    Extraction of Tungsten from Scheelite Ore. Regardless of the care taken in the selection of the flowsheet, a certain portion of the tungsten is going to be slimed, both during the mining and the milling process. In general the ability to recover the slime tungsten means the difference between success or failure of the milling installation and of the preceding mining operations.

    Feb 26, 2014Tungsten is an element with atomic number 84 and symbol W. Tungsten was first identified as a new element in the year 1781 and then it was identified as an isolated element in 1783. This is a hard and rare metallic element which is also called wolfram at times since it is mainly extracted from its ore called wolframite.

    The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
