TREATMENT METHOD OF RAW MATERIALS CONTAINING TITANIUM

摘要

Production of titanium dioxide which is characterized by recovery of reusable H2SO4, high pure Fe oxide and hydroxide and fractional recovery of Mn, V and Cr, etc. from FeSO4?nH2O and waste acid of 20 - 40% H2SO4 containing abundant heavy metallic ions which are by-produced in the production of TiO2 by dissolution of Ti raw materials such as ilmenite, steel production slag, such as electric furnace slag, convertor slag with H2SO4.
