PROCESS FOR OXIDATIVE LEACHING OF COPPER FROM SULFIDIC MATERIALS

A process for the oxidative copper leaching from sulphidic materials by using oxidants. Said sulphidic materials are continuously, together with an oxidant, mixed at from 20 to 95 degrees Celsius. The above-mentioned solution can be utilised at the hydro-metallurgic production of metals during which...

Summary:A process for the oxidative copper leaching from sulphidic materials by using oxidants. Said sulphidic materials are continuously, together with an oxidant, mixed at from 20 to 95 degrees Celsius. The above-mentioned solution can be utilised at the hydro-metallurgic production of metals during which a layer of a solid reaction product is formed on a leached surface during said leaching process.
