溴化法浸出提取金和银

Gold-silver Concentrate Leaching by Bromide Process

讨论了溴化法提取金银的热力学条件，用高银金精矿进行了溴化法浸出实验，结果表明，一次浸出焙烧矿，金的浸出率９８％，银的浸出率９４％，效果明显。

The thermodynamics of bromide process in gold and silver leaching was considered in this paper. Laboratory tests to the high silver-gold concentrate have been carried out by bromide process. Results showed that by this method with leaching roast ore only once, the recovery efficiency of gold was 98%, and the recovery efficiency of silver was 96%.
