more abundant in the manganese rich samples. Generally in the manganese rich samples garnet and epidote become more abundant, particularly if the sample is taken close to a volcanic section.

At present, the grade of raw tungsten ore in the world is decreasing year by year. There are less and less easy to mining wolframite, while refractory scheelite and wolframite scheelite intergrowth ore gradually occupy the main position.
Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten . Well formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator,
Tunsten Ores and Concentrates. Tungsten is an elemental metal with the chemical symbol W. It is found in several compounds and is mined in underground and open pit mines all over the world. China is the top ore producer, with over half of the worlds supply. The primary types of tungsten ores and concentrates are wolframite and scheelite.
As nouns the difference between ore and scheelite is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems whichat the time of the rock's evaluation and proposal for extractionare able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present day economic values while
Wolframite, is an iron manganese tungstate mineral, is a primary ore of tungsten, and is the intermediate between ferberite and huebernite . 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.
