    A high electric current is passed through pots via the anode The current flows continuously from the anode positive through alumina/cryolite mix to the lining of the pot negative and then onto the next pot Electricity maintains the temperature of the process at about 950°C and enables the alumina to split into aluminium and oxygen . Solar driven alumina calcination for CO2 mitigation and alumina refining with the Bayer process is potentially well suited to the application of CST because it is a highly endothermic process that proceeds at ∼1273 K which is readily achievable with solar tower technology In addition the calcination process is not sensitive to some ingress of air which raises the possibility that direct irradiation of particles may be achievable without the
