Producing and selling flake graphite concentrate
In 2006, China Graphite built a beneficiation plant and began processing ores from third parties and producing flake graphite concentrates. As a result, it has an established historical operating basis on which to base future upgrades. The existing plant adopted a flotation flowsheet incorporating primary grinding, rougher flotation, multiple stages of regrinding on the primary concentrate and multiple stages of cleaning, to produce high-carbon graphite concentrates. Debottlenecking and upgrades completed in 2013 expanded the processing capacity to 0.4 Mtpa. From the historical production records, the graphite grade of concentrate was above 94% TGC and the graphite recovery was over 90%. A second phase of expansion was completed in the third quarter of 2021. After that, the flake graphite concentrates processing plant has been being upgraded continuously. As at the end of 2022, the production capacity is 50,000 tpa flake graphite concentrates. Between 2006 to 2018, the feed ore was provided by third parties. In 2019, the operation began to process graphite ore from its own Mine and reduced reliance on third parties’ ores.
