Tungsten and gold are rare non-ferrous mineral products in the world, with low annual output and wide applications, which are mainly used as raw materials for casting ingredients. Tungsten and gold come from a Baisha ore body with a very small ore line. After mining, grinding, water-gravity separation, refining and other processes. Tungsten powder with a grade of more than 95% is obtained, and then the finished product produced by refining and molding in a high-temperature electric furnace is tungsten gold. Melting point of tungsten and gold: 3500℃. At present, tungsten mines are mainly distributed in China and Russian.
