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].
Natural graphite is obtained from an abandoned open-cast mine and purified by a simple, eco-friendly and affordable beneficiation process including ball milling and flotation process. Both raw graphite (55 wt %) and its concentrate (85 wt %) were electrochemically tested in order to evaluate these materials as anode materials for Li-ion and Na ...
The first true flotation process was described by the Bessel brothers in a patent from 1877 . Although the brothers Adolph and August co-owned a factory in Dresden, it appears that Adolph (28 September 1835, Wunstorf—12 July 1886, Dresden) was actually the inventor of the process. ... Graphite particles are therefore also anisotropic. Talc ...

The graphite used in battery anodes is typically a form of high-grade purified flake graphite, which has a layered structure that allows for the intercalation of lithium ions during charging and discharging cycles. Since graphite is naturally hydrophobic, flotation beneficiation is the most utilized enrichment technique for upgrading.
In froth flotation, graphite ores are often subjected to a suitable hydrocarbon oil treatment to alter their hydrophobicity, enhance recovery, and /or improve selectivity [13]. ...

The Bessel brothers used oil for flotation of graphite particles but reported in their 1877 patent that the bubbles produced by boiling made the process more efficient (Fuerstenau 2007; Edzwald ...
Results of the release graphite flotation tests illustrate (Fig. 4) that the representative curve for condition 4 is much lower than the curve of condition 1. This means that the use of emulsified kerosene and β-cd (condition 1) as a collector could result in a higher graphite recovery than the un-emulsified kerosene and β-cd (condition 4). ...
The flotation reagents used in this study were acquired from Heilongjiang Luobei Diyuan Graphite Company in China. All the flotation tests were carried out under the following conditions: frother: fusel 300 g/t, collector: diesel 400 g/t, pH 10 (adjusted with lime), quartz and silicate depressant: sodium hexametaphosphate 1000 g/t, pulp solids ...

From 1910 related systems of froth flotation beyond the Elmore's control were introduced in the Americas and elsewhere. As the 20th century progressed, both the scale and scope of flotation treatment increased, so that it became the preponderant mineral-separating method. ...

A novel and simple flotation technique has been developed to prepare high-purity graphite from impure graphite. In this method, a suspension of pristine powdered graphite (PG) is dispersed and stirred in water without adding froth formers or supportive ...
In an 1877 patent, the two brothers Bessel (Adolph and August) of Dresden, Germany, took this "floating" process a step further and added a small amount of oil to the tanks and boiled the mix – an agitation or frothing step – to collect the graphite, the first steps toward the future flotation process. Adolph Bessel received the Wohler ...
In fact, a survey of literature indicates that graphite was the first mineral to be concentrated by flotation by Bessel Brothers in 1877 . Thereafter, considerable advances in flotation were performed making it the economically competitive process to enrich mineral even low grade ore considered as waste [16] .
Fig. 9 a shows that the graphite flotation recovery increased from 97.67% to 99.84% and concentrate grade decreased from 26.32% to 22.87% with an increase in aeration rate from 0.6 to 1.2 L/min. When the aeration rate was in the range of 0.6–0.9 L/min, there were not enough bubbles to load and carry all graphite particles to the froth ...

Reagent types and their dosage for each flotation stage are also illustrated in Fig. 10. The graphite concentrate containing 77.80% total carbon can be obtained with the recovery of 46.68%. 5 Conclusions

Of particular interest, a Bessel patent addresses applying their improved methods to the processing of graphite, now known to be a low-cost source of graphene. Fuerstenau summarizes this patent: "A German patent was issued to Gebrueder [sic, the brothers] Bessel in Dresden, and using only 305 words, this 1877 patent outlined a process for the ...

1. Introduction. Graphite is a natural crystalline allotrope of carbon that is greenish-black and shiny [].K. W. Scheele first chemically characterised graphite in 1779, and A. G. Werner later gave it the term "graphite," which was derived from the Greek word "grapho," which means "I write" [].There are many different physical and structural forms of carbon that exist in nature [].
