Experimental investigation for processing flowsheet of a tin-copper ore

On the characteristic analysis of a tin-copper ore,Flotation-Magnetic separation-Gravity concentration and Gravity concentration-Flotation-magnetic separation-Gravity concentration flowsheets are comparatively investigated for processing the ore.The results of investigation indicates that the Gravity concentration-Flotation-magnetic separation-Gravity concentration flowsheet achieves a superior separation performance to that of Flotation-Magnetic separation-Gravity concentration flowsheet,and it obtained a tin concentrate assaying 66.36% Sn with 63.96%recovery and comprehensively recovered a copper concentrate assaying 23.26% Cu with 37.39% recovery,from the ore assaying 0.913% Sn and 0.423% Cu;moreover,it produced an iron concentrate assaying 63.93% Fe with recovery 7.97%.
