摘　　要：采用脉动高梯度磁选机改造南江霞石矿选别流程，可使霞石精矿含Ｆｅ２Ｏ３量由０．４％左右降至小于０．２％，霞石精矿成品率从约５０％提高到７５％以上。Dressing process for Nanjiang nepheline ore can be improved with HGMS. By the new process, Fe_2O_3 Content in nepheline concentrates will be reduced to be less than 0.2% from 0.4% or so, and the concentrates yield is up to be greater than 75% from about 50%.
