Biography of Main Speaker.
Mark Coghill has 40 years experience in mineral processing, tailings and water management. His interest in clay solid-liquid separation led to a career leading and influencing tailings projects and operational studies across all Rio Tinto commodity groups.These projects include process design and optimisation, tailings reclamation, slurry transport, evaporation suppression, new technology research and site closure strategy development.

Rio Tinto is a leading global mining and metals company with operating sites and projects in thirty-six countries. Process flowsheets are typically developed and modified using geometallurgical models which tend to focus on the ore body and process recovery of the valuable minerals.  As world ore grades decline, and the ore mineralogy becomes more complex, this approach needs to be expanded to include a mineral waste management perspective. Mark Coghill will discuss this mineral waste perspective and the need to understand the mineral waste rheology to maximise the project value, minimise the threats and develop new commercial opportunities.
