Gold Ore - an overview | ScienceDirect Topics
Gold containing ores may be broadly classified as non-refractory (free milling) and refractory. Non-refractory ores are relatively easy to process, and the available gold may be recovered by fine grinding, gravity concentration, and direct cyanidation. Refractory ores, however, require pretreatment before cyanidation to liberate encapsulated gold particles. Primary gold ores
