BENEFICIATION OF LOW GRADE GRAPHITE ORE OF EASTERN INDIA

Flake graphite is assumed to be derived from the fine-grained sediments rich in organic matter. As metamorphic grade increases, carbonaceous material converts to micro-crystalline graphite [1, 3]. Based on the size of the crystal flakes, flake graphite is classified and graded according to their graphitic carbon content and particle size.

Method for producing artificial powder graphite - BILENKO

When grinding pyrolytic carbon, the destruction occurs predominantly along cracks, defects and thin interpore walls, not destroying the elements of crystal structure. Thus, grinding of pyrolytic carbon obtained at the stated temperatures of 2100-2400° C., does not worsen its graphitizing ability, thereby resulting in artificial graphite powder

High-Grade Flake Graphite Deposits in Metamorphic Schist

Crystalline flake graphite can be divided into two main grades: coarse flakes ( 150–850 m in diameter) and fine flakes ( 45–150 m in diameter), which may be further subdivided into fractions 100–150 m, 75–100 m, and 45 m [15–17]. Flakes in the size range of 250–1000 m in diameter demand the highest price [18].
