Ilmenite
Thus while ilmenite sand can be directly used in the sulfate or chloride routes for manufacturing titanium dioxide, rutile and leucoxene cannot be attacked with sulfuric acid and only can be used directly in the chloride process. ... Titanium dioxide occurs naturally in the minerals rutile anastase, and ilmenite. The compound has many uses ...Web

Combined production of synthetic rutile in the sulfate TiO
Abstract. This paper describes a novel process for preparation of synthetic rutile using an intermediate, sulfated ilmenite from the sulfate TiO2 process as the feedstock. The synthetic rutile can be obtained by selective thermal decomposition of the sulfated ilmenite, followed by targeted leaching for removal of various impurities.Web

Innovative Process for the Production of Titanium Dioxide
Rutile is often found as beach sands and is the simplest to mine and concentrate in a form suitable for titanium dioxide production. Rutile sand deposits are found in Australia, Sierra Leone, and South Africa. Production of titanium dioxide from rutile now accounts for less than 10 % due to diminishing reserves as compared to 20 % in the 1970s.Web

Titania
Rutile (TiO 2) is isostructural with pyrolusite and manganite, consisting of single chains of edge-sharing TiO 6 octahedra (Fig. 2 K). Rutile is a common residual mineral occurring in the sand and silt fractions of a variety of soils. Anatase consists of edge and corner-sharing octahedra that outline a three-dimensional framework, rather than distinct chains (Fig. 2 M).Web
