1 Graphite ore beneficiation process is to get graphite concentrates from graphite ores. Graphite is formed by crystallized carbon and has two kinds: crystalloid and cryptocrystalline. The crystal of crystalloid graphite is 1 micron and the has low ore grade.
A low grade graphite run-of-mine r.o.m ore from eastern India was studied for its amenability to beneficiation by flotation technique. The petrography studies indicate that the ore primarily consists of quartz and graphite with minor quantity of mica. It analyzed 89.89 ash and 8.59 fixed carbon.
Grade equivalent to 18.5Mt of graphite compared to 114.5Mt at 16.5 TGC and 9 cut-off grade equivalent to 18.6Mt of graphite as at 31 December 2017 and disclosed in the 2017 Annual Report. The Ore Reserves are based on the Mineral Resource estimates as released by the Company on 29 May

Jan 23 2012 Generally the naturally occurring graphite is of low grade so it is not suitable for industrial applications. Froth flotation is commonly used for the concentration of low grade graphite ore. There are mainly there beneficiation method to extracted the high grade graphite including mechanical flotation cell column cell and bulk oil flotation.
May 01 2015 A low grade graphite ore from eastern India was beneficiated by flotation to improve its quality. The ore was composed of 87.80 ash and 8.59 fixed carbon. Primary coarse wet grinding d 80: 186 μm followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate.

The graphite mining processes are mainly gravity separation process froth flotation process electric separation process and the combination process. And froth flotation process is the main graphite ore processing method. Generally 90-97 grade of graphite concentrate can be obtained after the graphite flotation process.
The latest Ore Reserve is based on 37 of the tonnages of the Measured and Indicated Resource Figure 1 and is a 10 increase in tonnages from the Maiden Ore Reserve ASX March 2017 and a 11.2 increase in grade to a spectacular 17.9 TGC making this the highest-grade mineable Ore Reserve of all the reported graphite reserves in East Africa.
This statistic displays the global graphite price from 2011 to 2014 and a forecast up to 2020 by flake grade. In 2016 the price for large graphite flakes is expected to reach 996 U.S. dollars...
