    Tungsten Extraction, Extraction Of Tungsten From Scheelite ...

    Ore property: uneven distribution of mineral dissemination particle sizes, and serious mineral mud. Before: The original plant adopted crushing pre-separation-gravity separation-concentrating process, which resulted in the loss of a large amount of fine-grained tungsten minerals, high mineral processing cost and poor mineral processing indexes.

    Tungsten - Wikipedia

    Tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite, and wolframite, lending the element its
