other cations are present. Flotation by amines occurs readily at slightly alkaline pH (8 – 10) Feldspars These are framework silicates, like quartz. They are desireable ceramic raw materials and separation from quartz and mica is important. Flotation Method Feldspar responds like quartz to anionic collectors so not suitable for separation

For the removal of coloring minerals from feldspar ore the most widely used method is reverse flotation method. Reverse flotation process is generally carried out in conventional mechanical cells. In this study, it was aimed to enrich lowgrade feldspar by using cyclojet flotation cell which was developed as an alternative to conventional cell.

May 01, 2001The principal impurities in some feldspar ores are titanium and iron, which impart color and degrade the quality of the ore. Mineralogical investigations indicate that, while titanium originates mainly from rutile with small amounts of sphene, iron originates mainly from mica minerals. Fatty acids, particularly oleic acid, are extensively used, with reasonable success, in the flotation of

1. A froth flotation process for separating feldspar from quartzfeldspar sands ore consisting essentially of the steps of subdividing said ore to produce at least a fraction having a particle size less than about 1 mm, collecting said fraction and washing the same with water to effect desliming, introducing the washed fraction at a solid concentration of about 2030 wt percent into an aqueous

up a routine procedure for feldspar identification is the development of an adequate concentration method. In mineral industry flotation techniques and electrostatical separation are successfully used for the concentration of feldspars, cf., KIRCHBERG (1955). For large samples flotation is also used on a laboratory scale in many oredressing 4
