Matamec on the Path to Precipitating Mixed Rare Earth Oxide
(firmenpresse) - MONTREAL, QUEBEC -- (Marketwire) -- 09/26/11 -- Matamec Explorations Inc. ("Matamec" or the "Company")(TSX VENTURE: MAT) is pleased to announce the successful completion of two bench-scale purification and precipitation tests for the production of a mixed rare earth concentrate from the pregnant leached solution ("PLS"). The PLS is produced in a simple two step process: by magnetic separation and by proprietary leaching of Kipawa's Eudialyte mineralization.
The early purification and precipitation tests have demonstrated the ability to separate the Kipawa rare earths selectively from impurities such as iron and zirconium. It has been shown that over 95% of the iron and zirconium in solution will precipitate and can be removed by adding limestone into the PLS. This purified PLS can then be further treated to completely precipitate out the rare earths from solution. These simple and effective purification and precipitation tests lead towards the production of a high purity mixed rare earth oxide (TREO).
Optimization of the purification and precipitation process is ongoing at SGS Mineral Services in Lakefield, Ontario with the goal of producing a high value mixed rare earth product.
Andre Gauthier, the president of Matamec, comments on the progress to date: "With the purification and precipitation circuit tested in the lab", he says, "the entire Kipawa processing circuit for treating our unique Eudialyte mineralization, from crushing and grinding, magnetic separation, lixiviation, to purification and precipitation, has been demonstrated. This is a major milestone and provides a solid metallurgical foundation for the Preliminary Economic Assessment study, which is due to be completed in October 2011."
Aline Leclerc, V-P Exploration (Geo.) and Eliza Ngai (P.Eng) are Matamec's Qualified Person for this press release.
