deposits and occur predominantly in Europe, the Middle East, China and Jamaica. They are generally smaller, poorer quality and have more complex mineralogy (high processing costs) than lateritic deposits. Most bauxite mines produce Direct Shipping Ore (DSO) bauxite as they require no processing before being sent to a refinery.

Conditions within the digester (caustic concentration, temperature and pressure) are set according to the properties of the bauxite ore. Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. At 240°C the

Electrically Calcined Anthracite African Pegmatite

Modern electro-calcination plants utilise direct current over alternating current, as efficiencies are greater despite a power reduction of circa 20%(8). One of the major advantages of electro-calcination is much easier control of heat, and a completely uniform heat distribution. This makes for a completely uniform calcined product, ready for further use. By way of comparison to CA, ECA is ...
