混汞法

根据含金原料中金的性质不同，从含金原料中提取金的方法主要有重选法、浮选法、氰化法、难处理矿石处理法、非氰化浸出法和混汞法等方法。

On the basis of different properties of gold in the materials which contain gold , the methods that gold can be extracted from them mainly include gravitation separation , flotation separation , cyanidation , the treating method of refractory gold ores , non-cyanide process and amalgamation and so on .

混汞法采金地区的汞污染研究进展

Study on progress of mercury contamination to the environment associated with gold extraction by amalgamation

由于混汞提金法的广泛与长期使用，汞污染在不同的金矿及周围地区都有程度不一的表现。

Because of the wide and long-term use of extraction in this way , different gold mines and the areas around them all show different degree of mercury pollution .

但采用混汞&炭浸法工艺，金的浸出率可提高1.61%。

The leaching rate of gold can increase 1 . 61 percent when the technology of amalgamation-carbon leaching was applied .
