Cyanide leaching process is one of the common gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree. The factors that affect gold leaching include grinding fineness, pH, temperature, cyanide dosage, pulp-solid-liquid ratio, leaching time, impurities in ore and amount of leaching aid and so on. This article will discuss how grinding fineness influence gold leaching process and its related problems and improvement methods.

The environmental-friendly gold leaching reagent has a series of advantages including low toxicity, simple use, and high gold leaching rate when replacing sodium cyanide under conventional alkaline conditions. A certain mining company uses sodium cyanide as gold reagent in its heap leaching plant. In order to verify the feasibility of using environmental-friendly gold leaching reagent to replace sodium cyanide in heap leaching process, the company conducted a heap leaching industrial production test.

High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly used gold processing methods for high-sulfide gold ores.

Quartz is generally associated with hydrothermal alteration at low and medium temperatures, under which gold is easily enriched to reach industrial grade. That’s why quartz vein gold deposits are formed. Quartz vein gold ore is common in nature and its extraction has great significance to economic development.

Flotation agents are chemical agents used in the mineral flotation process which can adjust the surface properties of the minerals, increase or decrease the floatability of the minerals, and make the pulp properties and foam stability more conducive to mineral separation. Common flotation agents are collectors, foaming agents, inhibitors, activators, dispersants, flocculants and defoamers. This article mainly introduces flotation defoamer.
