摘要
某铁矿石嵌布粒度较细,矿石比较难磨,对其进行精准取样,开展选矿试验研究。试验结果表明,TFe品位24.01%的铁块矿,在-400目90.8%的磨矿细度下,经过"预选-三段磨矿-五段磁选"流程选别,可获得精矿TFe品位55.66%、回收率55.07%的选别指标,选矿比4.209倍。
A certain iron ore embedded granularity is relatively fine, and the ore is relatively difficult to grind. Accurate sampling of iron ore bodies in iron mines is carried out, and mineral processing experiments are carried out.The test results show that TFe grade of 24.01% iron ore,in grinding, granularity-0.037 mm accounts for 90.8%, under such conditions,by implementing the separation process of "pre-selection ore-three sections of grinding ore-five segments of magnetic separation", the iron concentrate TFe grade of 55.66% and recovery rate of 55.07% can be obtained.Mineral dressing ratio is 4.209.
