CERATIZIT | Production
The manufacturing process of tungsten carbide starts with the mining of the tungsten ore. In the first separation and processing steps a very pure crystallised product, ammonium paratungstate (APT) is produced. Annealing in vacuum then results in the blue tungsten oxide W2O5, annealing in air produces the greenish yellow tungsten oxide WO3.

Tungsten: extraction and processing-Metalpedia
The common tungsten extraction methods are surface (or open pit) mining and sub-surface (or underground) mining, or a combination of both. Modern tungsten processing methods dissolve scheelite and wolframite concentrates by an alkaline pressure digestion, and tungsten can also be recycled from Scrap.

Extraction of Tungsten from Scheelite Ore
Since all tungsten ores are very friable and slime easily, concentration must take place as soon as the mineral has been liberated by either crushing or grinding methods. Regardless of the care taken in the selection of the flowsheet, a certain portion of the tungsten is going to be slimed, both during the mining and the milling process.

History of Tungsten | International Tungsten Industry
History of Tungsten. Tungsten, like all the elements having a higher atomic number than iron (Z>26), cannot be formed by nuclear fusion processes in stars, as is the case for those elements with a lower atomic number, but originates only by neutron or proton absorption of already existing bigger nuclei.
