Core has sample preparation facilities capable of processing samples from a few kilograms up to several tonnes. Batch and continuous milling equipment is available for processing up to 500 kg of sample per hour for pilot plant operations.
Pilot Scale Crushing
Core’s sample preparation facilities are capable of handling several tonnes of rock or sand material. We have a wide range of equipment that can be used for a variety of sample preparation and crushing applications. Fast turnaround of large jobs can be provided for projects on a short timeline.
Pilot Scale Milling
A 10 kW pilot scale ball mill and a 200 L rod mill at Core can be operated in closed or open circuit configurations. Core is equipped with a conveyor belt and 2.5 T hopper and vibratory feeder system and other equipment necessary for even larger pilot milling or sample preparation operations.
A range of fine and ultrafine grinding equipment is available for milling of sulphide concentrates, including M1 & M4 IsaMills™.
Selected comminution/milling pilot plant examples:
Reduce 4 tonnes of Nickel Laterite sample to -75 µm, on a very short time frame (<2 weeks). Work included gamma sterilisation of samples (for quarantine), drying of samples, hammer milling, splitting, rod milling, oven drying, and further rod milling.
Prepare 1,800 kg of Iron Ore for a magnetic separation project.
Prepare 5,200 kg of refractory gold drill core for a flotation/leaching project.
Many other sample preparation programmes reducing drill core to sub 100 µm for other flotation and hydrometallurgical programmes.
