摘要 |
FIELD: waste disposal methods. ^ SUBSTANCE: invention relates to waste processing technology, wherein waste contains titanium and silicon compounds, and can be used to improve environmental situation and also to extend source of raw materials to produce commercial products such as titanium dioxide and silicon carbide. Production thereof from abrasive processing waste involves acid treatment of titanium-containing raw material and isolation of desired products. Raw material utilized is titanium-based abrasive processing waste. Waste is preliminarily subjected to drying, removal of textile tails, and subsequent separation of titanium constituent from silicon carbide on electromagnetic rolling analyzer operated at magnetic field intensity 10000-12000 Oersted. Titanium constituent is treated with sulfuric acid to produce titanium dioxide. ^ EFFECT: improved environmental condition and developed production of commercial titanium dioxide and silicon carbide. ^ 2 tbl |
