FIELD: chemical industry; mining industry; other industries; methods of concentration of the sulfide minerals.
SUBSTANCE: the invention presents the method of concentration of the sulfide metals ore and allows to increase effectiveness of the concentration process. The method includes: formation of the suspension containing the water and the ore particles; mixing of the indicated suspension with the foaming agent and the gathering agent with formation of the foam, which contains the concentrated sulfide minerals and collection of the indicated concentrated sulfide minerals. The collecting agent contains N-butoxycarbonyl-О- alkylthionecarbamate selected from the group consisting of N-butoxycarbonyl-О- methylthionecarbamate, N -butoxycarbonyl-О- ethylthionecarbamate, N-butoxycarbonyl-О-propylthionecarbamatel, N-butoxycarbonyl-О-butylthionecarbamate, N-butoxycarbonyl amylthionecarbamate and N-butoxycarbonyl-О-hexylthionecarbamate.
EFFECT: the invention ensures the increased effectiveness of the sulfide minerals separation and concentration production process.
