Abstract
The invention relates to methods of production of a silica concentrate from geothermal fluids. More particularly, although not exclusively, the invention relates to the production of a colloidal silica concentrate, colloidal silica or precipitated silica from high temperature geothermal fluids by ultrafiltration to produce size-specific silica colloids and step-wise concentration of silica to avoid precipitation or gelling.
