Способ переработки титаномагнетитовой руды Колвицкого месторождения

Abstract

The research results of hydrometallurgical processing of titanomagnetite ore of the Kolvitsky deposit of Kola region have been presented. The method is based on selective extraction of titanium from ore by solution, which contains ammonium and fluorine ions. The most promising results were obtained utilizing solution with fluorine ions concentration of 0,95 mol/L and ammonium ions concentration of 0,5 mol/L. Under these conditions the Fe/Ti ratio in ferreous concentrate was increased 3 times in comparison with original ore. Concentration of fluorine ions in ammonium fluoride solution affects selectivity of titanomagnetite ores processing and shows principal possibility to control process using this parameter.
