The AlphaSelect^®range of materials are capable of removing trace levels of metal ions such as Cu, Ni and Zn from a range of product streams enabling them to be further upgraded, for example Cobalt Sulphate from a standard to a battery grade product.

Utilising AlphaSelect^®Cu & Fe within solvent extraction bleed streams can allow the overall process to be optimised both for the recovery of copper itself & also for the management of iron within the stream, thereby improving overall current efficiency and ultimately lowering electricity usage.

AlphaSelect^®Cu is a unique technology that can be utilised in the Pregnant Leach Solution of the solvent extraction / electrowinning process to improve the overall economic recovery of copper from the mixed ion stream.

A broad range of AlphaSelect^®materials can be utilised in waste discharge streams to both recover lost value (reduce Copper losses) and ensure environmental compliance (Mercury, Arsenic, Cadmium & Selenium removal) from high volume, low concentration mixed metal ion streams.

A number of the AlphaSelect^®materials are applicable for use in acid mine drainage applications, were valuable metals, such as Copper, can be economically recovered from low quality, mixed metal ion feed streams. The AlphaSelect^®materials can also be used to ensure cost effective environmental compliance during processing.

The patented AlphaSelect^®Cu, advanced ion exchange material, is a functionalised silica that selectively recovers copper ions economically from low quality (low ppm), mixed metal ion streams and produces a high purity (>98%) and high concentration stream (>30g/l) for recovery & reprocessing. It is suitable throughout the whole of copper processing flowsheet.

The AlphaSelect^®Fe is a functionalised silica that selectively removes iron economically from low quality (low ppm), mixed metal ion streams. This allows operators to manage the level of iron within their process streams and significantly improves both the economic and sustainability of their operations.

Ecovyst are developing a silica based AlphaSelect^®Hg material that will enable customers to selectively recover mercury from waste & process streams to improve both product purity and ensures environmental compliance on discharge streams.

Ecovyst are developing a silica based AlphaSelect^®As material that will enable customers to selectively recover arsenic from waste & process streams to improve both product purity and ensures environmental compliance on discharge streams.

Ecovyst are developing a silica based AlphaSelect^®Cd material that will enable customers to selectively recover cadmium from waste & process streams to improve both product purity and ensures environmental compliance on discharge streams.

AlphaSelect^®materials have a high selectivity of specific metal ions over all others that both minimises losses and allows high purity (>95%), high concentration (>30g/l) eluted streams to be recovered.

As the backbone of the AlphaSelect^®materials is a functionalized silica, it does not swell or shrink under varying pH conditions. This increases its mechanical strength over standard polymer resins.

One major benefit of the silica based AlphaSelect^®materials are the rapid kinetics during it’s loading & elution phases. This allows for smaller bed sizes, for similar duties, compared with polymer resins.

The AlphaSelect^®materials produce a high purity, high concentration stream that can be simply re-introduced into the process.

AlphaSelect^®materials are highly resistant to contaminants and coupled with its increased mechanical strength, leads to extended lifespan compared with standard polymer resins.
