Research on the acid decomposition kinetics of non-conventional titanium raw materials of the Arctic Zone of the Russian Federation

Acid leaching kinetics of loparite, perovskite, and titanite concentrates by hydrochloric and nitric acids has been studied. Kinetic parameters of acid leaching have been calculated and fitted to several kinetic models. Deeply kinetic study gives us the knowledge of acid leaching of titanium-containing minerals, and parameters obtained allow us to choose the optimal conditions of the mineral processing.
