摘要/Abstract

摘要： 针对西昌地区某矿山公司生产的钒钛磁铁精矿铁品位偏低、市场竞争力不足的问题，开展了细磨分选提质工艺试验研究。首先对钒钛磁铁精矿进行了化学多元素、XRD及粒度组成与铁分布等工艺矿物学性质研究，然后通过塔磨机、艾砂磨机超细磨磨矿设备比选试验，确定选用塔磨机磨矿。在此基础上，对磨矿产品进一步开展了单一弱磁选、单一淘洗磁选以及弱磁选+淘洗磁选联合分选等工艺分选指标对比，确定采用弱磁选+淘洗磁选联合分选工艺。在塔磨磨矿（-0.045 mm 占 90%），弱磁选磁感应强度 250 mT，淘洗磁选水量 300 mL/s 条件下，获得了产率 87.79%、铁品位 59.33%、铁回收率 95.45% 的高品位钒钛磁铁精矿。试验结果为矿山现场后续流程改造提供了技术依据，也为类似铁精矿提质降杂选矿工艺流程的选择提供了参考。

Abstract: Aiming at the problems of low iron grade and insufficient market competitiveness of vana‐ dium-titanium magnetite concentrate produced by a mining company in Xichang area，experimental re‐ search on fine grinding separation and upgrading process was carried out. Firstly，the mineralogical proper‐ ties of vanadium-titanium magnetite concentrate were studied by chemical multi-element，XRD，particle size composition and iron distribution. Through the comparison and selection test of ultra-fine grinding and grinding equipment of tower mill and Isamill，and tower mill was selected for grinding. On this basis，the separation indexes of single low intensity magnetic separation，single elutriation magnetic separation and combined separation of low intensity magnetic separation + elutriation magnetic separation were compared， and the combined separation process of low intensity magnetic separation + elutriation magnetic separation was determined. The high grade vanadium titanomagnetite concentrate with yield of 87.79%，iron grade of 59.33% and iron recovery of 95.45% was obtained under the conditions of tower mill grinding (-0.045 mm accounted for 90%)，low intensity magnetic separation magnetic induction intensity of 250 mT and washing magnetic separation water volume of 300 mL/s. The test results provide a technical basis for the subsequent process transformation of the mine site，and also provide a reference for the selection of similar iron con‐ centrate upgrading and impurity reduction beneficiation process.
