摘要
山东某钛铁矿矿石性质具有矿物组成复杂、矿物嵌布粒度细等特点,采用"阶段磨矿—阶段选别"的磁选、浮选联合流程对该复杂钛铁矿矿石进行了选矿试验研究,结果表明:对于含Fe 19.48%,TiO29.40%的原矿,可以获得含Fe 66.42%的铁精矿和含TiO245.28%的钛精矿的选矿指标。
A ilmenite ore in Shandong was characterized with complex mineral composition and fine dissemination size. A test for separation of complex ilmenite had been carried out using the ＂stage grinding -stage concentration＂ combination flowsheet consisting of magnetic separation, flotation. The result of test showed that under the condition of the run - of - mine ore of Fe 19.48% and TiO2 9.40%, iron concentrate containing Fe 66.42% and titanium concentrate containing TiO2 45.28% can be obtained respectively.
