It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar

The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).
About 46% of these are mine mill, 8% are other nonmetallic mineral deposit, and 1% are other nonmetallic minerals products. A wide variety of feldspar options are available to you, There are 4,969 feldspar suppliers, mainly located in Asia. The top supplying country or region is China, which supply 100% of feldspar respectively.
