From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture. A rotary dryer is then used to reduce the moisture content to 1 percent or less. ... dry grinding is sometimes performed to reduce the feldspar to less than 74 µm (200 mesh) for use in ceramics, paints, and tiles.

Grind size, flotation reagents and their dosages, pulp pH and flotation time were the main variables studied in these tests. Unnecessarily fine grinding was tried to be avoided to recover graphite as large flakes as possible. Therefore, grinding was mostly performed in stages. Flotation concentrates with almost 90 % C were obtained.

The flotation behavior of feldspars is essentially determined by their surface condition and thus by the extent of hydrolytic decomposition of feldspar surfaces [6]. The cationic-type collectors, which are most satisfactory for acidic minerals, were used in the flotation of feldspars in the thirties. In 1982, it was found that C 6-14 primary
