What is graphite ore processing?

Graphite and diamond are allotropes, both composed of carbon, and are minerals formed by high temperature, high pressure and billions of years of geological movement. Natural graphite ore is a non-renewable resource and an indispensable raw material for today’s global high-tech and cutting-edge products. Therefore, graphite resources are important strategic resources for the country. With the explosive growth of electric vehicles in recent years, the demand for natural graphite in the future industry will also enter a stage of rapid growth. Selecting and developing new mineral processing technology is one of the important ways to protect and fully utilize graphite resources. The following article will introduce you to the application of a grinding and flotation technology in graphite ore processing.

The important basis for measuring the value of flake graphite ore is the size of graphite flakes and the fixed carbon content. The concentrate measurement index produced in the beneficiation process depends on the dissociation mode, dissociation degree and subsequent beneficiation process of the minerals. The dissociation of minerals is mainly achieved through the grinding process. Different grinding processes and grinding equipment have different effects on the stripping and protection of graphite flakes.

In addition to the grinding process, the flotation process also has an important impact on the quality of graphite ore concentrate. After the concentrate is pre-classified, the qualified large flake graphite concentrate is separated in a certain selection operation, which can greatly reduce the loss of large flake graphite and is also the most effective process for protecting graphite flakes. In addition, the use of reagents in the flotation process will also affect the quality of flake graphite concentrate. Therefore, while paying attention to the selection of flotation process, we should also pay attention to the formulation of reagent system.
