Abstract

An energy-saving scheme has been developed for a nonwaste processing system for refractory Sn-concentrates together with Zn-containing slags. The search for a new system was carried out in the following areas: the choice of a method for continuous, high-temperature and intensive processing of concentrates and the selection of high-performance melting equipment that implements this method; the formation of resource-saving technology; development of an energy-saving thermal scheme in the framework of which the selected melting equipment and non-waste technology will operate. In case of implementation of the proposed system, thermal efficiency will increase 1.42 times, and the total waste-free indicator will be 5.3 times higher than in existing fuming plants.
