Molybdenum does not occur free in nature it is usually found in molybdenite ore MoS 2 and wulfenite ore PbMoO 4 Molybdenum is also recovered as a by product of copper and tungsten mining It is a silvery white metal of the chromium group It is very hard and tough but it is softer and more ductile than tungsten It has a high elastic moduluschromium is an element that is found on the period table Chromium can be added with another element or a compound of elements to create a compound but chromium by it self is an element

Vanadium was discovered twice The first time was in by Andrés Manuel del Rio who was Professor of Mineralogy in Mexico City He found it in a specimen of vanadite Pb 5 VO 4 3 Cl and sent a sample to Paris However French chemists concluded that it was a chromium mineralIt is usually nonmagnetic but some specimens show slight magnetism because of the admixture of magnetite with chromite Industrial Uses of Chromite Chromite is the sole source of the metal chromium which is the chrome iron alloy employed in the manufacture of special grades of steel
