目前,国内黄金矿山的氰化流程多系处理浮选精矿,且多采用简单的一次浸出,一次洗涤流程。由于浮选精矿的矿物组成复杂,在浸出过程中除贵金属外,许多伴生矿物都程度不同的与氰化物反应,这些化学反应不但消耗了大量氰化物,且消耗了使贵金属转入溶液时必不可少的溶氧量,多数氰化指标恶化的原因都 At present, the cyanidation process of gold mines in China mostly processes flotation concentrates, and more often uses a simple leaching process and a washing process. Due to the complex mineral composition of flotation concentrates, in addition to the precious metals in the leaching process, many associated minerals react with cyanide to varying degrees, which not only consume large amounts of cyanide but also consume valuable metals Essential dissolved oxygen, most of the reasons for the deterioration of cyanide indicators are
