Grinding Flotation Feldspar

Differential Flotation of Some Egyptian Feldspars for ...

An anionic-cationic flotation of two Egyptian feldspar samples, representing Road Ashaab locality of the Eastern Desert of Egypt, was investigated on both laboratory and pilot plant scales. The pegmatites belong to the alkali feldspar granite type, mostly microcline and orthoclase, KAL Si3O8 coarse grained rocks. Quartz, as the main gangue mineral, occurs in two forms as either free …

Dressing of Quartz-Feldspar Ores on the Basis of Selective ...

The process of selective disintegration of hypergenically changed sand in ball and centrifugal mills is studied. The possibility is shown for its effective dressing by transforming feldspars into the finer products with quartz concentration in the coarser fractions. It is established that in grinding, the mechanical activation of surface intensifies flotation separation of the minerals mentioned.

News | Suomen Malmitutkimus

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.

Potassium Feldspar Impurity Removal Process

Weakly acidic flotation has less reagent consumption than weakly alkaline flotation, and the output of potash feldspar is high, and the flotation effect is better. When grinding ore, try to prevent insufficient kinetic energy of particles caused by over-grinding, which makes the target mineral difficult to float. 3.
