Abstract
A laboratory process study was conducted on the recovery and separation of minerals from geothermal brines. Methods were developed for recovering iron and manganese hydrated oxide compounds as separate components essentially quantitatively. In addition, lead and zinc values were also removed, essentially quantitatively, as coprecipitated compounds together with the hydrated manganese oxides. Exploratory tests indicated that of the alkaline earth metals present, only barium can be easily recovered from the pre- or post-flash brine by precipitation with sodium sulfate. Sufficient design data were obtained during the course of this investigation to enable construction of a pilot-plant-scale demonstration plant for the recovery of mineral values from brine should this be desired.
