The technological process of extracting gold from ore raw materials includes preparatory (crushing, grinding), dressing (gravity, flotation) and metallurgical (cyanidation, melting, roasting) operations.
The chosen technological scheme should ensure high gold recovery, integrated use of raw materials, low production costs, and minimal environmental pollution with production waste.
Initial raw materials for obtaining an alloy of gold ligature are CS, the content of impurities in the finished products of the enterprise depends on their quality.
