The Separation Study of Iron-Titan Bearing Minerals

---

An Experimental investigation of the physical separation of iron - titan bearing minerals was carriedrnout. The material used in the expernriments mostly contains ilmenite and rutile. Nowever, microparticlernanalysis has helped to elucidate some associate minerals, i.e, colurnmbite, tantalite, wolframite, monarnzite, xenotime, sphene, aphroside rite, hornblende and malayite. Electrostatic separator cannot sucrncsessfully separate the group of conductor minerals (i.e.ilmenite, rutile,wolframite,columbite,tantalite) from the group of non-conducrntor minerals (i.e.monazite,xenoti-me,sphene,aphrosiderite,hornblende),because most of xenotime and mo-naxite are not existent homogenournsly in the ore. While the selecti-ve separation of those monazite,xernnotime and rutile from ilmenite isrnconsidered easier by using magne tic separation, because each mine ral has different magnetic proper-ties. Itis also shown that heat treatment is effective to increasernthe magnetic property of ilmenite as an effort of improving the separnration. But, excessive heating prornduces reverse effect, in which thernmagnetic property of ilmenite de-creases below its natural magneticrnproperty causing difficult separa-tion. This is due to ilmenite is decomposed into psuedobrookite, rutile and hematite.rn
