Ilmenite - Wikipedia

Mineral sands contain titanium dioxide (TiO 2), a compound primarily used to produce white pigments, a raw material very widely used in paint, plastics and paper.Like titanium dioxide, zircon is used in the ceramics industry and in numerous applications such as abrasive or abrasion-resistant materials, jewelry (zirconium dioxide), the nuclear industry (zirconium metal), dentures, etc.

Sibelco - Mineral sands | Ilmenite, Rutile & Zircon

The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.
