The US Patent Office (USPTO) has VanadiumCorp Resource (TSXV: VRB; FRA: NWN) the approval notification for the US patent for a process for the electrochemical extraction of vanadium from raw materials containing vanadium was delivered. The USPTO is expected to grant patents in the first quarter of 2021.
Inventor Dr. Francois Cardarelli had filed the patent around two years ago under the reference number US 2020/0157696 A1. The patent application is entitled “Metallurgical and chemical process for the extraction of vanadium and iron from vanadium-containing titanomagnetite and vanadium-containing raw materials”. The future patent belongs to VanadiumCorp-Electrochem Process Technology, a wholly owned subsidiary of VanadiumCorp.
Simplified, energy-saving process
In contrast to the common pyrometallurgical extraction method, in which the raw material has to be melted and the vanadium is then extracted from the slag that forms, the new technology uses electrochemical forces to separate the valuable metals or minerals. In a single process step and with significantly less energy, the contained vanadium can be extracted together with products such as iron and titanium oxide. The invention could in particular make the production of the electrolyte for the vanadium redox battery cheaper and more environmentally friendly, which in turn could promote the further spread of the vanadium redox battery to a large extent.
Adriaan Bakker, VanadiumCorp’s Chief Executive Officer, commented, “Strengthening our intellectual property portfolio is an essential part of our business strategy to move forward with our commercialization plans in 2021. Our wholly owned subsidiary VanadiumCorp-Electrochem Process Technology (” VEPT “) stands for an environmentally friendly and efficient extraction of vanadium with all by-products, which is the key to the further development of vanadium redox flow batteries. The new patent grants VanadiumCorp exclusivity in the USA for a period of twenty years from the date of patent application the USPTO is expected in Q1, 2021 “.
VanadiumCorp has filed for patent protection for VEPT in the following jurisdictions:
– European Union [EP 18757453.8]– Canada [CA 3032329 A1]– United States [US 2020/0157696 A1]– Australia [AU 2018/225820]– India [IN 2019/17004662]– South Africa [ZA 2019/00743]
About the VEPT technology
The VEPT process and the VEPT technology were developed in 2017 by Dr. Francois Cardarelli invented to address specific bottlenecks in the vanadium industry. VEPT was jointly developed by Electrochem and VanadiumCorp over the past four years. VEPT was developed as a cost-efficient, environmentally friendly and more productive alternative to conventional pyrometallurgical processes and opens up many new sources of vanadium, such as Calcine waste or steel slag.
In addition, the process offers itself as a process option for the environmentally friendly development of the flagship vanadium project Lac Doré in Quebec, for which VanadiumCorp only recently received a resource in the “measured and indicated” category of 214.93 million tons with a grade of 24, 6% magnetite released. The company’s Lac Doré vanadium project could produce 52.97 million tons of magnetite concentrate containing 1.3 percent vanadium pentoxide (V2O5), 62 percent iron (Fe) and 8.7 percent titanium dioxide (TiO2). This would be the equivalent of 1.49 billion pounds of vanadium pentoxide.
The in-house sulfation cooker built by Electrochem in February 2017 with a capacity of up to 300 kg / month has already made it possible to test many different raw materials provided by numerous global manufacturers of special steel, primary vanadium, hematite and vanadium-containing titanium magnetite “VTM”. The reduced carbon footprint and the maximum recovery of all metals contained are significant advantages of VEPT compared to the polluting extraction methods currently used in the mining industry. Metals recovered at the same time as VEPT include vanadium pentoxide, vanadyl sulfate, iron (II) sulfate heptahydrate, silicon dioxide and titanium hydrolyzate. All of these products are in high demand and have a very good market forecast.
VanadiumCorp owns the subsidiary VanadiumCorp-Electrochem Process Technology “VEPT” to 100 percent. The company is driving the commercial development of the technology and aims to establish it as a green alternative to extracting vanadium, iron, titanium and silicon dioxide from raw materials such as vanadium-containing titanium magnetite, iron ores and other vanadium-containing industrial by-products.
VanadiumCorp’s goal is to become a strategic supplier of renewable vanadium electrolyte for redox flow batteries and other high purity applications that benefit most from all green and low cost vanadium. VanadiumCorp plans to license VEPT worldwide and use VEPT in the development of the 100% owned vanadium-titanium-iron project Lac Doré. Lac Doré is adjacent to Blackrock Metals Inc.’s property. Blackrock is already licensed to operate a mine and mill to produce a vanadium-rich magnetite concentrate product. However, Blackrock’s business plan is based on conventional extraction processes.
With its Lac Doré project in mining-friendly and geopolitically stable Québec, VanadiumCorp offers investors leverage on vanadium, titanium and iron. Through the unique combination of environmentally friendly extraction technology and a large primary vanadium resource, VanadiumCorp could benefit from a strong vanadium market in the future, driven by the growing demand from the Chinese steel industry and the rapidly growing use of vanadium in sustainable energy storage for applications in residential and industrial applications Applications is driven. Nearby infrastructure includes a 161 kV hydropower plant with an electricity price of approximately $ 0.02 kWh, the CN railway line, abundant water supply, as well as the local airport and a mining community of over 7,000 in the city of Chibougamau.
