  • Extraction of TungstenJXSC Machine

    Nov 01, 2018Tungsten is a widely distributed element, almost found in all kinds of rocks, but its content is relatively low. It is possible to form deposits as commercial ore mining by enriching the geological processes. Tungsten ores are mainly divided into wolframite and scheelite. Wolframite is the most important ore to extract tungsten.
