Abstract
Separated geothermal water from production wells at Wairakei, Ohaaki, Kawerau, Ngawha and other less developed fields in New Zealand, contains potentially valuable chemical constituents. In particular, the extraction of precipitated amorphous silica is discussed in terms of its strategic and beneficial value to expanded energy generation in geothermal development, removal of environmentally sensitive constituents and as a marketable commodity in its own right. The prospect of recovering other minerals thereby the full potential of geothermal resources is considered. Expectations regarding high temperature reinjection could be reviewed in consideration of alternative opportunities which have been advanced in recent years.
