Abstract: Graphite resource is a kind of valuable nonrenewable resource with a wide range of uses,in order to achieve highefficiency and lowconsumption development and utilization of graphite resources,the research and application of grinding and floating process of large scale graphite,fine scale graphite and microcrystalline graphite are summarized,and it also introduced the research and application of collector,frother and regulator(including depressant,pH regulator,dispersant and flocculant),finally the development trend of graphite flotation technology is prospected.

Key words: Graphite, Grinding and flotation process, System of flotation reagents
