Can you guess how important role that mine engineering design plays in mineral processing plant project? Exemplified by Vietnam Kra 800tpd Graphite Ore Dressing Plant Project, Xinhai Design & Research Institute undertook the task of its graphite ore beneficiation test. According to the test report, Xinhai mineral technician designed a flotation process of two stages one close-circuit crushing, one stage one-circuit grinding and classification, one roughing-two scavenging-ten cleaning, which mine
