(What is cryptocrystalline graphite?)

Cryptocrystalline graphite, also known as earthy graphite or amorphous graphite, is an earthy mineral with a crystal diameter of less than 1 μm, and its specific surface area is between 1-5m2/g. The carbon content of cryptocrystalline graphite ore is generally higher than that of crystalline graphite. Natural pure graphite is very rare, and it is often accompanied by andalusite, mica, kaolin, etc. The carbon content of most cryptocrystalline graphite is 60%-85%, the ash content is between 15%-22%, the volatile matter is between 1%-2%, and the moisture is between 2%-7%. Very few raw ore grades can reach more than 90%.

How is cryptocrystalline graphite distributed?

Cryptocrystalline graphite ores are mainly distributed in contact metamorphic deposits. In fact, the graphite flakes in graphite ore are uneven in diameter. The so-called crystalline graphite ore may also contain cryptocrystalline graphite. When the content is large, it is usually called mixed graphite ore. Cryptocrystalline graphite ore may also contain cryptocrystalline graphite. A small amount of flake graphite with a flake diameter slightly larger than 1 μm.

How to purify cryptocrystalline graphite?

Mineral beneficiation is an important guarantee in the early stage of mineral deep processing. According to the physical and chemical changes in the impurity removal process, the beneficiation and purification methods of cryptocrystalline graphite can be divided into: ① wet purification method, including flotation purification method, acid-base purification method, hydrofluoric acid purification method; ② fire purification method , including chlorination purification method, high temperature impurity removal method.

What are the uses of cryptocrystalline graphite?

Cryptocrystalline graphite is mainly used for pencils, batteries, welding rods, graphite emulsions, ingredients for graphite bearings and raw materials for battery carbon rods, etc. Cryptocrystalline graphite without iron requirements is mainly used for casting materials, refractory materials, dyes and electrode pastes, etc. raw material.
