At first glance, sustainability and mineral resource development appear to be in conflict. Mining depletes finite resources and in a strict sense, therefore, is inherently unsustainable. For instance, there is only a finite amount of copper in the earth's crust, and each unit of copper extracted ...
Problems arise when the selected flowsheet is not appropriate for the range of ore properties – a "one size does not fit all" situation. Very often, companies do not appreciate or acknowledge the potential for variations in metallurgical performance, expecting the operations team to make the best of it.
