A Mini Review on Flotation Techniques and Reagents Used in Graphite …
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 …

Natural graphite ore can be easily purified by froth flotation due to its natural hydrophobicity [3,4,5,6]. Flake graphite exhibits a stronger hydrophobicity and is more floatable than amorphous graphite [7,8,9,10,11,12]. As illustrated in Figure 1, graphite beneficiation generally consists of a multistage grinding and flotation process [13,14].
