The first step in the production of tungsten is to enrich tungsten from two minerals wolframite ((Fe, Mn)WO4) and scheelite (CaWO4) through the leaching process. The leaching residue usually contains a certain amount (2–5 wt%) of WO3 which is higher than that in the tungsten ore (generally less than 1 wt%). In addition, the leaching residue may also consist of other …
