摘要

摘要: 采用捕收剂MOH对橄辉岩型钒钛磁铁矿中钛铁矿进行浮选试验,探索MOH、H₂SO₄及水玻璃用量对钛铁矿和脉石矿物浮选分离的影响,在条件试验的基础上,进行钛铁矿浮选开路和闭路试验。结果表明,通过"一粗一扫四精"闭路流程试验,最终获得TiO₂品位为46.94%,回收率为53.87%的钛精矿。产品质量检查可知,钛精矿中MgO含量相对较高,仅满足钛精矿五级品要求。扫描电镜结果表明,钛精矿中存在一定量橄榄石,橄榄石难以抑制导致钛精矿中MgO含量高,进而影响钛精矿的浮选指标。

Abstract: The flotation of ilmenite in the onkilonite of vanadium-titanium magnetite using MOH as the collector was investigated.The effects of dosage of MOH,H₂SO₄ and sodium silicate on separation of ilmenite and gangue minerals were studied.The open and closed circuit experiments for ilmenite flotation were carried out on the basis of condition experiments.The results show that through the closed circuit experiment of "one roughing,one scavenging and four cleanings",the ilmenite concentrate with grade of 46.94% and recovery rate of 53.87% for TiO₂ can be obtained.Production quality inspection shows that the MgO content in the ilmenite concentrate is relatively high and it only meets the requirements for 5th grade of ilmenite concentrate.The SEM results show that there exists a certain amount of olivine in the ilmenite concentrate,which is difficult to be separated and leads to increase in MgO content,eventually affecting the flotation index of the ilmenite concentrate.
