Development of process flow scheme on a low-grade calcareous graphite
ABSTRACT The low-grade calcareous graphite ore contains 14.5% Fixed Carbon (FC), 71.82% ash, and 13.68% volatile matter plus moisture content. The primary liberation size, 210 µm was determined by the mesh of grind. In order to upgrade the ore, the sample was ground wet in a rod mill to obtain a coarse product of 210 µm size. It is further subjected …
