Titanium dioxide, which is used as a white pigment in products such as toothpaste, is derived from which mineral?

Explanation

Ilmenite, FeTiO₃, is an economically important titanium mineral used as feedstock for titanium-dioxide pigment production. Rutile is another important source, but it is not listed here. Titanium dioxide is valued as a white pigment for its light-scattering properties.
