A systematic review of sustainable gold extraction from raw ores

In the context of its processing, gold deposits are typically classified, for the purposes of simplification, as: 1) free milling, and 2) refractory ores (including complex and carbonaceous). Based on their mineralogical characteristics and their mineral processing techniques required to liberate them, however, gold ores can be classified 01 Non-cyanide extraction method of oxidized gold ore. Traditional non-cyanidation methods include gravity separation, flotation separation and magnetic separation. These methods use the difference in physical properties between gold minerals and other non-gold minerals in the ore to achieve the separation and enrichment of 4 Kinds of Oxidized Gold Ore Extraction Processes Xinhai
