Abstract: Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry.

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

Mined ore which has a copper grade of less than 1% is turned into copper concentrate with a purity of about 30% at mine site and transported to the Toyo Smelter & Refinery. In addition to copper, copper concentrates contain about 30% each of iron and sulfur, and trace amounts of gold, silver and other precious metals, all of which are recovered.
