FIELD: parting technology. SUBSTANCE: in order to obtain high- purity titanium dioxide, raw material is stripped with fluorination agent and simultaneously leached with aqueous solution of ammonium fluoride compound at solids-to-liquid ratio equal to (0.5-2):1. Posttreatment is further carried out at pH 6.5-7.5. EFFECT: specified process and increased degree of separation. 4 cl
