Anthracite is formed basically when organic carbon, derived from ancient swamps, becomes emplaced in the earth's crust and is subject to heat and pressure. Coal type is functional by how heat, pressure and time the formation is exposed to. Anthracite is considered the highest Of coal grades having been exposed to low grade metamorphism. Anthracite is mined from seam deposits. The seam is removed and brought to a “breaker" who processes the anthracite coal to different sizes and removes impurities Our main product is for the iron and steel manufacturing Divided in to Lump for charge, slag foaming, and recarburizer. Anthracite Coal contains more fixed carbon than any other form of coal and the lowest amount of volatile (quickly evaporating) material, giving it the greatest heat value. The most valuable of all coals,. Anthracites are black and have a bright, glassy almost metallic lustre. Hard and brittle.
