Tungsten Ore Apt

Ammonium paratungstate, APT is a white crystalline salt of ammonium and tungsten. APT is produced by separating tungsten from its ore. Once the ammonium paratungstate is prepared, it is heated to its decomposition temperature, 600 176C. Left over is WO 3, tungsten oxide.

APT is produced by separating tungsten from its ore. Once the ammonium paratungstate is prepared, it is heated to its decomposition temperature, 600nbspdegC. Left over is WO3, tungsten oxide. At that point, the oxide is heated in an atmosphere of hydrogen, reducing the tungsten to powder, leaving behind water vapor. From there, the tungsten metal powder can be fused into any number of things, from wire to bars to other shapes.

Tungsten ores and concentrates sell on the basis of their tungsten oxide WO3 content. The ore undergoes gravity separation to concentrate it at the mine. A chemical flotation process can remove additional impurities to increase the concentration before shipping. The industry standard for first grade tungsten concentrates is a minimum of 65 WO3.

The ore is concentrated at the mine site until it reaches 65 tungsten oxide WO3 content. Tungsten has a high density so gravity methods separate it from the waste rock. After crushing the ore it passes over shaker tables with water and the lower density materials are the tailings. Magnetic separators can further increase concentrations in some ore bodies.Float cells can also improve the quality by using chemicals.
