American Manganese Receives South Africa Patent for Manganese Extraction Process
Added July 24th, 2014 – Vancouver, British Columbia
Larry W. Reaugh, President and Chief Executive Officer of American Manganese Inc. (“American Manganese” or the “Company”), (TSX.V: AMY; Pink Sheets: AMYZF; Frankfurt: 2AM), is pleased to report that the Company has received the “Patent No. 2013/01364” from the Republic of South Africa for the Company’s manganese recovery process. This patent is a significant milestone for the Company as the invention has secured another key asset that can be exclusively capitalized. The invention is a technical break-through as it enables the recovery of manganese from a low grade resource with significantly less energy and environmental impact than conventional processing methods. The U.S. Bureau of Mines (USBM) developed the frame work for the process from the 1940’s to 1980 but was never able to make it economically viable. Kemetco Research Inc. successfully completed the process to demonstrate it can compete with other electrolytic manganese metal (EMM), electrolytic manganese dioxide (EMD), and chemical manganese dioxide (CMD) producers in the lower cost percentile.
Along with US Patent No. 8,460,621 B2 and the Chinese patent application (Pending), the patents describe key details of how manganese can be recovered from a low grade resource with the following key advantages:
• Low energy requirement.
• Low water use.
• Robust process with a unique assembly of commercially available equipment.
“The hydrometallurgical process developed by the Company is capable of producing high purity electrolytic manganese dioxide (EMD) and chemical manganese dioxide (CMD) critical for improving performance and safety of high tech lithium ion batteries. The invention by-passes steps known to introduce metallic impurities when producing these materials using conventional mining processes,” says Mr. Norm Chow, President of Kemetco Research Inc. He adds, “Conventional mining processes used to produce manganese dioxide for lithium ion batteries are known to contaminate cathode materials with metallic impurities. These impurities can cause internal short circuits after a number of charge/discharge cycles, which will by-pass any protection circuits, and unfortunately can lead to fires or explosions in electric vehicles, laptops, cell phones etc.”
High purity manganese dioxide is combined with lithium carbonate to form the cathode material used in the “spinel” type of high-tech lithium ion rechargeable batteries.
• Management is investigating potential domestic and international opportunities in manganese that have the potential to enhance the Artillery Peak Project.
• Management is investigating potential domestic opportunities in silicon and phosphorus that have the potential to take advantage of emerging technologies for the rechargeable battery industry.
• The Artillery Peak manganese project has the potential to move ahead and develop the resources to become a potential supplier of high purity EMD and/or CMD for the rechargeable battery industry.
• There is no substitute for manganese in steel making (Total manganese market greater than 33 billion pounds per year; fourth largest traded metal).
• Manganese is a critical metal at risk for supply disruptions in the United States as there is no domestic production.
• Electrolytic manganese dioxide and chemical manganese dioxide for the rechargeable battery industry are expected to be the fastest growing segments of the manganese market.
• Tesla’s announcement of the US$ 5 billion lithium ion battery Giga-factory has put the focus on potential suppliers of raw materials for the electric vehicle battery market.
