This paper describes the reasons of withdrawal of electrofilter dusts from Vanyukov furnace charge. There is proposed a flow-sheet of separate processing of this dust. There are given the qualitative and quantitative results and indices of pilot testings, concerning to the withdrawal of dusts from Vanyukov furnace charge. There are shown the results of investigations of separate processing of Vanyukov furnace dusts in ore-thermal furnace with extraction of cooper and precious metals to matte, and extraction of zinc, lead, arsenic and antimony to slag and secondary sublimates. There is carried out the analysis of impurities distribution among the dust processing products and their influence on the quality of blister and cathode copper.
