Wolframite contains iron tungstate and manganese tungstate in varying proportions, accounting for approximately 30% of the world's total tungsten ore resources. If the iron content is high, it is called tungsten ore, and if the manganese content is high, it is called wolframite. The color of wolframite changes with the change of iron and manganese content. Common colors include dark gray, light reddish brown, light brown black, brown and iron brown. Wolframite has metallic or semi-metallic luster, brittleness, and weak magnetism.
Scheelite is a translucent mineral with a granular or massive shape. The color varies with the change of tungsten content. Our common colors are white, gray, light yellow, light purple, light brown, light red, green, etc. Several types, with grease luster or glass luster, account for about 72% of the world's total tungsten mineral resources. Scheelite is luminescent and emits light blue to yellow fluorescence under ultraviolet light irradiation.
