Solid demand for bauxite and alumina products from customers and Alcoa's (AA) pricing actions and focus on improving operational efficiency are anticipated to have boosted its Q1 earnings.
Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery. This is an electrolytic process, so an aluminium smelter uses huge amounts of electric power; smelters tend to be located close to large power stations, often hydro-electric ones, in order to hold down costs and reduce the overall carbon footprint .
