Abstract
The aim of this study is to acquire graphite from the ore of 3.21%, a technological process including an open circuit experiment of six grinding and seven concentrating steps is testified and in the final concentrate the graphite with fineness (325-mesh) raise to 82.63%. The fine scaly graphite ore from low-grade mine in Dandong, Liaoning contains quartz, sericite, muscovite, feldspar and other impurities. As the only valuable element in the mineral, graphite with small grain size is closely symbiotic with gangue minerals. The technological process also includes a close circuit flotation experiment using sodium silicate as dispersing agent and depressant agent of gangues and using kerosene as inhibited agent and the final rate rises to 86.32% and recovery rate to 82.50%. This experimental study will provide support and guidance on process of graphite minerals with similar characters.
