双氧化法预处理含金锑渣的研究

Study on pretreatment of gold bearing antimony slag by method of double oxidation

对湖南某地含金锑渣进行了提金实验，采用双氧化法预处理该锑渣能有效消除炭、锑对氰化提金的影响，详细考查了双氧化法预处理过程中影响氰化提金的几个主要作业因素，在所确定的最佳条件下，金的浸出率可达８６７４％。

The experiment of extracting gold from gold bearing antimony slag of a place in Hunan by method of double oxidation was made.Using this method to pretreat antimony slag,the influence of carbon and antimony on cyanide process for gold extraction can be removed effectively.This paper made a detailed investigation on main factors influencing cyanide process for gold extraction when using method of double oxidation to pretreat the slays.Under the optimal conditions,the gold leaching rate can reach 86.74%.
