Förfarande för lakning av metallsulfidmineraler |
| 摘要 |
<p>The invention relates to a method for the sulphate-based leaching of metal sulphide minerals, such as chalcopyrite, CuFeS<SUB>2</SUB>, containing ore in atmospheric conditions. It is beneficial for the leaching of metal sulphides that the sulphide to be leached is treated before leaching or at the beginning of leaching with a sulphide salt that is more noble than the sulphide or the components it includes.</p> |
