摘要
采用高梯度磁选机分选某重选钽铌锡混合粗精矿,研究了磁场强度、脉动冲次、磁介质及转环转速对该精矿中钽铌和锡分离效果的影响.结果表明,在给矿钽品位 11.65%、铌品位 9.33%、锡品位 19.59%条件下,最终可获得含钽 22.31%、含铌 17.38%、含锡3.22%、钽回收率95.48%、铌回收率92.88%、锡回收率8.20%的钽铌精矿,同时可获得锡品位35.87%、锡回收率91.80%的锡精矿,钽铌和锡得到有效分离.
Abstract
High gradient magnetic separation technique was adopted to separate the(tantalum-niobium)-tin bulk concentrate obtained from gravity separation.The effects of magnetic intensity,pulsating frequency,magnetic rod matrix diameter and rotating speed of ring on(Ta-Ni)/Sn separation efficiency were studied.The test results show that,from the bulk concentrate with grades of Ta,Ni and Sn respectively as 11.65%,9.33%and 19.59%,the final tantalum-niobium concentrate containing 22.31%Ta,17.38%Ni and 3.22%Sn can be collected with the recoveries of Ta,Ni and Sn respectively as 95.48%,92.88%and 8.20%,respectively.Meanwhile,a tin concentrate with Sn grade of 35.87%and Sn recovery of 91.80%can be obtained.The tantalum-niobium and tin minerals can be effectively separated.
