High temperature solar electrothermal processing—Zinc from zinc oxide

Edward A. Fletcher and Jon E. Noring

Energy, 1983, vol. 8, issue 4, 247-254

Abstract: We examined the feasibility of using sunlight to reduce the amount of electric power and/or fossil fuel needed to win metals from their ores and other compounds. The uniqueness of highly concentrated sunlight as a source of high-temperature process heat makes it attractive. We also examined, in some detail, ZnO as a candidate substance for exploratory experimental studies. We have mapped out, in temperature-pressure coordinates, the properties of the working substance and the thermodynamic performance of an archetype device as a guide to the temperature-pressure regime in which experimental studies might most profitably be undertaken.
