Everything you need to know about mine water management

The definition of mine water is that it is not a slurry, i.e. generally it is considered to contain <50g/l of solids. Mine water can be categorised into two different streams of water: removal and addition. The first category involves removal of water from the mine area (mine dewatering) and removal of water from the process (process …
