The major beneficial mineral was medium flaky graphite which had a much better ability of beneficiation.
Two-stage closed-circuit crushing-one-stage closed-circuit grinding and classification-flotation process of one-stage roughing, two-stage scavenging and ten-stage concentration
The mineral processing test showed that graphite concentrates could be produced through nine-stage grinding, one-stage roughing, one-stage scavenging and nine-stage concentration, with a yield of 14.20%, a fixed carbon content of 92.30% and a recovery of 87.91%. To obtain high-carbon graphite concentrates, the graphite concentrates were treated by wet screening. As a result, the yield and fixed carbon content of -140 mesh concentrates were 3.68% and 95% respectively; those of -140 mesh concentrates were 10.72% and 91.46% respectively.
Thanks to sound technological process and simple reagent system, advanced indices were achieved for the project promising an annual profit of $48 million.
