Many processes are not fully optimised. Variability of the ore characteristics, increases in throughput or general wear and tear over time, for example, are often overlooked. Material properties may no longer be the same as the first bulk sample collected during pre-feasibility. Process performance affects recoveries and water conservation impacts operating costs. For these reasons, Paterson & Cooke has a dedicated group focusing on providing follow-up field services to our clients.

This team provides the opportunity to apply our engineering and field experience in a way that optimises and upgrades the infrastructure already in place. We provide a range of field services including on-site pilot scale test work, design reviews, equipment and process audits, performance optimisation, upgrades & retrofits, performance validation, benchmarking, start-up, commissioning and operator training. The strength of our team comes from years of field experience and access to Paterson & Cooke’s global resources which enable us to tackle unique process challenges.
