【摘要】 某精炼厂金氰渣中金含量为24.80 g/t,损失严重。为查找金的损失原因,提高经济效益,对该氰渣进行了详细深入的工艺矿物学研究。结果表明,样品中的金绝大部分以单体形式损失,样品整体粒度很细导致氰化时样品分散效果不好,是影响金浸出的最主要原因。更多还原

【Abstract】 A gold grade of a cyanide residue of refining plant is 24. 80 g/t. The loss of gold is serious. In order to find the reasons of the loss of gold and to improve the economic benefit,the process mineralogy of the cyanide residue was studied in detail. The results show that most of the gold in the sample is lost in the form of monomer. The whole grain size of the sample is very fine,and the dispersion effect is not good. It is the most important influencing factors for the gold leaching.更多还原
