How Are Metal Slags Made

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.
