Abstract. The subject of research is the efficient use of electric separation process at the final stage of processing crushed basalt to extract native copper concentrate. This process operation is included into the integrated waste-free processing technology of basalts. Since basalt has a high content of titan magnetite, the pre-ground mixture is separated onto a magnetic separator, and then magnet-resistant part, including native copper, is passed through the electrostatic separator.

During the studies, the rational size fractions for electrostatic separation were defined, the output amount of copper concentrate for the three size fractions of basalt and also the dependence of the concentrate amount on the electric field intensity of the separator were set.

Since in real conditions the mixture of size fractions entering onto the separator lies between the recommended ranges, the correlation analysis of copper concentrate output dependence on the ratio of the size fractions and the electric field intensity was carried out. The obtained dependence allows predicting the efficiency of extraction of copper concentrate from the basalt, and at the final stage of its processing it is recommended to use the process of electrostatic separation.
