Abstract

See full text

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 fraction and depositing the tailings fraction and the sand fraction to form a multilayer structure contained by at least one containment wall (14) with the sand fraction forming continuous 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 points.
