Graphite flotation in the presence of sodium acetate. Graphite was subjected to flotation in the presence of increasing concentration of sodium acetate. A comparison of graphite flotation with the surface tension, both as a function of the sodium acetate concentration in the aqueous solution, revealed a similar pattern of both relations.
DIVA sintered Spargers are used in processing of minerals like, iron ore, limestone, barites, graphite and coal, by flotation a physico-chemical beneficiation process for enriching minerals. In flotation technology generation of uniform fine bubbles is heart of the process.
FROTH FLOTATION "So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined." The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.

When graphite is in high enough concentrations, these rocks can be mined, crushed to a particle size that liberates the graphite flakes, and processed by specific gravity separation or froth flotation to remove the low-density graphite. The product produced is known as "flake graphite." Graphite From Coal Seam Metamorphism ("Amorphous" Graphite)
This paper reviews the flotation of graphite. First, the natural floatability and surface properties of naturally hydrophobic solids, including mainly graphite, are discussed from a surface-chemical viewpoint. Then, general aspects of graphite flotation are briefly explained.
froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

Froth flotation takes place in a water-mineral suspension. It is used for selectively separating minerals by taking advantage of differences in their hydrophobicity. The surfaces of the graphite particles are hydrophobic (water-repellent) and it is thus very amenable to flotation in water using suitable/selective conditioning reagents.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Martin B. Hocking, in Handbook of Chemical Technology and Pollution Control (Third Edition), 2005. 13.2.1 Ore Beneficiation by Froth Flotation. Froth flotation is used to raise the low mineral concentrations in ores to concentrations that can be more economically processed.

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.
