Open pit mining method is the widely applied mining technique for graphite all over the world. Zenith has been specialized in mining technology for several decades. We developed complete series of open pit graphite mining equipment for sale, including extraction plant, quarry plant, crushing machine, grinding mill, screening machine, separation equipment, processing plant, flotation machine, classifier etc.
graphite beneficiation method
The great majority of world flake graphite production is crushed and ground and then beneficiated by flotation. Treating graphite by flotation typically requires a series of flotation cells to obtain a purer and purer concentrate. In the milling process, the incoming graphite products and concentrates can be ground before being classified (sized or screened), with the coarser flake size fractions (below 8 mesh, 8-20 mesh, 20-50 mesh) carefully preserved, and then the carbon contents are determined. Air classification using winnowers is also used to capture coarser flake and increase the head grade of feed to be subsequently concentrated.
graphite crushing production line
The big raw graphite are fed to the jaw graphite crusher evenly and gradually by vibrating feeder through a hopper for the primary crushing. After first crushing, the material will transferred to impact graphite crusher or cone graphite crusher by belt conveyor for secondary crush; the crushed materials will then transferred to vibrating screen for separating. After being separated, the crushed graphite parts that can meet standard will be taken away as final products, while the other graphite parts will be returned to impact graphite crusher, thus forming a closed circuit. Size of final graphite products can be combined and graded according to customer’s specific requirement. We can also equip dust catcher system to protect environment.
