Overarching AmmLeach(R) Patent Granted in Chile for Method for
Ammoniacal Leaching
Alexander is pleased to report that it has received notification
that its subsidiary, MetaLeach Limited ("MetaLeach"), has been
granted a patent for a Method for Ammoniacal Leaching (Chile patent
number 54.919). This patent forms part of MetaLeach's family of
core AmmLeach(R) technologies and has a standard term of 20 years
from the effective date of 11 July 2008 (being the date of original
filing). The patent is the overarching AmmLeach(R) patent in our
intellectual property portfolio and underpins all applications of
the AmmLeach(R) technology.
Martin Rosser, Chief Executive Officer, said: "We are delighted
with the grant of our patent in Chile for a Method for Ammoniacal
Leaching. Chile is the world's largest producer of copper and a
leader in copper heap leaching. We believe that there are
significant opportunities in the country where AmmLeach(R) has
major benefits compared to conventional acid leaching methods."
The granted Chile patent encompasses methods for leaching one or
more target metals from an ore, the methods comprising the steps
of: curing the ore to be leached through the application of an
aqueous solution of a curing agent, producing a cured ore; leaching
the cured ore at atmospheric pressure through the application of an
ammonium carbonate solution containing free ammonia, producing a
pregnant leach solution; and passing the pregnant leach solution to
a means for metals recovery.
