What Makes PhosphonicS Unique?

PhosphonicS uses patented technology for attaching powerful ligands to a silica backbone. The ability to incorporate multiple chelating sites enables our silica products to outperform other solid supported products, at every concentration of precious metal in your stream.

Advantages of the Phos series

  • More powerful than standard solid adsorbents
  • Designed to only recover precious metals
  • Superior recovery performance

Advantages of silica as a support

  • Highly porous for optimised stream flow
  • Stable in both aqueous and organic media
  • Larger surface area for higher loading

Case Studies

PhosphonicS in the mining refining industry

The extraction of precious metals from mining deposits is a long and complex process requiring significant capital investment.
At PhosphonicS, our work in the mining refining industry has provided a deep understanding that, following the electrolytic refining operations, the key is in the sequential solution and precipitation processes to concentrate, extract and purify precious metals. The refining process gives rise to a barrens stream with high base metal and low precious metal concentrations which is not cost effective to treat using established metal extraction processes.

PhosphonicS scavengers are highly selective for precious metals over base metals. By working closely with PhosphonicS to treat their barrens streams, mining refineries are able to recover additional quantities of precious metals than are available using standard chemical and electrolytic methods thereby maximising their returns from their operations.

Recovering precious metals in the mining refining industry

PhosphonicS works closely with technical and production teams at precious metal mining refining companies to carry out comprehensive laboratory testing of refinery streams in order to identify the best scavenger product and operating conditions for treatment of their particular precious metal containing stream. We then support the detailed engineering design and implementation of a complete scavenging solution, from pilot plant scale through to a permanent installation, depending on customer requirements.
