MONTREAL, Nov. 8, 2011 /CNW Telbec/ - PRO-OR (TSXV: POI), is pleased to announce that the United States Patent and Trademark
Office (USPTO), the U.S. intellectual property protection organization
affiliated with the United States Department of Commerce has granted a
patent for the innovative technological process for the recovery of
platinum group metal (PGM) from ore and / or concentrates as PGM-rich
used automobile catalytic converters and other.
The upcoming patent will give Pro-Or the rights to exclude others from
making, using, offering for sale, or selling the invention throughout
the United States of America or importing the invention into the USA.
The invention being a process, it also gives Pro-Or the same rights for
the products (PGM) made with the process.
The advantage of the process lies in the absence of important flotation
infrastructure, of energy-intensive smelting and autoclave. The process
converts raw materials into highly soluble chlorinated complex into a
weakly acidic solution with a low energy intake. The process uses
industry standard equipments and chemicals readily available for the
reaction. The complete industrial process comprises steps by which the
majority of reagents used can be recycled, reused and / or sold. The
method includes steps to ensure the removal and safe disposal of
Pro-Or is currently working at its pilot plant with CIR Laboratory to
execute the mass balance project for the PGM recovery process. The CIR
Laboratory chemical analysis will be completed in three phases to
determine the industrial recovery rate of PGM with the current process
settings. This data will lead to the completion of our business case
The potential for PGM recovery from automobile catalytic converters is,
to say the least, massive worldwide. For example, in North America
alone over the last 4 years, an average 17 million new vehicles were
sold each year. These vehicles must be recycled at the end of their
life and the residual value of precious metals may be of the order of a
few hundred dollars per unit.
About the Pro-Or technology
The Pro-Or patented high technology process recovers PGM from ore and
from rich concentrates of PGM coming from the recycling of used
automobile catalytic converters. This process requires a small amount
of energy and is environmentally friendly. The process cycle time is
short, which provides for a significant innovative advantage for this
