The vanadium mineral, roscoelite, was named in honor of Roscoe's work. Vanadium is only found in nature in chemically combined forms. It is extracted from vanadiferous ores, slags and residues and converted into vanadium pentoxide or trioxide. Most pentoxide is converted into ferrovanadium, an iron-vanadium alloy.

The Uravan mineral belt mines produced almost 14 million tons of ore averaging 0.24 percent triuranium octoxide (U 3 O 8) and over 356 million pounds of vanadium oxide. Uranium minerals formed irregular deposits in this area commonly referred to as roll-front uranium deposits. Vanadium typically occurs with uranium in these deposits.

Most early uranium mines were converted from former vanadium or radium mining and processing sites. Since the 1970s, uranium has primarily been mined for use as nuclear fuel. Uranium mining during this period was conducted by physically removing ore from higher-concentration deposits, by either digging an open pit from the surface or by ...

The Discovery of Vanadium. In 1801, the Mexican mineralogist Del Rio discovered a new element similar to chromium and uranium when studying lead ore. Its salts are red when heated in acid, so he called it red pigment. It is actually vanadium. In 1830, the Swedish chemist Nrls．G. Sefström isolated a new element when smelting pig iron.

The fourth class of gold ores comprises the gold-telluride group. The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type.
