Feature and Development of Flake Graphite in Typical Graphite Deposits in China

Graphite is one of the 24 strategic mineral resources in China. It is important non-metallic mineral species. It is calculated the averaging production rate of large flake graphite (>0.15 mm) was 14% basing on flake features, ore recovery rate and mineral recovery rate of typical deposits of China. In the last three years, the production of flake graphite in China has been maintained at 600, 000 to 700, 000 tons. The consuming structure of graphite is gradually being transformed and optimized in China. The consuming ratio of traditional fields are decreasing, such as fire resistance and casting; and the consuming ratio of new fields are increasing continuously, such as new energy and new materials. The large flake graphite is mainly used in the fields of expandable graphite and flexible graphite; the small flake graphite is mainly used in metallurgical materials, battery materials, colloidal graphite, polymer composite materials and other fields.
