Process Plant Design, Test work and Flowsheet Development Studies

To maximize a mining project’s economic returns, it is essential to analyse the mineral’s metallurgical characteristics and the available processing options. This should be done at all project stages, from exploration and evaluation through to plant operation, and when planning circuit changes and expansions.

GPG’s experienced metallurgists and processing engineers will help you develop and evaluate metallurgical test work programs, design flow sheets, optimize operations, and conduct technical studies and due diligence audits. We will also act as technical advisors to support and mentor your operations personnel.
