Precious metal extraction method |
| abstract |
FIELD: metallurgy. n SUBSTANCE: invention refers to extraction methods of precious metals and can be used for extraction of precious metals from mineral raw material containing chlorides of alkali and alkali-earth metals, e.g. sludges of potassium production. Extraction method of precious metals from clay-salt waste - sludges of potassium productions - containing chlorides of alkali and alkali-earth metals involves bulk concentrate obtained from them, roasting, leaching of precious metals from stub end and sorption of precious metals. Bulk concentrate is obtained till content of chlorides is 15 to 30%. Before roasting, the concentrate is granulated and subject to roasting at temperature of 500-950°C. Precious metals are leached from stub end by means of salt acid solution. n EFFECT: increasing complex extraction of precious metals. n 5 tbl, 4 ex |
