Batch and locked cycle flotation testwork

Batch Mineral Testing

Batch laboratory scale tests can be carried out to determine preliminary design parameters such as grind size, reagent requirements, flowsheet design and flotation retention time for the economic recovery of the valuable mineral(s).

AMML has extensive experience in the flotation of simple and complex base metal sulphide ores, gold and silver bearing ores, platinum group metals and industrial minerals. The staff has an excellent track record for developing flotation chemical conditions and circuit designs for problematic and complex ores (eg. for sequential Cu-Pb-Zn flotation and reverse flotation). AMML uses several techniques such as controlled potential sulphidisation (CPS) and specific collectors tailored for flotation of base metal oxide and transition ores, including precious metals.

Locked-Cycle Testing

Locked-cycle flotation tests can be undertaken to provide results and data of the metallurgical performance on a continuous circuit. These tests include re circulation of circuit water and intermediate mineral streams, until a steady state is achieved.

On-Site Consulting and Testing

AMML can provide metallurgists for on-site troubleshooting of flotation circuits including plant trials and lab scale tests on plant streams.
