THIS invention relates to a method of disposing of residues from the comminution and
processing of ores. The method includes the steps of classifying the processing residues into a water permeable sand fraction and a tailings fraclion and depositing the tailings fraction and the sand
fraction to form a multilayer structure contained by al least one containment wall
(14) with the sand fraction forming conlinuous channels ('12) through the tailings
fraction (10) to allow water contained in the tailings and sand to flow by
gravity, through the sand channels, to water discharge points (16),
and recovering the water (18) from the water discharge poinls.
