Stans Energy Corp. (TSXV:HRE) announced that the Russian Institute of Chemical Technology successfully tested a thorium, radium and fluorine extracting process from Kutessay II RE concentrates.
As quoted in the press release:
The final product of these tests was a 98% pure combined RE Oxide (REO) nitrate solution. From this product, VNIIHT is currently conducting a further study, attempting to selectively extract each of the most valuable REOs: dysprosium, terbium, yttrium, neodymium, europium, and lutetium. Using current rare earth pricing, these six oxides account for nearly 85% of projected Kutessay II revenues.
Stans Energy Corp, President and CEO, Robert Mackay, stated:
The cracking stage is the most crucial step in any rare earth production process, and therefore, the value of VNIIHT’s achievements cannot be understated. Stans is the only HRE Company with a hard rock deposit located outside of China that has a demonstrated ability to effectively, and cleanly remove impurities from its concentrate, attain a high level of recovery, while also producing a very pure, soluble REO nitrate for individual REO separation and RE metal fabrication. Although this process has not yet been implemented in any Kutessay II baseline environmental study or feasibility study, VNIIHT’s engineers are confident that this new, contained method of extracting thorium, radium and fluorine from Kutessay II HRE concentrate will provide both environmental benefits and increased profitability over the historical process. Additionally, I would like to add that VNIIHT’s engineers have designed a new process for creating an improved Kutessay II RE concentrate that will be tested in the coming months. Their stated goal is to obtain a minimum RE recovery of 80% from the mine to RE concentrate stage, using new flotation reagents.
