2017/3/1 Nepheline syenite is a rock formed from nepheline and feldspars. Other than typical feldspars, it is formed with silica deficit and so no free crystalline silica occurs in the rock. Typically, the beneficiation consists of crushing and density and magnetic separation. A few typical data of the pure mineral species are listed in Table 2.احصل على السعر
