Aral recommends companies take a scientific approach – knowing the volume and composition of the process and amount of fresh water running in every unit operation in the plant provides a mine with the knowledge to be able to minimise the use of fresh water. The scientific approach involves computer modelling and optimisation of the flows plant-wide.
