The premise of beneficiation is to completely separate target minerals from gangue minerals,so the proportion of intergrowth minerals has an important influence on the beneficiation indexes.Without increasing investment,it can reach the goals of fully disintegrating,lowing the level of intergrowth and improving the floatability of target minerals by reforming process and regrinding middling(roughing and scavenging concentrates)during the full process.Field practice showed that after process Reformation,the concentrate grade had increased from 37×10-6 to 45×10-6,the god recovery rate was risen by 0.6%,and economic benefits amounted to 11 974 thousand Yuan per year.
