Research on Purification Technics of some Flake Graphite

Abstract:

Graphite is the very important nonmetallic ore that high and new technology development needs. According to the ore property, a purification technics of some flake graphite was studies. Firstly, the experiment researched the primary grinding fineness condition test, its result showed that grade has good and recovery is more high when coarse grinding fineness-200 mesh is 66.4%. Then on the basic of the test, a closed trial was conducted by five-times-regrinding and six-times-cleaning, the experimental results indicated that the grade of graphite (Fixed carbon content) is 89.48%, recovery rate reached 97.42%, separation index is better. Finally, the analysis of products showed that fixed carbon content of +100 mesh, +200 mesh graphite flake is respectively 92.90% and 90.53%, so we can choose the multi-grade graphite product.
