Title: Recycling and Repurposing of Tailings


Offering to sponsors:

The project offers tailings recycling solutions for reuse/repurposing in mineral processing.


The project uses Solvay Peroxides technology, such as Caros acid units and hydrogen peroxide dosing, to assist end-users in repurposing and recycling their tailings water for their processes. An example is the destruction of cyanide in an environmentally sustainable manner for gold processing streams. Furthermore, by controlling cyanide levels in recycled water recycled back to flotation plants, the end user can maximise gold recovery for sulphide concentrates. There is the added benefit of being able to treat and remove heavy metals in mine water or tailings water.

The technology has been commercially proven.
