Bauxite

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small Get price

Vanadium

Vanadium was discovered by Andreas.M. del Rio in 1801. He prepared salts from the mineral vanadinite (then called brown lead) but did not isolate the pure metal. Metallic vanadium was first isolated by Henry E. Roscoe in 1867, by reducing vanadium chloride (VCl 3) with hydrogen.) with hydrogen. Get price

FOCUS: Pricing bauxite and alumina

2018/3/6Bauxite plays catch-up Unlike the alumina market, the bauxite industry is yet to reach a consensus on pricing mechanisms, beyond long-term, fixed-price contracts. Further upstream in the aluminium supply chain, spot market volumes are thin and still reflect a minority of the sales book that is not captured by integrated activities or long-term contracts.

Vanadium Preis, Vorkommen, Gewinnung und

Ebenso wie reines Vanadium sind auch Legierungen des Vanadiums mit Gallium, Niob und Zirconium supraleitend. Bei Temperaturen unter 5,13 K zeigt Vanadium, ebenso wie die Vanadiumgruppenmetalle Niob und Tantal, in kleinsten Klmpchen bis 200 Atomen eine bisher nicht erklrte, spontane elektrische Polarisation, wie sie sonst nur nichtmetallische Stoffe aufweisen.

Bayer process

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
