(\"Leading Edge Materials\") or (\"the \"Company\") (TSXV: LEM) (OTCQB: LEMIF) (Nasdaq First North: LEMSE) is pleased to provide results from recent mineral processing test work carried out on samples from the Norra Kärr rare earth element (\"REE\") project in Sweden.  Work was undertaken on the nepheline/feldspar by-product material, as part of a program to capture value add opportunities that Norra Kärr provides beyond REEs.  A Pre-Feasibility Study completed on Norra Kärr in 2015 presented REE as the only economic product but identified a range of opportunities to convert much of the mined material into products for sale while minimizing the environmental footprint of the project.  \n\n\n \n \n\n \nBased on extensive previous testwork, the first stage of mineral processing (beneficiation) for Norra Kärr is magnetic separation, which partitions magnetic (iron-rich) minerals including those carrying REEs from non-magnetic minerals.  Magnetic separation is a chemical free process where material is classified by response to a magnetic field.    \n\nThe non-magnetic minerals at Norra Kärr include nepheline and feldspar, which are highly sought industrial minerals for ceramics, glass manufacture, plastics, cosmetics, paint and building products.  Value is placed on a range of factors that include alkali content, aluminum content and iron content which together determine melting conditions and the degree of sample whiteness.  When added to ceramic and glass products, nepheline lowers the melting point of silica both reducing the amount of energy required for glass production and increasing hardness and durability.  Nepheline is also favoured as a paint additive as it is silica-free, and in Russia is used as a source for aluminum.&...
