gold minerals; locking of submicroscopic gold in sulfide and sulfarsenide mineral structures. Gold process mineralogy address all issues related to gold ore processing by the detailed study of an ore or a mill product. The methodology is widely used as a predictive tool in feasibility studies and during the process

Ore processing consists of the following stages: crushing and grinding of the ore addition of process water (generally decanted from the tailings pond) to form a slurry addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution

In the minerals industry, dry grinding plants are primar-ily used when the downstream preparation process requires dry material, or in order to save valuable water resources. Plants from ThyssenKrupp Industrial Solutions are in successful operation all around the world, grinding and drying gold ore, iron ore, iron ore concentrate, lime-
