| 发明名称 | Method for leaching zinc from a zinc ore | ||
| 摘要 | A method for leaching zinc from a zinc-bearing carbonate ore, the method comprising the steps of: subjecting the zinc-bearing carbonate ore to elevated temperatures of between about 300° C. and about 900° C. thereby producing a roasted ore; subjecting the roasted ore to an aqueous acid or alkali leach thereby producing an aqueous zinc solution; and subjecting the aqueous zinc solution to a zinc recovery step. | ||

| 主权项 | 1. A method for leaching zinc from a zinc-bearing carbonate mineral, the method comprising the steps of: subjecting a material consisting essentially of a zinc-bearing ore containing the zinc-bearing carbonate mineral to elevated temperatures of between about 300° C. and about 900° C. in the absence of additional reactive reagents, thereby producing a decomposed material and carbon dioxide; subjecting the decomposed material to an aqueous acid or alkali leach thereby producing an aqueous zinc solution; and subjecting the aqueous zinc solution to a zinc recovery step. | ||
