What is the Oxidized Gold Ore. Oxidized gold ores, also known as oxide gold ores, are important gold-bearing resources found extensively around the world. When gold-bearing sulfide deposits are exposed at or near the earth's surface, the oxidation process causes chemical changes that alter the mineralogy of the deposit over time.

Weathered ores contain enough fines that cause severe issues for percolation. For example, oxidized massive sulfide gold ores are so soft and permeable that even crushing below 75 mm does not increase gold recovery (e.g. Filon Sur ore body, Tharsis, Spain and Hassai Mine, Sudan). There can be serious issues in multiple lift and …

Extraction of Elements. Most of the elements do not occur in the free state in nature but these occur in the combined states. In the combined states, metals are usually found in the oxidised form (e.g., Fe 2 O 3, MnO 2, SnO 2 etc.), while non-metals occur in the reduced form such as halide ions (Cl¯, Br¯, I¯)..
