Introduction of tungsten rod: The reserves of tungsten resources in the world are abundant, at present, there are more than 20 kinds of tungsten and tungsten minerals. Although tungsten and tungsten minerals have been found more than 20 kinds, but today only wolframite and scheelite have the mining economic value.

The wolframite contains different proportions of iron tungstate and manganese tungstate, which is accounting for about 30% of the total global tungsten resources. If the tungsten iron ore has high iron content, tungsten manganese ore has high manganese content. The color of wolframite changes with the change of iron manganese content, the colors that we usually see are dark grey, reddish brown, brownish black, brown hair and brown iron and other types. Wolframite metal has semi metal luster, brittle and weak magnetism.

The scheelite is a kind of translucent mineral with granular or blocky shape. The color changes with the change of tungsten content, the colors that we usually see are white, gray, yellow, purple, brown, pink, green etc., which has oil gloss or glass luster, accounting for about 72% of the total amount of tungsten resources in the world. Scheelite has luminescence, it is light blue or yellow fluorescence under UV irradiation.

The above is the tungsten rod, molybdenum rods that we usually see, we must be reasonable and care in exploitation.
