摘要: 通过对印度尼西亚某海滨铁砂矿进行矿石性质和可选性研究,查明了该矿石的化学成分、矿物组成、粒度组成、主要铁矿物的单体解离度及矿石的可选性。研究结果表明,有用矿物主要为钒钛磁铁矿,也有少量赤铁矿化磁铁矿和褐铁矿共生,该矿自然单体解离度好。在原矿TFe品位30.52%,磨矿细度-0.074 mm占80.0%,采用1次弱磁选粗选、1次弱磁选精选的条件下,获得了产率45.00%,TFe品位58.04%,回收率86.27%的钒钛磁铁矿精矿。为此类海滨铁砂矿的开发与利用提供了依据。

Abstract: Through experiments on ore characteristics and mineral processing of Ferro sands from Indonesia beach, the chemical composition, mineral composition, size distribution and the main iron minerals liberation degree are identified. The results of processing mineralogy test show that the main metallic minerals are titano-magnetite, and a few hematitized magnetite and limonite are coexisted; and it has a good natural liberation degree. For run-of-mine with TFe of 30.52%, vanadium-titanium magnetite concentrate with the yield of 45.0%, TFe grade of 58.04%, and recovery of 86.27% is obtained under grinding fineness of -0.074mm 80.0% by the flow-sheet of one rough low-intensity magnetic separation and one cleaning low-intensity magnetic separation. This research provides a basis for the development and utilization of beach Ferro resources of this type.

Key words: Beach ferro sands, Vanadium-titanium magnetite, Magnetic separation
