método de recuperação de cobre a partir de um concentrado de sulfeto de cobre |
摘要 |
<p>A method of recovering copper from a copper sulfide concentrate comprising a copper arsenic sulfosalt or a copper antimony sulfosalt, using pyrite as a catalyst. The concentrate and pyrite are added to an acidic sulfate leach solution. The copper is leached from the concentrate, in the presence of an oxygen-containing gas, under conditions whereby the pyrite is substantially unoxidized. The pyrite:copper sulfide ratio of the pyrite being added to the copper sulfide present in the concentrate being added is at least 1:3. The pyrite may be maintained at a concentration in the leach solution of at least 9 grams per liter. The leached copper is recovered from the solution by conventional methods.</p> |
