Compared with processing high-TiO2 concentrates such as ilmenite ores, processing an anatase ore to achieve impurity levels acceptable for pigment production is more difficult because of the extensive number of accessory minerals presentRutile, with its low impurity levels, is ideal for processing by the chloride process, but resources of rutile are limited compared with ilmenite.
Currently there are a number of large anatase deposits in the world that have been characterized and potential processing conditions investigated, but at present none have been developed commercially to generate suitable feedstocks for the production of titania pigment.
