What is wolframite used for?
Wolframite is highly valued as the main source of the metal tungsten, a strong and very dense material with a high melting temperature used for electric filaments and armor-piercing ammunition, as well as hard tungsten carbide machine tools.
What kind of rock is wolframite?
1.3. 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)WO4} mineral.
How can you tell wolframite?
Place a magnet on a mineral thought to be wolframite. Wolframite contains iron, making it slightly metallic. Shine a UV light on a mineral thought to be scheelite. Scheelite fluoresces bright white-blue under a UV light if it is very pure, and creamy yellow if it contains molybdenum.
What minerals is wolframite made of?
Wolframite consists of a mixture in varying proportions of the tungstates of iron and manganese, FeWO4 and MnWO4; varieties with dominant iron (Fe:Mn⋜4:1) are called ferberite, and those with dominant manganese (Mn:Fe⋜4:1) are called hübnerite.
Is wolframite rare or common?
Composition, Structure and Associated Minerals: Wolframite is a comparatively rare mineral, and is normally found usually with cassiterite and associated also with scheelite, bismuth, quartz, pyrite, galena, sphalerite, etc.
Why is it called wolframite?

Why is wolframite a conflict mineral?
Conflict Minerals are minerals mined in conditions of armed conflict and human rights abuses, by various armed rebel groups. The profits from the sale of these minerals finance continued fighting in the ongoing wars. These minerals include Cassiterite (tin), Wolframite (tungsten), Coltan (tantalum), and Gold.
What is the chemical name of wolframite?
Wolframite is an iron, manganese, and tungstate mineral with a chemical formula of (Fe,Mn)WO4 that is the intermediate between ferberite ( Fe2+ rich) and hübnerite ( Mn2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals.
What are the magical properties of wolframite?
