The unit operations of the Merrill-Crowe process include; solid-liquid separation, clarification, vacuum de-aeration in packed towers, zinc addition and filtration of precipitated gold and silver ...
Merrill-Crowe process As this system demonstrates, pregnant solution is clarified and passed through a deaeration tower where it is deoxygenated by vacuum. Following the deoxygenation process, zinc dust is added to the solution, reducing the precious metals in solution to their metallic state while simultaneously oxidizing zinc.

The Merrill-Crowe process is more applicable to gold ore with a high silver and copper content. Improved silver recovery can be obtained with the Merrill-Crowe process versus the Carbon Adsorption process. The Merrill-Crowe process has three basic steps: 1. De-aeration to prevent gold from re-dissolving. 2. Zinc dust precipitation. 3. Filtration.

Flowsheet develpoment and compasrison for the recovery of he demand for platinum is constantly rising, although some manufacturers have ecovered in a carbon adsorption or merrill crowe circuit lunt weeks, 2005to remove oxygen as part of the merrill crowe process in gold and silver mining.
in the condensate tank which could cause a condensate pump trip and subsequent loss of boiler feedwater. Thus it was decided to model the dynamic behaviour of the condenser and vacuum systems using dynamic simu lation software. The simulation would allow engineers to test the process and control system design and detect
The Merrill-Crowe Precipitation Process, embodying the Simultaneous steps of Pre-Coat Clarification, De-aeration and Precipitation for the recovery of gold and silver from cyanide solutions is now almost universally used throughout the world. It appears in the flow sheets of all new mills and in addition has been adopted by most of the older ...

Merrill-Crowe zinc precipitation is a popular process choice for large-volume gold and silver operations. Although the process involves more steps than the carbon filter process, Merrill-Crowe typically offers more efficient precipitation and higher grade bullion with less operational costs in large-volume operations and operations with high silver-to-gold ratios.
the Merrill-Crowe Process. In order to simulate the vacuum deaerator of the Merrill- Crowe Process, a laboratory procedure was established which allowed de-aeration of the solution to a desired level. Zinc concentration was measured by Atomic Absorption Spectroscopy.
