This paper presents an economic study comparing two gold recovery processes, zinc precipitation (Merrill-Crowe) and carbon-in-pulp (CIP). Capital, operating, and gold losses costs from an actual CIP plant study are compared to costs developed from a hypothetical Merrill-Crowe process flowsheet. ' Results indicate an overall economic advantage to CIP over Merrill-Crowe for …

Normal Operation of a Merrill Crowe Filtration Circuit After both filtration stages have been brought up to the normal operating conditions, the various process variables and alarms must be monitored by the operator. The operator is also required to sample and analyse process streams and read local indicators.

The main gold loss in a Merrill-Crowe circuit has a much different source (i.e., it results from incomplete washing of the filter cake on the precipitate presses). DeMent and King's results are based on estimated costs of a CIP and Merrill-Crowe plant, bearing in mind that costs are dependent on the particular characteristics of each ore.

Merrill Crowe Process Flowsheet . In the same vacuum circuit is the DE-OXYGENATOR. This is simply a tank and a pump. The vacuum pulls the pregnant solution through the clarifier to the tank. The pump pulls the solution from the tank and forces it through the FILTER PRESS. The rate that the pump discharges the pregnant solution is controlled.

Merrill-Crowe plant data J.R. Parga, R.Y. Wan, and J.D. Miller Abstract - The direct recovery of precious metals from alkaline cyanide solution is frequently accom­ plished by the well-established Merrill-Crowe process involving zinc-dust cementation. This is particularly true for silver. Plant data from two operations are
