Study on the Reseparation of Crushed and Grinded Anthracitic Middings of Vietnams Quang Ninh
An approach of further increasing the recovery of clean coal is the re - separation of middling coal. This paper focused on high ash content middling coal coming from Cuaong coal preparation plant in Vietnams Quangninh province, with conducting a test on the re - separation research of middling coal after the crushing and grinding processes.This research included the test of the crushing and grinding, the test of sieving and float - sink, so that the optimum conditions on grinding and flotation process were gained.Furthermore, the applicable parameters and technical indicators were put forward. The results revealed that its quite feasible for the re - separation of middling coal after the crushing and grinding process to recycle the clean coal, with the economic benefits and social benefits to the enterprise.
