Technological research of process for producing titanium rich slag …
The titanium rich slag was produced from the low-grade ilmenite concentrate, i.e. the low TiO 2 content and the high content of impurities. During the production of the high-grade titanium slag (TiO 2 content: 75–80%), the impurity elements are transferred into the associated alloyed metal (cast iron). Thus, it can be used to smelt the steel.

Slag
Slag is the silicon dioxide and metal oxide mixture left over as a by-product of extracting metal from its ore during the smelting process. Once the metal is smelted out of its ore, the ore appears to be glassy. This glassy appearance is caused by the formation of slag on the ore's surface during the smelting process.

Slag: From By-product to Valuable Construction …
Slag is composed primarily of silica and lime, with concentrations of other minor constituents, including alumina, magnesia, and other compounds. During the fluxing process, slag removes the non-ferrous constituents from the …
Slag: From By-product to Valuable Construction Material
Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed. ...
