Merrill-Crowe process

The Merrill Crowe Process is a separation technique for removing gold from a cyanide solution. The solution is separated from the ore by methods such as filtration and counter current decantation (CCD) and is then clarified in special filters

Merrill-Crowe Process

Merrill-Crowe Process. One of the two main processes for recovering gold from pregnant cyanide solution.Before gold can be precipitated with zinc dust, all solids must be removed from the pregnant solution.

Zinc precipitation on gold recovery - ResearchGate

Merrill-Crowe process is used for gold/silver precipitation from dilute sodium cyanide solutions and is favoured for gold cyanide containing high silver concentration.Figure 2: Schematic diagram showing gold deposition of gold onto surface of zinc particle ( Gold metallurgy, 2011). Gold is then recovered in...
