Ensuring Mine Water Management
The definition of mine water is that it is not a slurry, i.e. generally it is considered to contain <50g/1 of solids. Mine water can be categorised in two different streams. The first is removal of water from the mine area (mine dewatering) and removal of water from the process (process dewatering). Mine water originates from several sources.
