FOCUS: Pricing bauxite and alumina Metal

06-03-2018  Bauxite 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.
