摘要
The method is used for flotation of non-ferrous ores such as copper, copper-pyrite, copper-zinc, copper-molybdenum, lead, lead-zinc, lithium-containing ores, which can be sulphide, oxide, carbonate and mixed ores . It provides easier regulation of the electrolysis process and a higher degree of extraction of the valuable components from the ores. The method involves flotation in the presence of anolyte or catholyte obtained in an electrolyzer equipped with a diaphragm separating the anode from the cathode compartment. According to the invention, the electrolyzer is located outside the flotation chambers and / or air-conditioning tanks, and the cathode and anode compartments are sealed separately. The electrolyzer is operated with electrolyte of circulating water from the flotation process at a current density of 1.0 to 25.0 mA / сm2 and a cathode/anode ratio of 10: 1 to 1:10. The anode and cathode compartments are connected to the flotation chambers and / or conditioning tanks by means of tubular elements, as anolyte or catholyte is supplied to the flotation chamber and / or the conditioning tank for depression of a mineral, and respectively catholyte or anolyte for the activation of a particular mineral, depending on the properties of the incoming material, and the catholyte at initially supplied anolyte, or the anolyte, at the initially supplied catholyte, is fed to another flotation chamber and / or a conditioning tank, in which during the flotation process, is activated a certain mineral or, accordingly, depression of another mineral. Subsequently, purification flotations are carried out if necessary.
