The molybdenum will partially oxidize following emission, and remain relatively stable as an oxide. Roasting operations, at temperatures up to about 700 C, must produce some MoS2 fume since the concentrate material begins to sublime at about 450°C. Probably a portion of these fumes will oxidize following emission.

Tungsten metallurgy is the technology that extracts the tungsten metal from tungsten ore raw materials. In 1781, the Swedish chemist C.W. Scheele separated a new oxide from scheelite and named it tungstic acid. In 1783, the Spanish chemists J.J. Elhuyar and F. Elhuyar, who were brothers, separated tungstic acid from wolframite.
