WOLFRAMITE (Iron Manganese Tungstate)
Wolframite is actually a series between two minerals; Huebnerite and Ferberite. Huebnerite is the Manganese rich end member while ferberite is the iron rich end member. Wolframite is the name of the series and the name applied to indistinguishable specimens and specimens intermediate between the two end members.

Tin, Tungsten, Tantalum
Tin (cassiterite), tungsten (wolframite), and tantalum (coltan) are the minerals collectively referred to as the 3Ts. Tin is a light, easy-to-melt metal mainly found in cassiterite rock. Tungsten is a hard, durable metal with a very high melting point that comes from wolframite—a rock named for its tungsten content.

Wolframite
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.

Timing and tectonic setting of tin mineralization in
Most of the primary tin-tungsten ore deposits in southern Myanmar are typical hydrothermal quartz vein–type, with cassiterite and wolframite as the main ore minerals. Here, we present in situ U–Pb ages of cassiterite and wolframite from nine granite-related hydrothermal Sn–W deposits in southern Myanmar.
Wolframite (Tungsten) Mineral
Wolframite is the principal and primary ore mineral of tungsten and is commonly associated with the tin ore in and around granite country rocks. It consists of quartz dyke type ores and veinlet tungsten ores. And the mineral processing of Wolframite is a combined separating technology that mainly use gravity separation.

New insights into separating wolframite from calcium bearing minerals
Wolframite is often associated with calcium bearing minerals, leading to low grade, while conventional anionic collectors are hard to realize their efficient flotation separation, thus the effective structural modification of cationic collectors provides a new insight into enhancing the comprehensive development of wolframite resources.
