Placer Gold Beneficiation Process
Placer gold is generally found in rivers, lakes, valley alluvial layers, etc. The beneficiation process mainly relies on gravity separation, which is widely used in the African market because of its simple operation, low investment, environmental protection and pollution-free.
Gold Carbon In Leach (CIL) Process
Carbon in Leach (CIL) is a gold extraction process based on the linkage of cyanide leaching and activated carbon adsorption, which is widely used in the industrial production of low-grade gold mines (Au content ≥ 0.5 g/t). Its core process includes four modules: cyanide leaching-carbon adsorption-desorption electrolysis-activated carbon regeneration, which can achieve a gold recovery rate of 90%-98%, and the comprehensive cost is 15%-30% lower than that of traditional processes.
Gold Flotation Process
The gold flotation process is suitable for treating gold-containing sulfide ores with fine gold particles and good floatability. During the flotation process, sulfide ores are enriched in sulfide concentrates as carriers of gold. Flotation can also treat polymetallic gold-containing sulfide ores and carbonaceous ores.
Silver Ore Dressing Process
Silver ore beneficiation technology is mainly used to recover silver and associated metal minerals. Silver-containing ores are mainly divided into two categories: silver-gold ores and lead-zinc-copper associated ores.
Gold Carbon In Pulp (CIP) Process
The Gold Carbon in Pulp(CIP)process, a highly efficient and environmentally friendly gold extraction technique, involves the adsorption of gold by activated carbon directly from cyanide slurry. The gold is then extracted through desorption and electrolysis processes. This method is known for its simplicity, low cost, and excellent environmental performance.
