Tungsten: extraction and processing-Metalpedia

Contaminated cemented carbide scrap, turnings, grindings and powder scrap are oxidized and chemically processed to APT in a way similar to that used for the processing of tungsten ores. If present, cobalt, tantalum and niobium are recovered in separate processing lines. Other tungsten containing scrap and residues might require a modified process.

Tungsten processing Britannica

Tungsten ores frequently occur in association with sulfides and arsenides, which can be removed by roasting in air for two to four hours at 800° C (1,450° F). In order to produce ammonium paratungstate (APT), an intermediate compound in production of the pure metal, ores may be decomposed by acid leaching or by the autoclave-soda process.

Tungsten element extraction method – surface mining technique

China is known to provide about 75% of the world's tungsten supply. The mining methods used for tungsten depend on the physical and chemical properties of the mineral, the grade and depth of the ore and the physical form in which it occurs. The common extraction methods are surface mining and underground mining. MINING AND PROCESSING :

Tungsten - British Geological Survey

most important tungsten minerals are the monotungstates, such as scheelite (calcium tungstate, CaWO 4), stolzite (lead tungstate, PbWO 4), and wolframite, which is a solid solution5 or a mixture, or both, of the isomorphous6 substances ferrous tungstate or ferberite (FeWO 4), and manganous tungstate or hübnerite (MnWO 4). In practice, the name wolframite is often used
