Experimental Study on Purification of Magnesite Ore in Liaoning Province

Abstract:

A region of liaoning low-grade magnesite ore products mainly for magnesite ,the gangue minerals are mainly hematite,calcite,chlorite,quartz,etc.This experimental using a roughing secondary selected single reverse flotation process,with hydrochloric acid, sodium silicate,sodium hexametaphosphate for adjustment,LKD for collecting agent,the ore are studied,in the conditions of mine ore SiO₂ content is 0.85%,MgO content is 95.53%,Fe₂O₃ content is 0.82%,obtain concentrate SiO₂ content is 0.17%,Fe₂O₃ content is 0.69%,concentrate grade (MgO content) is 97.31%,the recovery is 78.86% of the experimental index.The experimental of related mineral flotation purification provide identification and reference.
