含金物料高温氯化挥发提金试验研究

Experimental Study on Gold Extraction of High-temperature Chlorinated Volatile Gold Extraction

本研究开展了含金物料高温氯化挥发提金试验,通过控制氯化钙添加初始温度、高温氯化终点温度、氯化钙添加量以及氯化挥发时间,可以使渣中金含量降至0.26 g/t,金的挥发率为98.03%。

In this study,gold-containing materials were subjected to high-temperature chlorination and volatile gold extraction experiments.By controlling the initial temperature of calcium chloride addition,the high-temperature chlorination end temperature,the amount of calcium chloride addition,and the chlorination volatilization time,the gold content in the slag can be reduced to 0.26 g/t,and the gold volatility rate is 98.03%.
