Abstract

Comprehensive processing is the most important principle of all mineral and raw materials industries, while waste should be considered as technogenic deposits. The coal processing waste of the Berezovskaya CCF contains up to 4500 g/t of titanium, up to 10 g/t of scandium, and up to 150 g/t of rare-earth elements. As part of the agreement with the Ministry of Science and Higher Education of the Russian Federation 075-15-2022-1194 dated September 30, 2022, a pilot plant was created for the production of pilot batches of rare and rare-earth element oxides and for the production of pilot batches of scandium and titanium (IV) oxides, and experimental tests were conducted on it. The article focuses on the extraction of titanium dioxide using the created plant. It has been found that the adopted method can achieve a concentration of titanium that is 9 times higher than the initial content in the raw material.

Keywords

Coal waste, pilot plant, rare and rare-earth elements, titanium dioxide, leaching.
