Hudson Updates Alumina Development Program at Its White Mountain
Anorthosite Project in Greenland
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb 19, 2014) -
HUDSON RESOURCES INC. (the "Company")
(TSX-VENTURE:HUD)(OTCQX:HUDRF) is pleased to announce updated
results for its alumina (aluminum oxide) development program on the
calcium feldspar anorthosite from its White Mountain Project in
Greenland. The objective of this phase of testwork is to produce
smelter grade alumina (SGA) that meets both the chemical purity and
physical specifications required by the aluminum industry.
Hudson, under the supervision of Hudson's consulting
metallurgist, John Goode, P. Eng., has now generated a number of
alumina samples at SGS Lakefield's laboratory facilities in
Ontario. The process involves three key stages, 1) leaching the
anorthosite in hydrochloric acid ("HCl"); 2) sparging the leach
solution with HCl gas to form aluminum chloride hexahydrate ("ACH")
crystals; and 3) calcining the ACH at high temperature to remove
the water and chlorine to regenerate the HCl for recycle and to
produce the final SGA.
Critical to producing a marketable SGA product is ensuring that
the physical properties match or exceed the required specifications
from the aluminum industry, which requires two tonnes of alumina to
produce one tonne of aluminum metal. Two key criteria are:
- The percent of alpha phase alumina typically needs to average
less than 7.5%, and;
- The crystal surface area of the alumina particles (measured by
a test with the acronym "BET"), needs to be between 60 and 80
square metres per gram.
Meeting these parameters is very challenging when using
non-traditional (non-bauxite) ore as the feed material. Hudson has
managed to meet or exceed these key parameters in part due to the
unique nature of the White Mountain anorthosite and its high
solubility.
Through extensive testwork, Hudson has now defined a preliminary
flowsheet and operating parameters that produce an alumina product
with a BET of 74 m2/g and a very low alpha content of 1.7%. The BET
and alpha-alumina tests were conducted at McGill University's
Department of Mining and Material Engineering. The determination of
alpha alumina content used the Australian standard method (AS
2879.3 - 2010) for testing metallurgical alumina.
James Tuer, Hudson's President, stated, "These results are a
very significant step in the development of a flowsheet to produce
smelter grade alumina from our anorthosite. Based on discussions
with key industry players, we know that generating alumina using an
HCl leaching method has proven difficult from a physical property
perspective. Generally, it is relatively straightforward to meet
the chemical purity specifications for SGA. However, meeting the
physical parameters such as BET, low alpha alumina, and larger,
stronger particles has remained elusive. We believe that our
success to date has been due to the unique nature of the White
Mountain anorthosite. As previously reported, we have utilized and
improved upon existing, unpatented aluminum chloride production
processes and we do not require any new technologies to produce a
high quality product."
Metallurgical testwork is ongoing and an economic model is being
developed to further evaluate the potential of White Mountain
anorthosite as a new source of alumina. Currently almost all
alumina is produced from bauxite using the Bayer process, which
produces 2 tonnes of waste for every tonne of ore. Hudson believes
the White Mountain project will have several saleable byproducts
and will not produce significant tailings. Hudson has signed
confidentiality agreements with several companies interested in the
alumina project.
The White Mountain Anorthosite project is 100% owned by Hudson.
The anorthosite has three potential high-value applications which
are being investigated, as follows:
- A new source of feedstock to the high end fiberglass (E-glass)
industry;
- A new source of alumina to supply aluminum smelters
- A new source of filler material. Fillers are extensively used
by the plastics, paints and paper industries
The company is rapidly advancing the E-Glass project with
several Letters of Intent in place. The planned bulk sample test
with a major fiberglass producer is commencing later this month.
The environmental and social impact assessments and technical study
are near completion and the plan is to submit them to the Greenland
Government within the next few months as part of Hudson's
application for a mining permit.
Hudson remains well financed with approximately $2.5 million in
working capital.
