Continuous Assaying in a Copper/Lead/Zinc Mineral Flotation Pilot Plant Using In-Stream Analysis Instrumentation

Seven streams of a low tonnage pilot plant operation on Cu/Pb/Zn ore from the Golden Grove Project were continuously assayed using an AMDEL In-Stream Analysis (ISA) system. The ISA instrumentation is briefly described as is the calibration procedure employed. The successful application of this instrumentation in the dynamic environment of a pilot plant operation is discussed. The operational sequence of the Golden Grove pilot plant is outlined along with the original project objectives and how they were achieved by the implementation of ISA. Results for the different complex flowsheets used are discussed, followed by the perceived benefits of installing such equipment in this operation.
