Canada Carbon Provides Early Flow Sheet Results for 50 kg Sample of
Miller Graphite
VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 1, 2014) -
Canada Carbon Inc. (the "Company") (TSX-VENTURE:CCB) is pleased to
provide the initial characterization tests for its Miller Property
lump graphite mineralization.
As previously announced on April 14th, 2014, SGS Laboratories
(SGS) is currently conducting a metallurgical test program on a 50
kilogram composite of the Miller graphite, with a view to
developing a flotation concentration flow sheet which optimizes the
preservation of the crystalline graphite structure, as well as
particle size, in order to maximize the potential economic value of
this high-purity graphite. Once these optimized process criteria
are determined, the scale-up to pilot plant design will
commence.
A first exploratory batch cleaner flotation test confirmed the
excellent metallurgical response of the Miller graphite material.
The results provided below, as reported by SGS, are preliminary
results obtained in a single batch cleaner test. It will also be
determined how each size fraction responds to the
caustic-roast/acid-leach upgrading process, so that we can develop
estimates for a cost/benefit analysis for the economics of that
extra processing.
In addition, further tests are being completed to optimize the
flake size distribution and concentrate grade. Initial results
show:
- The reconstituted head grade of the sample was 43.8% C(t)
- The carbon recovery into a preliminary flotation concentrate
was 98.2%. The grade of this concentrate was 94.1% C(t) based on
the reconstituted head grade from the size fraction analysis.
- The results of the size fraction analysis are presented in the
table below:

- 38.1% of the mass reported to the +80 mesh size fractions at a
combined (weighted average) concentrate grade of 98.6% C(t)
- All size fractions larger than 150 mesh yielded grades of at
least 95.5% C(t)
Executive Chairman and CEO Mr. R. Bruce Duncan stated, "Although
these are preliminary results from our flotation optimization
program, we are already seeing an approximately 50% improvement in
the yield of the largest graphite particle sizes, when compared to
the very basic work conducted by SGS last summer. We will soon have
enough graphite concentrate available to begin shipping samples to
a number of potential end-users for their assessment."
