Business Applications

Scavenger-Solutions for all Businesses where Functionalised Materials can be used.

Combined Commercial and Environmental Benefits with market leading Scavenger Technology.

Si-Novation Platform Novel Technology is specifically designed for the customer's application.

Technology Implementation is simple and quick with cost-effective performance.

Product Purification

Remove Impurities to achieve Regulatory and Performance Requirements with no Product loss.

         Pharmaceutical & Bio-tech - metals and organic impurities to < 1ppm or lower; No product loss, No added impurities 

​         Precious Metal Recovery - recover a very high % of the metal value;

​         Electronic Chemicals - Precious Metals and Li, Na, K. Mg, Ca, Fe, Cu etc to <1 ppm or lower

         Performance and Fine Chemicals - cost-effective removal of metals and organic impurities

Precious Metal Recovery

Recovery of Precious Metal & Gold from Product, Process and Waste Streams

         Recovery of Precious Metal & Gold from product, process and waste streams

         Very high metal recovery and selective for the target metal

         Cost-effective and simple processes to implement with low environmental impact; implementation with significant      

         commercial, operational and environmental benefits and on site operation.


       Hydroformylation - Rhodium - For production of acids, aldehydes and alcohols

         Cost effective processes, very high metal recovered, very low residual metal content

​         Hydrosilylation - Platinum - silanes and silicones - >95% Platinum recovery achievable

​         C-C (Suzuki) & C-N (Buchwald-Hartwig) coupling - Palladium & Rhodium >99% metal recovered 

​         Hydrogenations - Pd, Pt, Ru, Rh recovered from product, process, waste streams & catalyst washing

         Oxidations, Rearrangements, Protection/De-protection Pd and Pt >98% recovery

Process, Coating and Washing Streams

Cost effective very high Precious Metal Recovery from acidic, aqueous and organic streams

       Precious Metal Catalysts Manufacture - capture of catalyst residues from process streams

         Gold and Platinum from highly acidic process & washing streams

         Precious Metal recovery from streams generated from pyrometallurgical treatment

         Precious Metal recovery from streams generated from hydrometallurgical treatment

         Pd, Pt and Rh recovery from aqueous plating solutions and washings

         Selective recovery of Palladium in acidic solution with high concentrations of Base Metals 

         Selective recovery of Platinum from reverse aqua regia

         Ruthenium and iridium from an organic waste stream

         Selective recovery of Platinum from high concentrations of Tin, Copper and/or Nickel.

Mining & Refining

Selective Recovery of 

         Precious Metals from mining and refining Precious Metals and Gold

​         Low ppm Precious Metals in the presence of high concentration other metals

​         Low ppm Gold, Palladium and Platinum from Gold processes streams

         Platinum and Palladium from a Silver Refining Solution in nitric acid

         Precious Metals from Nickel/Copper mining and refining streams

         Separation of Copper from Gold streams 

Environmental Scavenger-Solutions

Stricter enforcement and lower regulatory residual levels require more effective Scavengers.

Si-Novation Smart Novel Technology meets these and future regulatory lower levels.

Scavenger Solutions are available for the metals highlighted in blue in the Periodic Table.

Notable - Scavengers for Ni, Cu, Cr and Fe achieving <0.1 ppm 

Solid (Heterogeneous) Green Catalysts

Advantages of Solid Catalysts (over Homogeneous)

         Large reduction in toxic waste

         Simpler Product Isolation and Purification - no washings

         Catalyst recycled and reused     

         Control reactivity through catalyst modification
