How is tungsten mined and processed

Answered By: Norman Diaz Date: created: Nov 24 2021

Tungsten is usually mined underground. Scheelite and/or wolframite are frequently located in narrow veins which are slightly inclined and often widen with the depth. The ore is first crushed and milled to liberate the tungsten mineral crystals.

What are the properties of tungsten

Answered By: William Green Date: created: Oct 29 2021

Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
