Reducing mine water requirements
Installing the combined system thus reduces the water lost from 38,955 m 3 /d to 10,878 m 3 /d, a savings of 28,077 m 3 /d. This allows the raw water requirements to be reduced from 37,935 m 3 /d to 9858 m 3 /d, a savings of 74.0%. Fig. 5 shows the savings achieved in the different water sinks at the mine.
