Abstract
The problems of using the oil-bearing leucoxene ores of the Yarega deposit as raw materials for the production of titanium and pigment TiO2 are discussed. The results of the investigation of two variants of the technological process predicting the preparation of artificial rutile (for processing by the chloric method) and anosovite (for sulfuric acid decomposition) with the accompanying preparation of synthetic wollastonite are presented. The developed process includes reducing roasting of a leucoxene concentrate under various conditions, magnetic separation for the removal of free quartz, and chemical desiliconization of the magnesium fraction (siliceous titanium concentrate) to form the end products.
