17 - Flotation of Gold Ores

2017-2-16 · 17.5 FLOTATION OF GOLD-CONTAINING MERCURY/ANTIMONY ORES In general, these ores belong to a group of difficult-to-treat ores, where cyanidation usually produces poor extraction. Mercury is partially soluble in cyanide, which increases consumption and reduces extraction. A successful flotation method [5] has
