Abstract: An apparatus for powering trucks including a power module skid and supporting structure for fitting on a truck. The skid housing hydrogen fuel cell modules, battery sub packs, cooling means and cooling management, and integrated power electronics, to provide an electrical drive train of the truck with a constant high voltage DC power supply. An integrated system using renewable energy to reduce greenhouse gases using one or more trucks, in which an integrated system includes: means for providing renewable energy; means for using the renewable energy to synthesise hydrogen; means for storing the synthesised hydrogen. The integrated system includes hybrid hydrogen power modules fitted to each truck including hydrogen fuel cell modules and battery sub packs so that the battery sub packs and the battery sub packs are recharged by the hydrogen fuel cells.

Abstract: 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.
