Abstract: About 65% of global production of titanium concentrates is based on the processing of alluvial ores and only 35% on the processing of ores from primary deposits. As a rule, the process of alluvial enrichment is carried out in two stages. The first stage consists of primary gravity concentration, which produces a rough collective concentrate. The second stage consists in selection (finishing) of the said collective concentrate by methods of magnetic and electric separation to obtain separate rutile, ilmenite, zircon, monazite, distensillimanite, staurolite and other concentrates. In this article technological substantiation of combined technology of processing of titanium-zirconium sands of Tuganskoye deposit is given. Studies of material composition and enrichment of placers have been carried out. The purpose of researches was to obtain quartz sands of "glass" quality with the use of electric separation. The requirements for glass sands are quite high. The main requirement is the minimum content of impurities. The object of research was ore sands of Tuganskoye deposit from which ilmenite, rutile-leucoxene and zircon concentrates are obtained. In 2006 at CJSC "Tugansk Mining and Processing Plant "Ilmenit" was organized pilot production for integrated processing of ilmenite-zircon sands of the South-Alexandrovsky area of the Tuganskoye deposit. Its development was completed in 2016 with the decision to design and subsequently build a larger capacity industrial plant. The high efficiency of the associated extraction of quartz sand from titanium ores has become a key aspect of ensuring the profitability of the project for ore sands mining and beneficiation at the Tuganskoye deposit This paper shows the possibility of using corona-electric separation to obtain commercial quartz concentrates. The necessity of further research and modeling of electrostatic separation in high-tech apparatuses of domestic production was determined.
