Reverse osmosis for cyanide recovery
A project was developed from the conception phase through research and development, plant design, plant fabrication and plant commissioning. Reverse Osmosis technology was implemented to produce two valuable product streams from a cyanide waste stream. The feed stream was the vapour condensate from the cyanide evaporation process. The product streams developed were a concentrated cyanide stream returned to the production facility and a demineralised water stream used for cooling water make-up. The project had both economic and environmental advantages.
