【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、H2SO_4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TiO_2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Mg O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Mg O含量高,进而影响钛精矿的浮选指标。
[Abstract]:The flotation experiment of ilmenite in pyrite type vanadium titanomagnetite was carried out by using collector MOH. The effects of MoHH2SO4 and the amount of sodium silicate on the flotation separation of ilmenite and gangue minerals were investigated. Open circuit and closed circuit tests of ilmenite flotation were carried out. The results show that the titanium concentrate with TiO_2 grade of 46.94 and recovery of 53.87% is obtained through closed circuit test of "one coarse, one sweep and four fine". The product quality check shows that the content of MgO in titanium concentrate is relatively high, which only meets the requirements of the fifth grade of titanium concentrate. The SEM results show that there is a certain amount of olivine in the titanium concentrate, which is difficult to restrain, which leads to the high content of MgO in the titanium concentrate, and then affects the flotation index of the titanium concentrate.
