    Abstract:

    The copper concentrate which contain sulphides (in principal chalcopyrite and pyrite) are oxidized in water, in presence of air at pressure about 4-7 atm and temperature of 125 - 135°C.The paper presents the decisive influence of hematite content to the efficiency of sulphides oxidizing. The proposed process is clean, efficient and can be applied also to concentrates with low copper content.

    Keywords:

    concentrate oxidizing, autoclaving with air, hematite content
