LiB anode material will grow exponentially and it is critical that the west develop an alternative to current graphite purification processes. Benchmark Mineral Intelligence estimates that over 300gWh of LiB manufacturing capacity will be added by 2021.

What remains is a nearly pure carbon material that crystallizes into mineral graphite. This graphite occurs in "seams" that correspond to the original layer of coal. When mined, the material is known as "amorphous graphite."

Here’s a myth buster: There is no lead in pencils. Rather, the core is made up of a non-toxic mineral called graphite. The common name “pencil lead” is due to an historic association with the stylus made of lead in ancient Roman times.

Graphite is a Critical Strategic Mineral The term “strategic minerals” generally refers to mineral ore and derivative products that come largely or entirely from foreign sources that are difficult to replace and that are important to a nation’s economy – in particular to its defense industry.

The purification trials were conducted on graphite concentrates produced by SGS Mineral Services of Lakefield, Ontario. The trials were based on a total product mix and were carried out across the total flake-size distribution (including, large-, medium- and fine-flake size fractions), in order to achieve a full-spectrum sampling of the Coosa ...

The global production of graphite and spherical graphite is currently dominated by China. China uses the mechanical shaping and hydrofluoric acid purification techniques to produce purified spherical graphite.

Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different. This causes almost opposite characteristics in their physical properties.
