aMES™ Technology – for processing of concentrated brines

The activated Minerals Extraction System, or aMES™ is an innovative process technology that enables the treatment of concentrated brine solutions to recover a range of valuable minerals, reagents and fresh water. The technology utilises a proprietary multi-staged process incorporating novel membrane technology and is based on proprietary IP, incorporating patents, expertise and know-how acquired over more than a decade of intense process development initiatives.

What is aMES™?

  • Next-generation (activated) Mineral Extraction System - aMES™.

  • Technology is suitable for recovery of minerals, reagents and water from aqueous solutions including desalination, industrial and mining water waste streams, particularly concentrated brines.

  • The aMES™ process utilises a range of processing steps involving dewatering, crystalliser and reactor vessels, in a variety of proprietary flowsheets, in order to produce a range of valuable products.

  • Mineral extraction is facilitated by systematically concentrating minerals in brines through a proprietary multi-staged process incorporating the novel use of innovative membranes.
