GREENLIGHT RESOURCES INC. (TSX
VENTURE:GR)(OTCBB:PRZCF)(FRANKFURT:PH0) is pleased to announce that
tests have been completed to confirm the validity of the Silchlor
chlorination process in extracting economic minerals from the
Company's Brazil Lake lithium concentrate material. The patented
Silchlor Cyclic Vacuum Chlorination Process technology assessment
report verifying the process was completed by an independent
qualified person. GreenLight retained Dr. Ian Flint of Halifax, NS
to independently confirm if this technology could be applied to the
extraction of economic minerals from the Brazil Lake Lithium and
rare metals project.
Confirmation tests were successfully conducted for the digestion
of the lithium pyroxene concentrate from the Brazil Lake deposit.
The iron, aluminum and lithium chloride products where produced
under the test conditions claimed by Silchlor. These products can
be converted to oxides or carbonates if required by known chemical
processes. The process also shows promise for the purification of
tantalum, niobium and rubidium. The next stage of development will
be the modification of the vessel design to allow the testing of
larger samples in preparation for pilot plant work.
Dr. Ian Flint managed the assembly of a small scale reactor as
well as supervised its testing and evaluation. The purpose of this
series of tests was to independently confirm the results that
Silchlor, the originator of the technology, achieved on the Brazil
Lake deposit material, and to process a larger sample of material
so that the quality of the products can be assessed.
The process involves chlorination at multiple increasing
temperatures including a vacuum stage to volatize certain
chlorides. Chloride vapors of Si, Al, Fe, Li, Rb, Na and K are
produced using this method. The off-gases of the process are then
cooled to precipitate various chlorides with the final stage being
the production of SiCl4 by passing the gases through water.
The Silchlor carbon-chlorination system has shown good initial
success from prior tests which indicated that a significant amount
of the lithium was removed, along with the aluminum, iron, and
manganese. The significant decrease in the residual products
indicates that a large percentage of the spodumene was chlorinated
along with other metals. The objectives of the Company's bench
testing of the Silchlor Cyclic Vacuum Process include:
-- Demonstrate similar or lower cost profiles as the solar brine process
used to extract Lithium from salt pans in South America and Nevada.
-- Replace conventional hydrometallurgical processes which are expensive
and environmentally unfriendly.
-- Minimize waste product.
-- Reduction in impurities in the initial Lithium Chloride product which
could allow for less complicated procedures to produce high purity
products with increased values.
-- Recovery of additional marketable products in the Spodumene, in
particular Rubidium as well as aluminum chloride and silica
tetrachloride.
Dr. Ian Flint P.Eng., a Qualified Person as defined by NI 43-101
is responsible for the technical information contained in this
release.
