临沂低品位钛矿的矿物组成及铁钛元素的分布状态
|
摘要
采用矿物自动分析系统研究了山东临沂低品位钛矿的矿物组成和铁、钛元素的分布状态.结果表明,TFe和Ti O2品位分别为14.25%和6.68%,矿石中磁铁矿、钛铁矿及榍石含量分别为2.60%,5.40%和8.27%;脉石矿物以角闪石为主,其次是斜长石.矿石中磁性铁含量仅为1.88%,占全铁总量的13.21%;钛在矿石中的分布较分散,其中40.69%分布在钛铁矿中,44.14%分布在榍石中.以榍石和钛铁矿为目的矿物,理论上,选矿时可生产Ti O2品位为41.45%的混合钛精矿,钛精矿产率为13.67%,钛的选矿回收率为84.83%.
The distributions of Fe and Ti, and mineral composition of low-grad titanic ore in Linyi, Shandong, were investigated by a mineral liberation analyzer(MLA). The results show that TFe and Ti O2 contents are 14.25% and 6.68%, respectively. Magnetite, ilmenite and titanite account for 2.60%, 5.40% and 8.27%, respectively. Hornblende is the major gangue mineral, and next anorthose. The content of magnetic Fe is only 1.88%, which accounts for 13.21% in total Fe. Ti distributed in ilmenite accounts for 40.69%, and the other 44.14% is distributed in titanite. When ilmenite and titanite were used as the target minerals in mineral processing, the theoretical Ti O2 grade, recovery rate of titanium and yield of titanium concentrate would be 41.45%, 84.83 and 13.67%, respectively.
