Method of mineral raw materials processing |
摘要 |
The invention relates to methods of precious metals recovery from raw materials containing chlorides of earth metals, for example slimes. This method comprises the steps of cinder processing carried out in two steps. At the first step, a secondary enrichment by water washing is carried out with a ratio (S:L) ranging from 1:0.7 to 1:2.5. Then, at the second step, the washed cinder is leached by hydrochloric acid with a ratio (S:L) ranging from 1:2 to 1:3.
