摘要：
An urgent task at the present time is the disposal and processing of large-tonnage waste of titanium production of Ust-Kamenogorsk titanium-magnesium plant of the Republic of Kazakhstan. This work shows research on the development of sludge technology with the extraction of titanium dioxide and calcium nitrate, which will eliminate the formation and discharge of technological waste into the environment. Ammonium fluoride processing of cakes from sludge leaching made it possible to first isolate silicon fluorides in the form of fumes, and then sublimate titanium fluorides. Silicon and titanium fluorides were converted to silicon and titanium dioxides by alkaline hydrolysis.
