Flaky graphite can be easily purified by flotation due to its high natural hydrophobicity [6,7].Generally, the flaky graphite ore was purified via multi-stage grinding-flotation (as shown in Figure 1a) to prevent the graphite flakes from being destroyed during the following regrinding, and a large amount of middling was naturally produced in the process [8,9,10].

Prominer provides the complete solution of graphite processing plant including crushing, grinding and flotation plant to make natural flake graphite concentrate. For graphite concentrate deep processing for anode material, we can also supply spherical graphite spherical grinding & shaping production system and spherical making test service.

Flotation process include multistage grinding, multistage selection, middlings return in order or concentrated. Multistage process have three form, that is concentrate regrinding, middlings regrinding, tailings regrinding. Crystalloid graphite most use concentrate regrinding process, normally, the recovery ratio can up to around 80%.

The flotation method is a relatively common method for purifying minerals. Since the graphite surface is not easily wetted by water, it has good floatability and is easily separated from impurity minerals. The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate.

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.
