About Wolframite Ore. Wolframite is a black or brown mineral which is the chief ore of tungsten. It consists of a tungstate of iron and manganese. The wolframite ore has a high depletion rate, low grade, coarse grain size, high density, low hardness, easy mud formation, and deep color, which is mainly extracted by the gravity separation process.
