Method, unit and precious metal extraction unit for improving the yield in precious metal extraction by sorption-leaching processes |
| abstract |
The invention relates to a process, a unit and a gold and/or silver extraction unit for improving the yield in a sorption-leaching process (10) for extracting precious metals, in which the efficiency of the process is limited in particular by the organic carbon and/or sulphide sulphur content in the raw material, such that quantitative residual amounts of precious metals remain in the sorption sludges produced during the sorption-leaching process (10); involving the steps of: processing of the sorption sludges in preparation for an oxidising roasting step (80), wherein the sorption sludges are dewatered (18), dried (24) and granulated (26); oxidising roasting (80) of said processed sorption sludges; and feeding of the roasted sorption sludges to a further leaching or sorption-leaching process (10). |
