Galaxy Graphite Corp. Discovers High Grade, Large Flake Graphite on Buckingham Project, Quebec

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 7, 2013) - Galaxy Graphite Corp. (TSX VENTURE:GXY) (the "Company" or "Galaxy") is pleased to announce that it has received all assay results from its Fall 2012 mapping and sampling program on the Buckingham graphite project in Quebec. One sample taken from the property analyzed for size distribution contains 11.5% Cg, with 54.42% large flakes in excess of 80 mesh.

The work program consisted of mapping and sampling, along with ground geophysics (magnetometer and HLEM). A total of 48 grab samples were assayed with graphitic carbon contents ranging from background to 11.5%. Three large (>1 kg) samples were analyzed for size distribution. The graphite is located in marbles in contact with quartzites and biotite gneiss, and in shear zones within the quartzites. The graphite mineralization closely follows NNW-SSE and E-W controlling structures, which are coincident with EM conductors.

The three samples analyzed for size distribution included one from an extension of an old mining operation (the Dominion mine) (sample YS-65D), and two from newly discovered showings (YS-74 and YS-76). Results are summarized in the following table:
Size distribution analysis
Sample Number
YS-65D YS-74 YS-76 size class
%Cg 11.5 1.8 2.0
% >100 mesh 63.42 37.89 30.25 medium or greater
% >80 mesh 54.42 22.43 30.20 large or greater
% >50 mesh 31.03 11.02 17.31 jumbo

The geophysical program has outlined several conductive trends which appear to coincide with graphitic zones mapped in outcrop, and indicate extensions from the Dominion mine.

Analytical work was performed by Activation Laboratories of Ancaster, ON, using Mineral Liberation Analyser (MLA) technology. The geophysical program was performed by Meegwich Consultants of Temagami, ON, and consisted of a magnetometer survey using a GEM Systems GSM-19 magnetometer and an HLEM survey using an Apex MaxMin I unit. Field mapping and sampling, as well as data compilation and interpretation, were completed by EarthMetrix Technologies of Montreal QC.

A follow-up drill program is now being developed, and will concentrate mainly on extensions of the old mine workings.

Chris Healey, President and CEO of Galaxy, commented, "The results of this field work have clearly demonstrated the potential to discover a graphite deposit on the Buckingham property, with a substantial portion of the graphite being of the high demand large-jumbo flake size."

Preparation of high-purity and low-sulphur graphite from Woxnafine graphite concentrate by alkali roasting

An alkali roasting process, which consists of roasting with caustic soda, water washing and sulphuric acid leaching, has beenfound to be an effective method for graphite purification even at low roasting temperature. With this process, a flotation fineconcentrate containing 87–88% carbon could be purified to about 99.4% carbon when roasted with 25% NaOH at 250
°C andleached by 10% H2SO4solution at room temperature. In addition to the successful removal of silicate impurities, the process wasalso found to be effective to eliminate sulphide impurities. For instance, the sulphur content in the end product could be reduced tobelow 0.05% from 0.6% by the process. Furthermore, the consumption of NaOH can be lowered by using high-grade feed. Whenusing a feed of 95.9% carbon (upgraded by flotation), the NaOH concentration could be reduced to 10% from 25% while the productpurity could reach the same purity level of over 99%.....

Graphene Macromolecules To Transform Plastics.
http://proedgewire.com/graphite-graphene-intel/graphene-macr…

Scientists in Germany led by the Freiburg Materials Research Center (FMF) at the University of Freiburg, have succeeded in combining graphene macromolecules with polymers, potentially transforming the global plastics industry forever. Adding to the Freiburg team are the University of Bayreuth, the Federal Institute for Materials Research and Testing (BAM) in Berlin, and the Fraunhofer Institute for Mechanics of Materials in Freiburg. The project named “FUNgraphen,” has created new carbon macromolecules from graphene plus other carbon composite materials with unique properties. Best of all, their new process promises to be low cost and scalable at an industrial level.

With the usual German efficiency expected, the project is funded by the Federal Ministry of Education and Research, and led by the chemist Prof. Dr. Rolf Mülhaupt, managing director of the FMF. It is coordinated by the FMF and in typical German forward thinking, has the support of an industrial advisory board.

In the new advance, individual layers of carbon atoms, become physically and chemically attached to polymers producing carbon “macromolecules,” giant carbon molecules which are less than a millionth of a millimeter thick but can have widths of more than a hundredth of a millimeter. The result, carbon macromolecules that are far more versatile than the carbon nanoparticles in use today, opening up new potential for the development of sustainable materials and technologies. “They have the potential to vastly improve resource and energy efficiency of plastics,” stated Professor Mülhaupt. “The applications range from printed electronics to printed catalysts with a pore design for the production of fine chemicals with simple catalyst recovery.”

Light, durable, environmentally friendly, and electrically conductive, they are resistant to heat, chemicals, and radiation and are impermeable to gas and liquids. The team dispersed several of these large carbon molecules in water, nontoxic solutions, and plastics to produce concentrated stable dispersions without requiring either binders or dispersing aids. These mixtures can be used to coat surfaces and print conductive carbon films as well as electrically conducting micro patterns. The printed conductive carbon layers are much more mechanically robust than printed indium tin oxide layers. The scientists posit that the new carbon will replace much of the far more expensive indium and palladium used in industry.

So where are the new carbon Macromolecules leading us? Well the teams were successful in mechanically reinforcing plastics and rubber with carbon macromolecules and simultaneously making them electrically conductive, resistant to radiation, and more gas-tight. These substances are interesting candidates for application in antistatic and impermeable fuel tanks and fuel lines, casings that are shielded against electromagnetic interferences, and gas-tight automobile tires for reducing fuel consumption in transportation.

Meanwhile the team at the University of Bayreuth has substantially reduced the cell sizes in foams by adding carbon macromolecules, allowing for the improvement of the thermal insulation properties of foams and the development of new, highly efficient insulating materials. The age of cheap, non-flammable, electric conducting, heat resistant, heat dissipating, plastic is about to dawn it seems. Using graphene with plastics will develop into a major use of graphene ahead, I suspect.
