METHOD OF PROCESSING LEUKOXENE CONCENTRATE Russian patent published in 2017 - IPC C22B34/12 C22B1/02 C22B3/04

Abstract RU 2623564 C1

FIELD: chemistry.

SUBSTANCE: processing method of leucoxene concentrates includes melting concentrate together with soda. While contained in concentrate silicon dioxide interacts with soda with the formation of water-soluble silicates. Melting product is subjected to grinding and leaching with water. The result is a sludge based on titanium dioxide, suitable for further processing on traditional technologies with the receipt of pigment titanium dioxide, titanium metal and other titanium products.

EFFECT: reducing environmental risks by eliminating the use of acids and alkalis.
