某含炭难选红柱石矿选矿试验研究

Beneficiation Study of a Refractory Andalusite Ore containing carbon

主要介绍了某含炭难选红柱石矿的工艺矿物学及浮选工艺研究。结果表明,采用浮选脱炭—脱泥—酸性浮选—强磁选常规选别艺流程,在磨矿细度70%-0.074 mm条件下,最终获得红柱石精矿产率7.07%、红柱石矿物含量为91.07%、Al2O3含量为55.72%、Fe2O3含量1.50%的选别技术指标,为该矿的开发利用提供了可行性技术方案。

Study on the mineralogy and the flotation of a refractory andalusite ore containing carbon is described in the paper. An andalusite concentrate with a yield of 7.07% , containing 91.07% andalusite, 55.72% AlE03 and 1.50 % Fe203 , can be obtained by the application of the common flowsheet of carbon flotation - desliming - flotation in acid medium - high intensity magnetic sepa ration at a grinding fineness of 70% - 0.074 ram, providing a feasible technical scheme for the de velopment and exploitation of this andalusite ore.
