Structural and textural features, phase and chemical compositions of high-copper matte and solid residue from atmospheric copper cleaning operation, which is the main operation in the technological scheme of sulfuric acid leaching of matte, were studied. Studies of the structural and mineralogical composition of the products were carried out using modern methods of electron microscopy (SEM and PCMA) and X-ray diffraction analysis.

In the course of work new data on the mechanism of copper precipitation and leaching of iron triad elements were obtained. It is shown that in the conditions of leaching of high-copper matte for copper purification operation the cementation mechanism of copper precipitation is dominant.

On the basis of theoretical ideas about chemical interactions the indicators of quantitative distribution of metals and sulfur in the copper purification operation are calculated, which correspond well with the results of experiments.
