Analyse og prosesseringstester av Kvinnheradkvartsen
Nordic Mining has been carrying out a comprehensive analysis and test program at Dorfner Anzaplan’s laboratory in Germany. Dorfner ANZAPLAN, is an internationally accredited German laboratory with extensive experience on HPQ processing and analysis.
The Quartz in Kvinnherad is of very high quality that can be processed to extremely pure quartz products. The processing involves various separation methods to remove contaminants, including mechanical separation and acid leaching techniques. Concentrates with a total level less than 15 ppm of impurities has been produced. The total level of alkalis (K, Na, Li) is reduced to 0.3 ppm. This is in the range of ”Iota 6” quartz product which is one of the highest grade products on the world market. Melting tests has also demonstrated that the bubble content in glass products are at an acceptable level.
