Abstract: This article considers a technical solution to the production of abrasive powders according to the standard ISO 11126 from copper slag and nickel slag with the use of air classification. Justification of the selection of air classifier for the process of classification of copper slag is performed. The results of laboratory studies on the effect of the consumption concentration on the quality of the separation of slag particles in apparatus with an inclined louver lattice with reverse air suction are presented. This article then discusses the dependence of the material separation boundary on the air flow rate through the classifier’s louver. Based on the theoretical calculation, an industrial apparatus with a capacity of 50 t/h on initial raw materials was developed, laboratory tests were industrialized, and the results of industrial tests were shown. Industrial testing was carried out and the results of are shown.
