氰化法是从矿物中提金最主要的方法。但它存在的致命缺点是氰化物有剧毒 ,此外 ,对含铜高的矿物不适用 ,浸金效果差 ,金浸出率仅为 50 .0 %～ 70 .0 % ,且试剂消耗高。针对多种类型的矿物 ,采用非氰化浸出 ,并采用北京化工冶金研究院研制的Ｒ4 1 0特效树脂选择性吸附回收金 ,从
Cyanide is the most important method of extracting gold from minerals. However, it has the fatal flaw that the cyanide is highly toxic. In addition, it is not suitable for high copper-bearing minerals and the effect of leaching gold is poor. The gold leaching rate is only 50.0% -70.0%, and the consumption of reagents is high. For many types of minerals, the use of non-cyanidation leaching, and the Beijing Institute of Chemical Metallurgical Research R4 1 0 special effects resin selective adsorption recovery gold, from
