Feldspar Ore Grinding. The Rod Mill is standard for grinding feldspar ore, producing a granular product with a minimum of slime and fine size material. Grinding is always done to minus 20 mesh on account of market requirements. Feldspar this coarse will float very nicely and if liberation is obtained at this size no further grinding is necessary.

Grinding Media Given - nocowaniepolanczyk.eu. The Feldspar Beneficiation & Flotation Process Flowsheet. The flowsheet illustrated is typical for the average feldspar ore containing quartz, mica, garnet and other iron bearing silicates normally encountered in pegmatites or large dykes of alaskite-granite.
Grinding of the feldspar samples to less than 0.25 mm followed by desliming was optimized in the laboratory, using a ball mill in closed circuit with the screen. Anionic flotation of the iron oxide impurity from the -0.25 + 0.03 mm ground product was successfully conducted using locally produced dodecyl benzene sulphonic acid—rice bran oil/kerosene promoter at pH 3.
