磁黄铁矿与磁铁矿分离研究

Study on the Separation Technique of Magnetite and Pyrrhotite

研究了乌拉特后旗欧布乞铁矿磁铁矿和磁黄铁矿的分离技术,采用阶段磨矿-阶段磁选-二磁精浮选脱硫工艺流程,可得到铁精矿品位63.50%、含硫0.210%的合格铁精矿。

Mineral processing technology to separate magnetite and pyrrhotite in Oubuqi Iron Mine of Urad Back Banner, Inner Mongolia, was studied. Adopting a flowsheet of stage grinding-stage magnetic separation-desulfurization froth flotation of concentrate from secondary magnetic separation, a qualified iron concentrate with an iron grade of 63.50% and with sulfur content of 0.210% can be recovered.
