TECHNOLOGY FOR THE COMPLEX RECYCLING SLAGS OF COPPER PRODUCTION

The article considers the inevitability of copper losses with slag and the possibility of reducing them by various methods and using local secondary technogenic formations. It has been established that the developed and widely used in industry technologies for decopperizing of slag only partially solve the problem and lead to significant irretrievable losses of metal with dump slag. The main factors affecting the magnitude of the casualties are established, and suggestions for reducing their negative impact are recommended. The use of perfect mixing devices is recommended, as in this case, it is possible to achieve a maximum reduction in the residual concentration of copper in the waste slag. Together, it is possible to make an increase in the complexity of the use of raw materials with the organization and implementation of low-waste technology.
