The invention discloses a method for enhancing
impurity removal of high-
calcium-
magnesium titanium slag, which comprises the following steps of: S1, spraying gas added with NaCl into molten
titanium slag to perform oxidation transformation treatment in the
smelting and deslagging process of an
ilmenite concentrate electric furnace; s2, the molten
titanium slag obtained in the step 1 flows into an atomizer to be atomized, transformation of the
titanium slag is further promoted, and the
titanium slag is crushed into
powder particles; and S3, the transformed
titanium slag powder is subjected to
impurity removal through a first-stage
hydrochloric acid leaching process, and the titanium-rich material meeting the boiling chlorination requirement can be obtained. The method for strengthening
impurity removal of the high-
calcium-
magnesium titanium slag is in
butt joint with an existing titanium slag production process, heat of the molten titanium slag is fully utilized, rapid transformation of the titanium slag can be achieved, the titanium slag is crushed into
powder particles, one-section leaching is adopted in acid leaching impurity removal of the transformed titanium slag, the process is short,
energy consumption is low, and the method is suitable for industrial production. The method can realize low-cost preparation of the boiling chlorination furnace burden from the high-
calcium-
magnesium titanium slag, and has important significance for guaranteeing the supply safety of
raw material resources in the titanium industry in China and promoting the high-quality development of the titanium industry in China.
