尾矿中回收铁和锡的工艺试验研究
The Process Experimental Study on Iron and Tin Recovery from Tailings
摘要
Abstract
The high gradient magnetic separation (HGMS) experiments were carried out for the railings (TFe =39.46％,Sn =0.71％) from plant of 50t/d,the effect of feed ore concentration,grinding fineness and magnetic field strength on the separation efficiency were investigated.Due to the high grade tin,which has a certain value to be recovered;however,the single HGMS can't efficiently recovery both tin and iron.Therefore,the combined process of gravity-magnetic separation was used to get the good separation indicators;respectively the grade of gravity concentrate Sn％ is 3.01％,and the recovery rate is 38.22％.The grade of HGMS concentrate Fe is 50.02％,and the recovery rate is 71.42％.关键词
