A study on the beneficiation ability of manganese-containing technogenic raw materials

Abstract

The work presents the results of studies on obtaining ferromanganese concentrate from technogenic manganesecontaining raw materials with grain size less than 10 mm. It is found that the main valuable minerals of the feedstock are psilomelane, pyrolusite, bementite; among the rock-forming minerals, quartz and kaolinite, often saturated with finely dispersed iron compounds, prevail. Sieving and concentration of raw materials of - 10 + 5 mm and - 2 + 0,2 mm in two-chamber jigging machine with separation of two concentrates and tailingпs allowed to obtain a joint manganese concentrate with 35,1 % manganese content, 11,5 % iron content with 78,23 % manganese recovery. The obtained manganese concentrate is suitable for further metallurgical processing.
