Zenyatta Ventures Ltd. (TSXV:ZEN) is announced a 97.2% graphite product from rough concentrate.
As quoted in the press release:
In conjunction with Don Hains of Zenyatta, Lakefield metallurgical test work of the Albany graphite material continues to develop a simple concentration and leaching process to produce an ultra-high purity (>99.0% C) graphite product. Again, mineralogical work shows the graphite material to be very simple and contains insignificant amounts of undesirable material. This confirms an earlier mineralogical report prepared by Dr. Andrew Conly, Ph.D. of Lakehead University.
