Beneficiation by Flotation of feldspar is well established. 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 ores. Dry recovery methods are economically limited to about 17% Al2O3. The problem in feldspar flotation is to recover slime free granular ...

Ground mica also is used in the well-drilling industry as an additive to drilling "muds." The plastic industry used ground mica as an extender and filler and also as a reinforcing agent. The rubber industry uses ground mica as an inert filler and as a mold lubricant in the manufacture of molded rubber products, including tires.

Flotation Cells are provided with openings in the partition plates for by-passing the pulp from cell to coll without the pulp circulating through each hood feed pipe. In normal operation these partition gates are left closed; however, this arrangement is advantageous when large tonnages are fed to the flotation machine.

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
