Whilst gravity concentration usually allows improved process economics and higher recovery, almost all gold ores are leached at some point in the mineral recovery process. Peacocke & Simpson’s mineral and process testing laboratory is capable of undertaking testwork on heap/column leaching, vat leaching, bottle roll leaching, stirred pulp leaching and pressure attrition leaching.
All leach techniques, bar bottle roll, provide our clients with information on leach kinetics, reagent requirements and consumption rate, dissolved oxygen levels and of course total mineral extraction.
Once again our partnership with APT has taken Peacocke & Simpson a step beyond traditional pulp leaching in stirred cylindrical tanks. Our lab has bench and bulk testing capability for APT TriTank technology, where leach kinetics, dissolved oxygen levels and coarse particle suspension are generally superior to those achieved in cylindrical tanks.
