难处理混合型金矿的浸金研究

Study of Leaching Out Gold from Refractory Mixed Type Gold Ores

探讨了用非氰化法从混合型金矿中浸取金的可能性。主要研究了硫脲法浸金时，硫酸铁浓度、硫脲浓度、酸度、温度、浸取时间及固液比等实验条件对金浸出率的影响，并与微波等方法进行了比较。

The feasibility to leach out gold from mixed type of gold ores by non-cyanide process and the effects of the concentration of ferric sulfate and concentration of thionrea solution, acidicy, temperature, le aching time and solid-to-liquid ratio on gold leaching rate were studied through the leaching of gold by thiourea in this paper The method of leaching of gold was compared with microwave technique and other leaching methods.
