Full Abstract

The ITERAMS ambition is to create a paradigm shift in water resource and tailings management to deliver sustainable mining. ITERAMS uses sulphidic ores as the framework for concept development. The plant is isolated from the surrounding water systems and all water is recycled. Tailings are deposited filter dry.
The closed water circuit results in a complex system, where different process steps and technologies have diverse and interconnected effects on the operations. Complete closure of water loops increases thermodynamic and kinetic instability and process disturbance. Residence time of water storage before re-use is reduced leaving water in a kinetically controlled thermodynamic unbalance. Furthermore, water circulation tends to raise temperature, which could generate bacterial growth. ITERAMS creates capabilities and different tools via laboratory experiments, modelling and validation at mine sites to tackle this complexity.
