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.

Economic Geology of Niobium and Tantalum

Tantalum-niobium placers are commonly derived from pegmatites and occur in their immediate surroundings. The main resource is usually cassiterite with tantalum and niobium as by-products.
