From Waste to Wealth – Mineral Extraction from Geothermal Brines

"An EXTENDED ABSTRACT is available for download. A full-length paper was not prepared for this presentation. The composition and volume of geothermal fluids in New Zealand offers considerable potential for the extraction of various metals and minerals, as well as being a source of heat energy, steam and gases, and for use in generating electricity. While extracting products from geothermal fluids is technically feasible, positive economics is the key driver for commercial success; however, there is no assessment of this opportunity that identifies simple, cost-effective processing technologies and provides a greater understanding of the economic viability and barriers for implementing such technologies. The methodology that will be used to evaluate the commercial opportunities for New Zealand is discussed.CITATION:Mroczek, E, Simpson, M P, Climo, M and Carey, B, 2015.
