SUBSTANTIAL SAVINGS IN ENERGY, CAPITAL COSTS AND SPACE
IMPROVEMENT IN TiO2 RECOVERY
MONTREAL, June 13, 2012 /CNW Telbec/ - Argex Mining Inc. ("Argex") (TSXV: RGX) (FSE: ASV) (OTCBB: ARGEF) announced today a milestone breakthrough has been achieved to the iron
recovery circuit at its pilot plant in Mississauga, Ontario where the
patented CTL process is running continuously.
Continued process improvements on solvent extraction for the iron
circuit have increased the iron concentration from 68 gpl to 120 gpl,
significantly reducing the energy consumption and also improving the
recovery of TiO2 by 3%.
These improvements will ultimately find their way into a full-scale
industrial production facility.
Enrico Di Cesare, Chief Operating Officer, VP Technology commented,
"Concentration by evaporation from 120 gpl to 140 gpl, which is the
typical required concentration for the pyrohydrolysis acid regeneration
unit, is much more energy efficient than concentrating from 68 gpl to
140 gpl. This is a major breakthrough for us and substantially saves
energy, capital costs, and space. The iron-rich solution in the form of
ferric chloride is then treated in the acid recovery circuit. Work is
continuing with PRO (Process Research Ortech) to simplify and improve
the CTL process".
The CTL process is a proprietary mineral extraction process that allows
for the production of high purity (99.8% pure) pigment grade TiO2 product, which can be sold at premium prices to the end-users in the
paint, plastic and coating industries.
The process is unique because of its ability to produce high-purity TiO2, Iron and V2O5 through a single process directly from the ore material. The equipment
used in all parts of the process is known and readily available. The
innovation of the process lies in how the equipment is used and on how
the solvents and temperatures are properly balanced. The process
operates at atmospheric pressure, thus avoiding the need to handle
chemicals at very high temperatures.
The process is also environmentally friendly due to its high energy
efficiency, low emissions and its closed-loop design, which uses
relatively low levels of hydrochloric acid that is regenerated after
use. The process produces minimal inert tailings from the La Blache ore
deposit. Ultimately, these tailings could be used by the local
construction industry for raw material.
This breakthrough and all the improvements to date will be incorporated
into the feasibility study to be initiated shortly.
About Argex Mining Inc.
ARGEX MINING INC. is a near-term producer of commodities that the world
needs: Titanium Dioxide, Iron and Vanadium Pentoxide. With a primary
goal of advancing rapidly towards production, Argex has adopted a
simple and low-risk strategy for the scale-up of its proprietary
process that allows it to produce high purity TiO2 directly from run-of-mine material from its 100% owned deposit.
The process is running continuously at the mini-plant in Mississauga,
Ontario. The closed-loop process is environmentally friendly and
produces minimal inert tailings.
Additionally, the Company owns 100% of the Mouchalagane property, which
is a large Labrador Trough iron ore property that represents further
potential upside for the Argex shareholders.
