Precious Metal Recovery from Refining Streams
At PhosphonicS, our scientists relish the challenge presented by the mining and refining industry to recover value from precious metal containing streams. We specialise in designing simple solutions to complex metal recovery problems using the smartest silica technology to optimise results.
Optimum Value Recovery
Precious Metal Recovery from Refining Streams
Residual precious metals (PGMs and Au) can remain in downstream process liquors, aqueous waste streams and holding tanks long after the primary recovery step is complete. Although concentrations may be low, the value lost at scale can be significant.
Our proprietary scavenger technologies are designed to selectively recover platinum group metals and gold from these challenging streams. With exceptional selectivity over base metals, they capture valuable metals on a solid support that can be easily separated and integrated into existing processes.
Whether used as a polishing step or part of a wider recovery circuit, our solutions help maximise overall metal recovery, reduce losses and ensure the final PPMs of value are not left behind.
Highly Effective Performance
Our Phos series of scavengers are designed to outperform standard solid adsorbents at every concentration of precious metal in your stream.
Best Return on Investment
By recovering additional quantities of precious metals beyond what standard chemical and electrolytic methods can achieve, PhosphonicS maximises your returns from every tonne processed.
Plant Based Solution
From laboratory screening through to permanent plant-scale installation, PhosphonicS supports the complete engineering design and implementation of your scavenging solution.
What Makes PhosphonicS Unique?
Patented Multiple Chelating Site Technology
PhosphonicS uses patented technology for attaching powerful ligands to a silica backbone. Multiple chelating sites enable our products to outperform other solid supported products at every concentration of precious metal in your stream.
Highly Selective for Precious Metals Over Base Metals
PhosphonicS scavengers are highly selective for precious metals over base metals. This selectivity allows mining refineries to recover additional quantities of precious metals from barrens streams that are not cost effective to treat using established metal extraction processes.
Comprehensive Laboratory Testing
We work closely with technical and production teams at precious metal mining refining companies to carry out comprehensive laboratory testing of refinery streams, identifying the best scavenger product and operating conditions for each specific stream.
Full Engineering Support
PhosphonicS supports the detailed engineering design and implementation of a complete scavenging solution, from pilot plant scale through to a permanent installation, depending on your requirements.
