  • Wolframite - an overview | ScienceDirect Topics

    Wolframite is the principal and primary ore mineral of tungsten, and commonly associated with the tin ore in and around granite country rocks. Wolframite is an iron manganese tungsten oxide {(Fe.Mn)WO 4} mineral.The mineral crystallizes in monoclinic system with perfect cleavage, and occurs as massive dark gray to brown-black color and submetallic shining luster (Fig. 1.51).

  • Wolframite - Wikipedia

    Wolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives.
