Preserving Flake Size in an African Flake Graphite Ore

Due to the strong floatability of graphite, flotation is the most commonly used method of graphite beneficiation. Among them, crystalline flake graphite has the best floatability, followed by vein graphite; amorphous graphite has the poorest floatability [ 3 , 6 , 7 , 8 , 9 , 10 ].

Brighton is an experienced Metallurgical Engineer with 21 years of postgraduate experience in the recovery and beneficiation of a wide range of minerals that include PGMs, base metals, gold, phosphates and graphite among others.

Natural Flake Graphite Asbury Carbons

Graphite from Canada runs 9097% carbon and graphite from China 9096% 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.

Coarse Graphite Recovery Success in APT's TriFloat

Laboratory results upon an African medium flake graphite ore produce a very high grade coarse graphite concentrate, demonstrating the capability of the APT TriFloat system. Bench and pilot scale flotation produced a flotation concentrate of over 90%C upon a feed of 2mm, said Peacocke.

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

Graphite Physical Processing ANZAPLAN

Each graphite ore has unique characteristics which need to be adressed in the processing. Therefore it is of crucial importance to determine graphite flake morphology, primary flake size and liberation size. Typical flake graphite deposits are gneissic, i.e. they consist mainly of feldspar, quartz and mica.
