The sludge from the smelting plant and the converters formed as a result of the smelting process are processed in a flotation plant in order to extract the remaining copper.
The technological process is controlled and managed with an automatic system. The flotation method of enrichment is used, where two products are obtained:
» copper concentrate, which is returned back to the smelting production process;
» Iron-Silicate fines, part of which is stored in a depot in a tailing dam built according to the latest European standards.
