摘要
甘肃大滩钛铁矿田是岩浆溶离型单一钛铁矿矿床,以其物质组分简单、规模巨大、品位低为其特点,经过四次选矿实验研究,证明该矿石为易选矿石,采用磁选-浮选工艺流程,回收率可达75.12%,品位(TiO2)48.22%;通过对矿石物质组分及矿物赋存状态研究,为该矿床的可开发利用提供了依据[1].
An ilmenite deposit in Datan of Gansu Province, with characteristics of simple component, huge scale and low grade, is a magma liquation deposit. Four times of dressing tests prove that the useful part of the ore is easy to be separated. Using magnetic\|flotation separation process, the recovery rate can be up to 75.12% and the concentrate grade (of TiO\-2) reaches 48.22%. The research on the ore component and mineral occurrence state of the deposit will provide a basis for its development and utilization.
