Method of smelting titanium slag through two-step method

The invention relates to a method of smelting titanium slag through a two-step method, and belongs to the field of metallurgy. The method of smelting the titanium slag through the two-step method comprises the following steps that titanium concentrate serves as a smelting raw material, electric furnace smelting operation is conducted, and the titanium slag is obtained, specifically, the grade of TiO2 of the titanium slag is 72%+/-1%; and then slag tapping operation is conducted, a reducing agent is blown to a slag pot in the slag tapping process, the titanium slag which is discharged from a furnace is reduced to form a titanium slag product, specifically, the grade of TiO2 of the titanium slag product is 74%+/-1%. Compared with an existing titanium slag smelting technology, the method hasthe advantages that the technological operation is easy, by means of the control over the reduction degree of the titanium slag, the content of FeO in the slag is improved, the content of the low-valence titanium oxide is red
