/CNW/ - VanadiumCorp Resource Inc. (TSX-V: "VRB") (the
"Company") and Electrochem Technologies & Materials Inc. ("Electrochem") are pleased to
announce that The World Intellectual Property Organization "WIPO" (
www.WIPO.int
) has officially
published the Patent Cooperation Treaty "PCT" of the International Patent Application WO
2018/152628 (A1) on
August 30th, 2018
entitled:
"METALLURGICAL AND CHEMICAL PROCESS FOR RECOVERING VANADIUM AND IRON
VALUES FROM VANADIFEROUS TITANOMAGNETITE AND VANADIFEROUS FEEDSTOCKS
"
The jointly owned "VanadiumCorp-Electrochem" processing technology ("VEPT") describes a novel
chemical process invented by Dr.
Francois Cardarelli
that addresses the recovery of vanadium, iron,
titanium, and silica feedstocks such as vanadiferous titano-magnetite, iron ores and concentrates
such as magnetite and hematite, vanadium containing wastes such as BOF-slags, and other
industrial by-products also containing vanadium.
The process consists to digest the vanadiferous feedstocks into concentrated sulfuric acid. The
exothermic sulfation reaction allows operating quasi-autogenously while producing a sulfation cake
and hence minimizing the energy consumption drastically compared to smelting processing methods
used iron and steel producers. The dissolution of the sulfation cake with minimum amount of water
yields a dense pregnant solution and reduces significantly the water usage compared to the
conventional roasting process utilized by existing primary vanadium producers. After reducing
electrochemically, the pregnant solution is subjected to chilling and crystallization yielding pure
crystals of ferrous sulfate heptahydrate (also named copperas). The process further recovers
titanium by hydrolysis from the iron depleted solution thereby producing a vanadium-bearing
pregnant solution. The further concentration by evaporation and then a sequence of chilling and
crystallization yields vanadyl sulfate as key precursor for the preparation of vanadium electrolyte
(VE) used in vanadium redox flow batteries (VRFB) or for preparing various vanadium chemicals.
"The publication of the PCT for VEPT represents a major milestone for VanadiumCorp-Electrochem
Process Technology. A special thanks to Dr.
Francois Cardarelli
, through his diligent work,
expertise and joint partnership with VanadiumCorp has significantly increased the scope of feedstock
capacity and commercial applicability from VEPT's announced invention and provisional patent
application in
February 2017
. VanadiumCorp is committed to near term commercial demonstration of
VEPT and the publication of the PCT patent application allows for the next phase required for
potential commercialization and global deployment. For vanadium specifically, VEPT addresses the
largest industry challenges relating to price volatility and high carbon footprint in the current vanadium
market. With VEPT, vanadium is recovered directly from virtually any feedstock with high efficiency
and negligible carbon footprint." said
Adriaan Bakker
, CEO and President of VanadiumCorp.
"This milestone was a mandatory step for securing our joint IP with VanadiumCorp and before
initiating the national entry phases for key jurisdictions where negotiations are ongoing with industrial
partners for the optioning/licensing of the technology. Moreover, the novelty and industrial
applicability of the patent pending technology is a perfect addition with our patented iron
electrowinning process aiming for commercial deployment here in
Quebec
and abroad constructing a
fully integrated plant" said Dr.
Francois Cardarelli
, President of Electrochem Technologies &
Materials Inc.
