<p>The present disclosure relates to a process for recovering a valuable metal from a sulfidic material. The process comprises subjecting the sulfidic material to a hydrometallugical step followed by selective removal of elemental sulful from the metallurgical residue before a final metal recovery step, such as cyanide leaching. The process improves the over-all process economy and reduces the cyanide consumption as a result of the selective removal of elemental sulfur.</p> |
