Achieve Maximum Efficiency in Precious Metal Recovery

Merrill Crowe Process for Gold and Silver

The Merrill-Crowe process is used to separate gold from the solution formed when cyanide leaching is used on gold ores. Leaching removes precious metals from ore by converting the valuable metals into soluble salts. Once the salts have been washed out and processed, pure metal remains.

WesTech’s process expertise helps recover the valuable liquids and/or solids via inter-stage mixing and state-of-the-art sedimentation. Our solutions include countercurrent decantation (CCD) and screening.
