American Manganese To File Patent Application For Proprietary Process To Produce Electrolytic Manganese Metal From Its Artillery Peak Resources
Added May 20th, 2010 – Vancouver, British Columbia
Larry W. Reaugh, President and Chief Executive Officer of American Manganese Inc., (TSX.V: AMY; Pink Sheets: AMYZF) (“American Manganese” or the “Company”) is pleased to report Kemetco Research Inc. (“Kemetco”) has completed its task to develop a conceptual process for extraction and recovery of high purity manganese metal from the Company’s vast manganese resources at Artillery Peak, Mohave County, Arizona.
The overall process, based on a unique application of commercially available process equipment is deemed to be very robust, energy efficient, uses minimal water and in addition to production of electrolytic manganese metal will also produce a clean, saleable anhydrous sodium sulphate by-product. The energy to recover water and destroy dithionates is balanced with the energy produced by burning of sulphur to produce sulphur dioxide. High energy requirements for these applications were a major challenge facing prior art. Dithionate destruction yields sulphur dioxide which can be recycled to the leaching stage and use of water is minimized thru production of solid tailings which can be returned to worked out areas of the open pit.
The Company has agreed to Kemetco’s recommendation to seek patent protection for this novel innovative proprietary technology which will enable the manganese resources at Artillery Peak to be processed at minimum cost: Kemetco will prepare and submit documents for patent application immediately.
Solid waste products are benign. Overall, the process is judged to be a significant development in hydrometallurgy for production of manganese metal from U.S. domestic resources.
- China controls electrolytic manganese production (EMM) supplying and producing 97.44% of the worlds needs (2.6 billion pounds per year).
- There is no substitution for manganese in steel (total manganese market greater than 30 billion pounds per year, fourth largest traded metal).
- The most critical metal at risk to supply and restriction in the United States. No US production.
- EMM’s greatest uses are upgrading specialty steel 47%, manufacture of aluminum 32% and electronics 14%.
- China has a 20% export duty on EMM and the US has a 14% import duty, world price is $1.33/lb. and US price is $1.68/lb.
- Manganese resources are declining in China.
- Overall manganese market grew at 8% per year to 30 billion pounds up to 2008. EMM market grew at 26% per year from 2003 – 2008 to 2.6 billion pounds per year.
