Resumen de Refractories have a new future with renewable energy
]using solar energy to create such extreme temperatures was no more than a fanciful hope for many. A team of researchers led by Professor Gus Nathan, and including experts at the Commonwealth Scientific & Industrial Research Organization (CSIRO), are investigating the viability of adding solar power to the high-temperature calcination stage of the Bayer process - a way of refining bauxite to produce alumina at around 1,000°C. The research is intended not only to produce high-temperature solar energy, but to sustain it over a long period of time. Industrial Minerals spoke with high-temperature solar expert and researcher Robbie McNaughton of CSIRO, who said that this project would be combining solar technology (in the form of a solar fluidized bed receiver) with natural gas to produce reliable high temperatures.
