As a unique mineral, graphite also requires unique handling and attention. As the world’s leading specialist for graphite with decades of experience, we can guarantee that the entire value chain comes from one single source – from mining to packaging and delivery of the final product, from technical consulting to the development of ground-breaking innovations for the applications of tomorrow.
Company mines in Europe and Asia not only ensure the secure supply of graphite to our customers, they also maintain a consistent level of raw material quality – a parameter we monitor meticulously. AMG Graphite has its own purification systems in Germany and uses an array of special grinding processes, selected based on the intended application and customer requirements. The latter also governs the choice of packaging unit, whether paper bags, big bags or silo trains.
The majority of the raw materials for AMG Graphite’s products stem from company mines. Thanks to secure raw material sources in Asia and Europe, we can guarantee our customers the highest security of supply paired with consistently high product quality. We extract graphite from underground mines at our company headquarters in Kropfmühl and in Sri Lanka.
In order to enrich graphite as a concentrate, the crude ore is wet extracted and subjected to flotation. This process separates the graphite from other minerals by wet mechanical means to achieve a carbon content of to up to 98 percent. After this graphite has been dewatered, dried and sieved as well as separated into different fractions, the refined raw material is ground to various grain sizes – with some of the graphites going down to sizes of less than 2 micrometres. Various grinding processes also influence the particle morphology, optimise the particle size and give the graphite its desired shape.
