| Abstract: | 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. |
