Abstract
This paper presents the results of a preliminary evaluation of the potential for recovering by products from geothermal fluids. Over 30 chemical species found in geothermal fluid were systematically evaluated. A hypothetical 50 Mwe power plant, using high salinity fluids, was used as a base for our estimate of mineral values. Our study indicates that Li, B, CO2, Br2, I2, Sr and heavy metals appear to be the most promising minerals to be recovered form geothermal fluids. However, improvement in process technology are still required in order to make the minerals competitive with conventional methods of production.
