Froth flotation Wikipedia

OverviewHistoryIndustriesPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti

Graphite Beneficiation Process

Solution to The Graphite Or ProblemA Graphite Froth Flotation FlowsheetGraphite Beneficiation ProcessMost low grade graphite ores are crystalline and respond very well to flotation treatment for graphite recovery. Where a fairly high percentage of the graphite in the comminuted ore is in the +100 mesh it is possible and sometimes desirable to screen out and recover the coarse fractions to market them as such. Coarse flake graphite generally commands a much higher price. On the other hand, where a maximum percentage of graphite in the concentrate is desired, the coarse fraction is recovered a...

Beneficiation of Manganese Ore Using Froth Flotation

Froth flotation is the process generally recommended for the beneficiation of low and medium grade ores because of the floatability characteristics of the manganese. The present work has been taken with waste Manganese ore from Garividi mines (Vizianagaram District).

Froth Flotation Hazen Research

Flotation techniques we have used in addition to the ordinary air-froth type include unusual procedures such as ion, precipitate, and agglomeration flotation using inert gas, air, or in situ gas generation. We have applied dissolved air flotation to special situations and are familiar with various forms of "piggyback" flotation procedures.
