摘要
针对微细浸染型难选金矿载金粒度细、泥化严重、矿石品位较高、直接氰化回收率不到50%的现状,采用正交析因法进行碱浸预处理及氰化优化条件研究,确定了最优处理条件,氰化回收率达到80.23%。
According to the properties of micro-disseminated refractory gold ore,such as fine gold-bearing size,high content of sliming, high grade of gold and low recovery rate （ 〈 50% ）if using direct eyaniding,the optimum conditions of alkali leaching pretreatment and the cyaniding were studied by orthogonal test. The best treatment condition was determined under which the recovery rate of gold in cyanide process achieved 80. 23%.
