Tungsten Concentrate AMERICAN ELEMENTS

Tungsten concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard Concentrate particle

Concentrates International Tungsten Industry Association

Concentrates. Marketable ore concentrates of scheelite and wolframite (hübnerite, ferberite) contain typically 65 70 % WO 3.Off-grade concentrates having lower WO 3 concentrations are seldom on the market and if so, only for a lower price. In fully integrated companies lower grades (6-40% WO 3) are often preferred, because upgrading to high concentrations is mostly combined with a lower

Tungsten Wikipedia

Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tungsten which means "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone. It was identified as a new element in
