RISE OF COMPLEX PROCESSING OF COPPER AND ZINC RAW MATERIALS AT ALMALYK MINING AND METALLURGICAL WORKS

摘要

The complex technology for processing of copper and zinc concentrates with manufacturing (besides the main products) iron and silicate reminder suitable for construction industry, i.e. for slag casting. This technology is waste-free owing to the fact that clinker of zinc production separated from carbon is processed at melting units of copper facilities. Produced slag after melting for matte are preliminary cleaned for copper and sulphur (by 20-30 percent) via thermo-gravitational method and then are subjected to water-lime granulation. Granulated slag is consequently subjected to low-temperature direct reduction.
