Potassium feldspar is generally flesh-red, yellow-white, white, or gray; the crystals are often short columnar or thick plate-shaped; glass luster; specific gravity 2.56; Mohs hardness 6; melting point 1290℃. It is mainly used for glass and ceramics, and can also be used to make potash fertilizer.Potassium feldspar ores in nature usually contain a variety of […]

Wolframite is mainly composed of tungsten iron ore (FeWO₄) and manganese tungsten ore (MnWO₄), with high density (about 7.1 g/cm³) and brittleness. Wolframite has a high specific gravity, so generally, gravity separation can obtain a good recovery rate. At the same time, the particle size distribution of wolframite is wide in the natural state, and
