BioSulphide® & ChemSulphide®
Our sulphide precipitation technologies use biological or chemical sources of sulphide to selectively remove dissolved metals from mining wastewater.
The process works by adding the sulphide reagent to the wastewater under controlled conditions to precipitate the target metal, forming high-grade solid metal sulphides that can be easily dewatered for sale or disposal. The water can then be discharged safely to the environment or re-used onsite. Recovering the dissolved metals as a commercial grade concentrate eliminates/minimizes waste sludge production.
