The article is devoted to the development of an effective technology for beneficiation of sulfide ores. The article refers to the issue of increasing the recovery rate of flotation concentrate when working with copper-nickel ores. The effectiveness of ore pre-treatment using magnetic pulse action has been proven based on the technological effect and mineral analysis of concentrate. The article addresses the peculiarities of adaptation of industrial magnetic pulse equipment (MPP) to the features of the technological process of beneficiation of sulfide copper-nickel ores. When adapting the equipment, technological effects obtained during laboratory testing, certain ranges of rational technological modes of the MPP, geometric characteristics of units of the beneficiation apparatus and the speed of ore flows were taken into account.
The article is published as a platform for discussion.
