Core has a long history in the design, commissioning and operation of complex integrated hydrometallurgical pilot plants.
Hydrometallurgical Pilot Plants
Core specialises in pilot plant trials of complex hydrometallurgical processes. Core’s expertise in the design and execution of these pilot and demonstration plants significantly de-risks DFS programmes for our clients. Our senior pilot management staff have backgrounds in commercial due-diligence, in addition to their technical hydrometallurgical backgrounds, ensuring pilot programmes have a strong focus on driving out technical parameters & design criteria that will withstand scrutiny from bankers and other stakeholders.
A Pilot Design Package is prepared ahead of each pilot plant, based on process METSIM models, specifying all physical equipment and software systems, operating procedures, sampling schedules and data management and reporting routines. Core has developed sophisticated dynamic modelling tools to enable evaluation and review of pilot flowsheets ahead of their construction and execution. This modelling is pilot specific, and reflects the subtle differences between a full scale plant and a demonstration or pilot plant.
Core can mobilise any hydrometallurgical pilot plant configuration, and has built and operated demonstration plants up to a 2000 L tank / 5 tpd scale. We specialise in precise control of flows, especially in low-volume low-flow continuous integrated pilot plants.
Core’s knowledge of metal solution chemistry ensures that our process engineers and analytical chemists unlock an understanding of the steady-state chemistry achieved in pilot plants. Our process engineers work hard to identify the effects of impurity build up with recirculation and address their implications during the execution of pilot plants.
Whether your project requires a pilot plant to trial a new process, or a full scale demonstration plant, contact Core today to discuss your project with us.
