The two types of feldspar are soda feldspar (7 percent or higher Na 2O) and potash feldspar (8 percent or higher K 2O). Feldspar-silica mixtures can occur naturally, such as in sand deposits, or can be obtained from flotation of mined and crushed rock

    Different Methods of Beneficiation of Feldspar, Mini

    Feldspar is a valuable raw material in the manufacture of glass, ceramic, fillers, enamel Frits, and welding electrodes. Feldspar is the single most abundant mineral in the earth's crust and is generally associated with other silicate, titanium, and iron minerals. As a result, beneficiation of feldspar is necessary to obtain high
