Some gold ores are refractory ores. They are difficult to process with regular cyanide leaching. This is because sulfide minerals encapsulate the gold particles. To address this, a pre-oxidation step is required. It breaks down sulfide minerals and exposes gold particles to the leaching stage. There are a few pre-oxidation methods:

Ore is a deposit in Earth's crust of one or more valuable minerals.The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction. . It is a …
Gold mineral processing plant. Gold ore processing plants are common including washing & screening, crushing & grinding, beneficiation, concentration, drying or smelting. 1. Washing & screening: It is mainly to remove the mud in the placer gold ore, or to make the particle size meet the requirements of the sorting operation. 2.
Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts …
