The Role of the Metallurgist in Project Development

The role of a project metallurgist is diverse and covers input into the resource definition, mining studies, metallurgical test program development, process engineering and plant design, cost estimate preparation and financial analysis aspects of project feasibility studies. Mining project schedule and cost overruns can often be attributed to cutting short metallurgical test work, engineering and cost estimating leading up to commitment to development. In a significant number of cases this may result from the lack of understanding and commitment by the project proponent to the requisite metallurgical and processing studies required during the various pre-commitment stages of a mining project. Metallurgical test work, process development, engineering and cost estimating requirements for each stage of pre-commitment development are described together with a summary of the ongoing role of the project metallurgist during detailed engineering and commissioning of a process plant.
