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. Finally, the recovery by flotation of kish graphite, which exists in ...
： Collectors are often used to increase the hydrophobicity of valuable minerals during flotation. Hence, it is necessary to know the forces between them, especially the hydrophobic force, which closely associated with hydrophobic minerals floating, such as graphite, coal, and molybdenite.

Graphite ore flotation processing flow chart. Graphite ore can be divided into crystalline graphite, flake graphite and graphite ore with a variety of gangue. The graphite ore beneficiation process is mainly for the graphite ore with different crystal forms, such as graphite ore, pyrite or mica. It adopts multi-stage grinding multi-stage ...
In addition to flotation, Li et al. investigated the washability of microcrystal mineral graphite using float–sink analysis in terms of granulometry for specific gravity ranging from 1.3 to 2.0 ± 0.1 . The main gangue mineral was quartz in approx. 10% by weight; the recovery of graphite was almost 90 wt% with fixed carbon content 72.29 wt%.
Graphite (/ ˈ ɡ r æ f ˌ aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

For each flotation group, 1 g of graphite powders was dispersed in the glass beaker for 2 min at an agitation speed of 500 r/min. After 2 min, the slurry was transferred into the Hallimond tube and continued dispersion on a magnetic stirrer (400 r/min) for another 1 min. Air was injected into slurry to form flotation bubbles with an aeration ...

In graphite flotation, a variety of nonpolar oils such as kerosene and fuel oil are generally used in combination with frothers such as pine oil or higher alcohol. In many respects, graphite responds to flotation in a similar way to coal or molybdenite. The pH of the pulp is usually adjusted to about pH 8.

Graphite from Canada runs 90-97% carbon and graphite from China 90-96% carbon. Careful control of the floatation methodology can generally improve the purity but floatation cannot reduce the level of "intercalated" mineral matter. The size of the graphite flake is a very important commercial consideration.
