Tungsten is retrieved from the ore minerals scheelite (CaWO4, calcium tungstate) and wolframite ((Fe,Mn)WO4, ironmanganese tungstate). A significant amount of tungsten is recovered through recycling of scrap tungsten products. Uses. Tungsten is mixed with carbon to make a very strong, very resistant material called tungsten carbide. Tungsten carbide is used to make cutting tools and wear ...
Tungsten is mainly used in the production of hard materials based on tungsten carbide (WC), one of the hardest carbides. WC is an efficient electrical conductor, but W 2 C is less so. WC is used to make wearresistant abrasives, and "carbide" cutting tools such as knives, drills, circular saws, dies, milling and turning tools used by the metalworking, woodworking, mining, petroleum and ...

Large deposit of wolframite and scheelite become a source of an important strategic metal like tungsten. During XRF analysis of tungsten from low grade tungsten ore from Degana, it was ob¬served that there was marked difference in the analytical values of tungsten estimated by different methods. The problem of martrix in the low grade tungsten ore was found which adversely affects the results ...
