摘要
概括了长石资源特征及其应用,比较了含钾、钠长石与硅酸盐矿物的晶体结构特点与其可浮性的关系。简述了长石中含铁、钛等金属矿物的影响与去除技术,重点归纳了长石与脉石矿物分离的有氟浮选法、无氟有酸法、无氟无酸法3类分选技术,探讨了长石分选过程中含氟废水与酸性废水的危害和处理技术,展望了长石分选技术的发展方向。
The characteristics of feldspar resources and its application were summarized. The relationships of flotability their crystal structure of silicate minerals were compared with feldspar, such as potassium feldspar and sodium feldspar. The influence on properties with metal impurity as well as removing technology of iron, titanium and other metal impurity in the feldspar were introduced briefly. Three methods of separation feldspar from gangue minerals were highlighted, which flotation separation were accomplished by hydrofluoric acid, fluorine-free acid method, and fluorine-free acid-free method. Moreover, harm and disposal of wastewater with fluorine and acid with the processing of feldspar flotation are discussed and developments on the feldspar separation technology are made a prospect in the future.
