Graphene Star Green Graphite revolutionary processing technology allows mass production of highly conductive graphite at the lowest cost possible.
Only graphite and water are used during the manufacturing process, which is free from any chemical reagents and therefore causes no damage to the environment whatsoever.
The value of the electrical conductivity of graphite is the key parameter of graphite quality and determines its use in various applications. In terms of carbon content, the electrical conductivity of graphite is directly proportional to the value of graphite purity.
Highly conductive properties of graphite in the composition of conductive coatings are the prerequisite for the effectiveness of these coatings.
Examples of such coatings are:
● Lithium battery anodes
● EMI shielding
● Infrared heating coatings
● Various sensors
GS Green Graphite processing technology is a single-stage, environmentally safe process for producing highly conductive graphite, which puts an end to traditional environmentally hazardous chemical methods of graphite purification.
The graphs illustrate the change in the electrical conductivity of graphite with different carbon content after a ten-minute processing of graphite using GS technology.
A significant increase in the electrical conductivity of graphite after processing is a consequence of purification of graphite from contamination.
Processing of graphite with a carbon content of 91.7%, 95% and 99%. The particle size is 100 mesh.

A typical technological scheme of the graphite enrichment process includes several stages of grinding and flotation operations in order to minimize the destruction of graphite flakes and at the same time achieve high graphite recovery.
Typically, this process requires seven grinding stages, six cleaner flotation stages, and two flotation purification stages in addition to a coarser flotation stage to produce 92.15% concentrate.
Therefore, in order to obtain graphite concentrate with a carbon content of 95% with a high degree of extraction (for example, 95%) with a short technological scheme, it is necessary to develop effective flotation and graphite purification processes.
Quality improvement, extraction and reduction of impurities in the product are crucial for the application of graphite. The number of large flakes (+100 mesh) of graphite has been decreasing since 2009 with the increase in the introduction of continuous mining technology in graphite mining operations, and thus, small graphite particles are becoming more dominant in the supply to the concentrator. A large number of grinding and flotation stages led to high costs for graphite enrichment. Therefore, it is very important to effectively reduce the number of graphite flotation stages by using more efficient flotation processes to obtain high-quality products from graphite concentrate while maintaining the flake size and increasing graphite extraction.
The usual technological scheme of the graphite flotation process consists of a traditional jaw crusher, cone crusher, ball mill, rod mill and mechanical flotation cells. It is known that a mechanical flotation cell is inefficient when processing small particles.
The new GS graphite processing technology is based on the hydrodynamic effect of acoustic and cavitation waves in a mixture of water and graphite on graphite particles with variable frequency. At the same time, there is no grinding of graphite particles, since there are completely no forces of impact and grinding on graphite for processing.
This GS technology can be easily integrated into existing graphite enrichment plants to significantly increase the productivity of the graphite enrichment process and improve the quality of the final product.
The performance of the new GS technological scheme can be compared with the performance of traditional at least ten flotation stages.
