MINERAL COMPOSITION OF PROCESSING WASTES OF TITANOMAGNETITE ORES FROM THE KUSA DEPOSIT (SOUTH URALS)
Abstract
The dumps of processing wastes (tales) of titanomagnetite ores from the Kusa deposit located in the southwestern margin of the settlement of Magnitka, Chelyabinst district (South Urals) began to form in 1948. The modern area of the dumps is ~ 3 km2 ; no data are known on mineral composition of the dumps. A new sample 1706.2 g in weight contains (vol. %) amphibole ~ 46, chlorite ~ 30, garnet ~7.2, magnetite ~ 4.3, ilmenite (with hematite) ~ 1.8 and other minerals. Fractions of –0.316 + 0.125 and +63 mm comprise 64.6 and 3.5 % of the volume, respectively. New microprobe analyzes of ilmenite, hematite, pargasite, ferropargasite, enstatite, pigeonite, epidote, staurolite, clinochlore, almandine, pyrite, bravoite, pyrrhotite and chalcopyrite are given. The results of studies of other researchers are briefly summarized. Small fractions of technogenic dumps in the settlement of Magnitka may be of practical interest for extraction of remained magnetite and ilmenite or production of silicate (garnet and amphibole) silicates for abrasives or ceramic fillers. The larger fractions could be a suitable material for pedestrian pathways in squares and parks.
