Abstract
Description
technical field
[0001] The invention relates to a method for producing artificial rutile, in particular to a method for producing artificial rutile by using high-titanium slag. Background technique
[0002] At present, in the domestic and foreign titanium dioxide raw material markets, the raw materials for "high-grade chloride titanium dioxide", such as natural rutile and artificial rutile, are particularly in short supply. High titanium slag has become the main raw material for the production of titanium dioxide by the chloride method. The high-titanium slag prepared by the current submerged arc furnace reduction method contains about 60-75% TiO 2 , low grade, not suitable for "high-grade chloride titanium dioxide" raw material. Therefore, it is imperative to improve the grade of titanium slag to meet market demand. In high titanium slag, black titanite is the main phase containing titanium, and its TiO 2 The content is relatively high (60%-80%), which is an early crysta...
