Some improvements for the selective-collectively-selective technology which complex realization allows to increase technological efficiency of charge processing of high-grade and coppery ores is offered. The following was the basic priorities at development of circuit designs and operating parameters: increase of pyrrhotine yield in an independent product, improvement in quality of copper and nickel concentrates and also reduction of emissions of sulfur dioxide in atmosphere at a stage of pyrometallurgical processing of end concentrates at the expense of decrease in them quantities of iron sulphides.
