Gold ore Processing technology

The production process of gold ore processing mainly comprises: crushing, grinding, ore dressing three processes:

The crushing process, three stage crushing circuit is the most suitable for modern gold ore crushing manner, can complete the ore crushing and partial dissociation of the follow-up work, so as to improve the grinding efficiency of the grinding process;

in the two section, a closed grinding is grinding process efficient, can make gold mill more fully; beneficiation process, because of various types and properties of gold ore dressing method using different, also have different, but generally using gravity concentration, flotation, mercury, cyanide and now the resin in pulp method, carbon in pulp adsorption method, a new heap leaching technology of gold extraction. For certain types of ores, often using combined gold extraction process.

The first step: crushing and screening - three stage closed circuit crushing

Gold stone by silo large by vibrating feeder evenly sent to jaw crusher or mobile jaw crusher station are crushed; coarse crushed gold ore by screening the vibration sieve, by belt conveyor to the single cylinder hydraulic cone crushers crushing; gold ore in crushed material into the multi cylinder hydraulic cone type of crusher;

Processing Equipment

The second step: Milling

Will pass through the screening vibrating screen 0-12 mm gold powder evenly into the goal by grinding, sieving and spiral classifier, does not meet the requirements of being sent the ball mill to mill;

The third step: dressing

Ore dressing process, because of various types and properties of gold ore dressing method using different, also have different, but generally using gravity concentration, flotation, mercury, cyanide and now the resin in pulp method, carbon in pulp adsorption method, by Jin Xin heap leaching process. For certain types of ores, often using combined gold extraction process.
