After several positive updates from the Brantner Oesterreich incinerator bottom ash (IBA) plant (read more here and here), Sepro is excited to announce the release of a collaborative white paper authored by Jonas Boehnke, Andrew Gillis, Gerhard Stockinger, and Bernd Bohle.
The paper, titled “Wet processing of incinerator bottom ash for precious and base metals recovery” includes an overview of metal recovery from IBA, historical challenges in recovering precious and base metals, and the application of gravity concentration to recovering metals in the fine size fraction.
With approximately 20-30% of the IBA feed being in the fine size fraction for the Brantner plant, the Sepro Fine Slag Treatment Plant ends up processing approximately 10,000 tpa with 70% of the precious metals recovered, include gold, copper, and silver.
