近年来,比較有成效地解决了从复杂的、細粒浸染的伟晶花崗岩黄綠石-锆英石矿石中,浮选回收黄綠石和锆石为貧的混合精矿的任务。在用苛性鈉和苏打灰造成PH值为9.5的矿浆中用油酸(用量达2000克/吨)浮选矿物时,得到了回收率为88.0—92.0％Nb及90.0—95.0％Zr、品位为0.4—0.5％五氧化二铌及1.0—1.2％二氧化锆的黄綠石-锆石混合精矿。
In recent years, more effective solution from the complex, fine-grained granite pyroxene - zircon ore, flotation recovery of pyrochlore and zircon as lean mixed concentrate task. When caused by oleic acid slurry PH value of 9.5 with caustic soda and soda ash (with a capacity of 20 g / t) of mineral flotation, to obtain a recovery of 88.0-92.0% Nb and 90.0-95.0% Zr, grade 0.4-0.5% niobium pentoxide and 1.0-1.2% zirconium dioxide pyrochlore-zircon mixed concentrate.
