摘要
以白马铁矿选矿厂提质前后的原矿、精矿和尾矿为研究对象,采用化学分析、AMICS等研究手段,对样品进行了多元素、矿物组成和单体解离度分析。研究了白马铁精矿品位提高到59%后,其钛磁铁矿、钛铁矿、脉石含量变化规律,钛磁铁矿单体解离度,Fe的主要损失,钛的变化规律等;钛磁铁矿中存在类质同相元素取代及客晶矿物,客晶矿物中的片状钛铁矿、细针状钛铁尖晶石呈微细粒嵌布的形式是导致提质白马铁精矿的Ti O2含量降低困难的主要原因。
Taking the raw ore,concentrate and tailings from Baima concentrate in Panxi zone as the research object,the chemical elements,mineral compositions and monomer dissociation degree of the samples were analyzed by means of chemical analysis and AMICS.The content of titanomagnetite,ilmenite and gangue,the degree of dissociation of titano-magnetite monomer,the main loss of Fe and change of titanium content were investigated when the grade of Baima iron concentrate was raised to 59%. The main reason for the difficulty in reducing Ti O2 content in the extracted Baima iron concentrate is that the lamellar ilmenite and fine acicular ilmenite spinel present in the form of micro fine inlay.
