Vanadium is mined mostly in China, South Africa and eastern Russia. In 2022 these three countries mined more than 96% of the 100,000 tons of produced vanadium, with China providing 70%. [61] Fumaroles of Colima are known of being vanadium-rich, depositing other vanadium minerals, that include shcherbinaite (V 2 O 5) and colimaite (K 3 VS 4 ...
Vanadinite is a mineral belonging to the apatite group of phosphates, with the chemical formula Pb 5 (V O 4) 3 Cl.It is one of the main industrial ores of the metal vanadium and a minor source of lead.
Karelianite is an rare mineral, a natural form of vanadium(III) oxide, V 2 O 3. In terms of chemistry it is vanadium-analogue of hematite, corundum, eskolaite, tistarite, bixbyite, avicennite, and yttriaite-(Y). The name comes from Karelia, a region on the Finnish-Russian border. It may be associated with magnesium-rich rocks. [1]
Vanadium minerals are those minerals containing the element Vanadium. Most are either in the sub-categories Sulfides or Vanadates. Most are either in the sub-categories Sulfides or Vanadates. Subcategories
Vanadium is a trace metal that is relatively abundant in the Earth (~100 part per million in the upper crust). [1] Vanadium is mobilized from minerals through weathering and transported to the ocean. Vanadium can enter the atmosphere through wind erosion and volcanic emissions [1] and will remain there until it is removed by precipitation. [1]
Roscoelite is a green mineral from the mica group that contains vanadium. The chemical formula is K(V 3+, Al, Mg) 2 Al Si 3 O 10 (OH) 2. [2] Crystals of roscoelite take on the monoclinic form, and are from the 2/m point group. The appearance is semi transparent to translucent coloured olive brown to green brown. The lustre is pearly.
Cavansite, named for its chemical composition of calcium vanadium silicate, is a deep blue hydrous calcium vanadium phyllosilicate mineral, occurring as a secondary mineral in basaltic and andesitic rocks along with a variety of zeolite minerals. Its blue coloring comes from vanadium, a metal ion. [6]
Vanadium content in ferrovanadium ranges from 35% to 85%. FeV80 (80% Vanadium) is the most common ferrovanadium composition. [3] In addition to iron and vanadium, small amounts of silicon, aluminum, carbon, sulfur, phosphorus, arsenic, copper, and manganese are found in ferrovanadium. Impurities can make up to 11% by weight of the alloy.
