improve graphite grade including physical, chemical and thermal methods [15]. However, Because of nat-ural hydrophobicity of graphite, flotation is the most used technique for its beneficiation [15]. In fact, a survey of literature indicates that graphite was the first mineral to be concentrated by flotation by Bessel Brothers in 1877 [15]

Jan 01, 1991 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

Dec 18, 2019 Generally, it can satisfy the requirement of separating fine coal only through one flotation cycle, however, for flotation of graphite, one flotation operation cannot meet industrial requirements [1–3]. Owing to the low grade of raw graphite (generally, in the range of carbon content 5–15%) and high requirement imposed upon the final grade

Graphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation, both the mechanical flotation

Sep 01, 2019 In graphite ore, sericite is one of the main gangue minerals, and thus it is a major impurity in graphite flotation concentrate . The study of entrainment property of sericite in amorphous graphite flotation revealed that the entrainment of sericite leads to the poor flotation selectivity of commercial microcrystalline graphite ore . Moreover

The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate. A higher grade graphite concentrate can be obtained by flotation. Flotation graphite concentrate grades can usually reach 80% to 90%, using multi-stage grinding; the purity can reach 98%

As far as graphite, a naturally occurring carbon, is concerned, it has natural floatability and can be floated using kerosene, as a collector and pine oil as a frother. Add these during grinding and adjust pH to alkaline (7.5 to 8) domain before flotation. See if this serves your requirement. U. Unterstarm

ConclusionFrom the above observations on high pure graphite preparation, the following conclusions are drawn r About 5% of gangue minerals is dissolved during alkali digestion and enhances the product to 89.3% FC from a feed material containing 85% FC.r The flotation end product containing 98% FC with 97% recovery could be achieved by grinding

Generally, diesel and frother are used as reagents in graphite flotation. With the escalating cost of petroleum products and their negative impact on environment, attempts are made to formulate an eco-friendly single reagent to replace the diesel-frother system without affecting the flotation performance.
