Molybdenum is also found in the mineral wulfenite (Pb (MoO4), lead molybdate).
One analysis indicated that a molybdate-based process would be similar to a hexavalent chromium process in terms of labor and capital, more expensive for chemicals and energy, and less expensive for waste processing.
All of the alternatives offer significant improvements in terms of their environmental impact, although chemicals used in some molybdate formulations are toxic to aquatic life.
(As an aside, the mineral scheelite (Ca (WO4, MoO4), calcium tungstate-molybdate) was named after Scheele in honor of his discovery of molybdenum.)
The phosphates are often classified together with the arsenate, vanadate, tungstate, and molybdate minerals.
It is formed when a solution of bichloride of molybdenum is poured into a saturated, or nearly saturated, solution of molybdate of ammonia.
Like the chrome molybdate it would be superfluous as a pigment.
There is likewise obtainable a copper molybdate, by adding neutral molybdate of soda in excess to sulphate of copper.
A more eligible preparation is the molybdate of baryta, produced by mixing solutions of molybdate of potash and acetate of baryta.
A clear malachite green colour, when dried, is produced from molybdate of soda and potash-chrome-alum, or from the molybdate and alum with ammonia.
