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.
The results of research of oxidative smelting technology of ore concentrate from Pechenganickel Combine with increased content of magnesium oxide are presented. The experiment was carried out in laboratory conditions and at the enlarged plant with top oxygen blowing for matte of different composition. The process of depletion of the obtained slags was investigated. The results of slag research by X-ray microanalysis are presented.
