Electrowinning Cell – for safe and easy metals recovery

Generally used with gold and silver-bearing cyanide solutions, our cells have also been used successfully with non-cyanide metal-bearing solutions. We offer cell sizes from 50 to 150ft of cathode equivalent volume, normally ranging from 500 to 2000 applied amps per cell, as shown in the table below.

The gold standard for antibody purification, Protein A affinity chromatography, offers the selective capture of antibodies with great yields, but also poses a threat to the quality of the antibodies. Antibodies and Fc-fusion proteins risk forming aggregates as a consequence of the acidic elution from the Protein A ligands, compromising the potency and safety of the drug.

Selective elution of gold, silver and mercury cyanide from …

 · It was found that cyanide was essential for the efficient elution of both mercury and silver, while gold was found to elute most effectively in hot, low-ionic strength solutions. Therefore, the standard AARL-type elution, which implements a cyanide soak and water elution, results in a lower recovery of mercury and silver from the carbon.
