Wolframite contains iron, manganese and tungsten and is the main ore mineral of the metal tungsten. It is found at many localities within Cornwall, in veins alongside cassiterite and closely associated with granites. Until the mid-19th century, wolframite was treated just as another impurity mineral or waste product.
Feldspar is a kind of silicate minerals which contains calcium, sodium and potassium, there are many categories of Feldspar including albite, anorthite, etc. Feldspar mining process mainly applying flotation process, and Feldspar mining machines mainly including jaw crusher, ball mill, spiral chute, and concentrating table, etc.

Wolframite is a series of minerals belonging to the isomorphic (Fe, Mn)WO 4 with varied Fe/Mn ratios, for which the floatability changes with its composition. In this work, the effects of composition on floatability were studied using micro flotation, collector adsorption tests, infrared spectroscopy, and X-ray photoelectron spectroscopy (XPS).

The study of magnetic properties of members of the wolframite group indicates that they are paramagnetic minerals. Anisotropy of magnetic susceptibility is characterized by the presence of three principal directions. Two of these directions coincide with the crystallographic axis. The axis of easiest magnetization makes an angle of 8° to …

Ore minerals include wolframite, scheelite, and minor molybdenite. Wolframite commonly occurs as aggregates or exhibits coarse crystals (Fig. 4 e). The scheelite in this stage commonly co-exists with the wolframite as anhedral crystals (Fig. 4 f). In addition, a small number of molybdenite forms in this stage.

What are conflict minerals? "Conflict minerals," as defined by the US legislation, currently include the metals tantalum, tin, tungsten and gold, which are the extracts of the minerals cassiterite, columbite-tantalite and wolframite, respectively. Downstream companies often refer to the extracts of these minerals as 3TG.
