Merrill-Crowe/Carbon-in-Pulp an Economic Evaluation

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 plants processing ...
