Concentration The flotation concentrate, once dried, is smelted in an electric furnace at temperatures that may be over 1500o C. Then, a matte which contains the valuable metals is separated from the unwanted minerals that are discarded. After being periodically tapped, air is blown through this matte in the converters with the purpose of removing iron and sulfur. Now the "converter matte" PGM content is higher than 1400 grams per ton. Source: unctad.org
