Titanium slag is a valuable byproduct of the titanium dioxide production process. It is manufactured through the smelting of ilmenite, during which it is heated in a furnace with carbon-rich materials, resulting in the separation of iron and titanium. The molten slag that forms is then cooled and processed into a coarse granular material known as titanium slag.

One of the primary applications for titanium slag is in the production of titanium dioxide pigment, which is widely used in paints, coatings, plastics, and other industrial applications. Titanium dioxide imparts brightness, opacity, and excellent UV resistance to these products.

Additionally, titanium slag can be further processed to extract titanium metal, which is widely utilized in aerospace, automotive, and chemical industries because of its exceptional strength, corrosion resistance, and lightweight properties.
