Autoclave processing of copper mattes

There the purposes are to determine the variables and the indicators of autoclave sulphuric-acid high-temperature leaching of copper mattes and to propose the processing methods of mattes to be processed. The kinetic distinctions of dissolving of copper sulphide (I) and of its alloys with the iron sulphide (II) under the high-temperature autoclave leaching conditions have been determined. The processing method of copper mattes, which provides more finished extraction of copper (by 2-3%), more active performance of process (2-3 times) and the comprehensive extraction of raw material components (in comparison with the known methods), has been proposed. The processing methods of copper mattes, the data for the design analysis are used. The efficiency: the rise of copper extraction, the rate raise of production, the comprehensive use of raw material.
