赤峰某铜钼矿尾矿中分离长石试验研究

Study on Separation of Feldspar From the Copper-molybdenum Tailings in Chifeng

通过对赤峰某铜钼矿尾矿试样的考查,发现其中的主要矿物为非金属矿物(脉石矿物),占98.99%,金属矿物含量很少,仅占1.01%。试验进行磁选+浮选、全浮选、重选+浮选以及硫酸法与氢氟酸法对比探索试验,确定采用重选+浮选的氢氟酸法,最终获得长石中含K2O 7.34%,Na2O 4.09%,Si O284.66%。

The tailings of the copper- molybdenum mine in Chifeng had been examined and the results showed that the non-metallic minerals（ gangue minerals） accounted for an overwhelming 98. 99 percent while the metal mineral content was only 1. 01%.The beneficiation process used three methods of magnetic- flotation separation,whole flotation separation and gravity- flotation separation. And then a comparison flotation test was made by the condition of sulphate and hydrofluoric. Finally,the feldspar concentration contained K2 O 7. 34%,Na2 O 4. 09%,Si O284. 66% was taken by the method of gravity and flotation process on the condition of hydrofluoric.
