Graphite flotation concentrate with particle size under -0.2 mm is worthless. However, after spheroidization and purification, the nature graphite could be widespread used as the battery material and wastewater purification material due to its unique physicochemical characteristics and particle feature. And then the value will be improved obviously.
Natural graphite ores are usually upgraded by froth flotation. However, complex processes with multistage grinding and flotation are required to achieve decent liberation and separation of graphite and gangue minerals. This study reports a short and improved flotation process for fine flake graphite ore by employing a thickening stage. The results indicated that …

The flotation method is widely used for the preliminary beneficiation of aphanitic (microcrystalline) graphite. However, there is limited literature regarding the effects of flotation reagents on the flotation kinetics of aphanitic graphite. In this study, six commonly used flotation kinetic models were used to fit the flotation experimental data of aphanitic graphite.
Malayoğlu et al. (1999) investigated early applications of a collector in the flotation study of Muğla-Milas graphite ore. A fuel oil and kerosene mixture was used as a suppressor reagent while Na 2 SiO 3 was used as a ing agent. The experiments were carried out with basic flotation, three-stage cleaning and a single-stage sweep circuit.
In this study, the aim is to simplify the graphite cleaning process. In order to achieve flotation for graphite effectively, ultrasonic treatment was used as a pre-treatment technique. Flotation tests were conducted using …
In graphite flotation, hydrocarbons like kerosene, fuel oil, paraffin and diesel oil or ionic collectors ... Initially, a few flotation tests were conducted to study the effect of frother type and dosage on the rougher graphite concentrate. Four different types of frother were used in the experiments. The results
To solve the problem of recovery and application of difficult-to-treat kish graphite with a small particle size obtained from metallurgical dust, kish graphite in blast furnace tapping yard dust was effectively enriched and purified by a comprehensive flotation-acid leaching treatment process in this study.
After coal flotation, graphite flotation in the RFC was conducted under the same conditions. Fig. 6 presents the combustible recovery versus gas flux. As can be found, the range of gas flux examined in this study affected graphite flotation significantly. The highest combustible recovery was only 48.9% achieved at the lowest gas flux of 11.10 cm/s.

More relevantly, recent graphite flotation studies [13], [16], [38], [42], [43] also suggested that the droplet size of emulsified kerosene greatly determines the flotation efficiency. For instance, Peng et al. [16] showed that the separation of fine graphite was more efficient with kerosene emulsion of smaller droplet sizes.
The novelty of this review study can be ascribed firstly to its strong resonance with relevancy around graphite beneficiation involving flotation, towards energy storage, prompted …
