Tungsten (W) Properties, Applications
Most tungsten ores contain less than % WO 3 and ore dressing plants are always in close proximity to the mine. The ore is first crushed and milled to liberate the tungsten mineral crystals. Scheelite ore can be concentrated by gravimetric methods, often combined with froth flotation, whilst wolframite ore can be concentrated by gravity, sometimes in combination with magnetic separation.
