Perspective raw material for the production of titanium and tinan-containing products

Abstract

The mechanical activation of a hydrated product (GP), isolated during the treatment of perovskite with nitric acid, leads to the dispersion of particles, amorphization of their surface and the formation of microdefects, which significantly increases its chemical activity during interaction with sulfuric acid. Of interest is the addition of a fluoride compound (NH4HF2) to the concentrate prior to decomposition, initiating acid leaching of the components into the liquid phase. The obtained results can be used for realization of nitrogen-sulfuric acid variant of perovskite technology with obtaining titanium-containing and rare-metal products.
