Boddington Bauxite Mine in Western Australia is officially recognised as having the world's longest and second-longest single belts with a 31-kilometre-long (19 mi) belt feeding a 20 km (12.5 miles) long belt. This system feeds bauxite through the difficult terrain of the Darling Ranges to the Worsley Alumina refinery. The longest single-belt international conveyor runs from Meghalaya in India to a cement factory at Chhatak Bangladesh.[12][13][14] It is about 17 km long and conveys limestone and shale at 960 tons/hour, from the quarry in India to the cement factory (7 km long in India and 10 km long in Bangladesh).
