Depending on the deposit, these tungsten ores have a WO 3 content of between 0.3 and 2.5 percentage by weight. Comminution, grinding, flotation and roasting processes can be employed to increase the WO 3 content to approximately 60 %. The remaining impurities are mostly eliminated by means of digestion with sodium hydroxide.
