SGS has a proven solution for grinding circuit design, optimization and production forecasting during development or operations.
In the early stages of a project, bench scale tests are used to characterize ore samples.
For subsequent design simulations, the Comminution Economic Evaluation Tool (CEET®) and JK SimMet are used.
At the bankable feasibility stage, or for production forecasting, a more rigorous model of the orebody is created using the geometallurgical methodology pioneered by SGS. Design uncertainty is quantified using statistical techniques.
Due to size, complexity, or desire for absolute minimum start-up time or maximum operational efficiency, there is no substitute for pilot testing. The best pilot programs are supported by thorough, bench-scale orebody characterization and circuit simulation.
SGS provides a comprehensive range of test work services for the coal and iron ore industries. Our extensive global network of laboratory and metallurgical testing facilities support most of the processes that are used in the exploration and treatment of iron ore and coal globally. All physical separation techniques can be tested at SGS, both on the laboratory and pilot plant scales. We have expertise with beneficiation techniques including:
SGS mineral processors have operated many SAG plants and have conducted over 500 SAG pilot plants. We have designed the largest installation base of advanced control (expert systems) for comminution circuits in the world. Our reference list speaks to our global experience and includes grinding circuits, both large and small, including the largest operating grinding circuit in the world – Collahuasi Rosario’s 40-foot SAG mill.
SGS’s philosophy is to understand the variability in your ore and then design, optimize, or forecast from this knowledge. We bring proven technology from the geological and processing disciplines, relying on not just one methodology but several, to provide a bankable solution that is unmatched in its rigor.
