An under-standing of, and ability to control the pulp chemistry during oxidation has resulted in the successful Activox® treatment (

A Review of the Cyanidation Treatment of Copper-Gold Ores and

2020/5/21 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. For this reason, the industry has been adjusting its methods
