莫桑比克某海滨砂矿中蚀变钛铁矿选矿试验研究

对莫桑比克某海滨砂矿进行了选矿试验研究。结果表明, 在原矿含TiO₂ 35.80%时, 采用湿式磁选-重选-干式磁选联合流程, 可获得钛铁矿精矿Ⅰ产率31.94%、含TiO₂ 46.23%、回收率为41.31%, 钛铁矿次精矿Ⅱ产率38.73%、含TiO₂ 44.57%、回收率为48.30%的试验指标。钛铁矿精矿TiO₂综合回收率达到89.61%。该研究为此类钛铁矿的开发和利用提供了依据。

Mineral Processing Technology for Weathered Ilmenite from Beach Placer in Mozambique

Experimental study was carried out on mineral processing of weathered ilmenite from beach placer in Mozambique. The results show that a combined flowsheet of wet magnetic separation-gravity separation-dry magnetic separation adopted to process raw ore containing 35.80%TiO₂, resulted in ilmenite concentrate Ⅰwith a yield of 31.94%, TiO₂ grade and recovery of 46.23% and 41.43%, respectively, and a secondary ilmenite concentrate Ⅱwith a yield of 38.73%, TiO₂ grade and recovery of 44.57% and 48.30%, respectively. Therefore, the comprehensive TiO₂ recovery attained 89.61%. This study can be referred for exploitation and utilization of semblable ilmenite resources.
