Commercialising alumina refining using solar heat
An Australian research team led by Professor Gus Nathan, Director of the Centre for Energy Technology, at the University of Adelaide have demonstrated for the first time, a novel solar reactor for calcining alumina, a process which typically takes place at around 950C.

Solar thermal energy for lowering emissions in alumina production
Our researchers have found that introducing concentrating solar thermal (CST) technologies to the Bayer alumina process could enable a 29-45% solar share. This would displace the need for natural gas and decrease operating fuel costs.
