摘　　要：针对菱镁矿矿石中脉石杂质的赋存特点，采用常规反正浮流程，使用Ｎａ２ＣＯ３反浮矿浆调浆，六偏磷酸钠加水玻璃抑制白云石和硅酸盐脉石杂质，并结合浮选前脱泥的工艺，达到了镁钙硅有效分离的目的，较常规工艺提高了浮选精矿指标。The effect of sodium hexametaphosphate and sodium silicate on the flotation of Yinluo magnesiteore is studied.It was found that the synergism of these two depressors isspecially useful in the removal of dolomite and silicate gangue.The size distribution of flotation feed and its mineral composition were also analyzed.It can beseen that pre-desliming by hydrocyclones can improve the flotation effect and decrease the dosage of depressors.
