Abstract

As part of the work, a low-waste resource-saving technology for processing diopside with the extraction of scandium compounds and the associated production of a wide range of large-tonnage mineral products has been developed. The technology of solid-phase extraction of scandium compounds using solid impregnates based on macroporous activated carbons modified with phosphonic acids has been proposed. The main directions of neutralization and processing of mother liquors and solid products formed in the process of extracting scandium compounds are proposed. Samples of magnesium fertilizers, red pigments for building mixtures, as well as precursors of titanium compounds were obtained as commercial products.

Keywords: Scandium, diopside, extraction, magnesium, titanium
