Ausmelt top submerged lance technology is at the cutting edge of technological developments in non-ferrous metal smelting with commercial operations throughout the world. The Technology is being used for lead smelting, copper smelting and matte converting, fuming zinc from slags, recycling iron residue from zinc plants, processing the aluminium industry hazardous waste SPL , precious metal processing, nickel-copper residue smelting and converting, and tin smelting. The Technology is also being developed for projects involving iron-making and waste industry opportunities. There are 19 furnaces operable or under design at the time of writing. The benefits to operators using Ausmelt Technology vary depending on application, but typically result from environmental improvements, enhanced recovery of valuable products, lower capital and operating costs, more flexible operations capable of handling a wide range of feed materials, better removal of impurities, or improved product quality. Growing industry acceptance of the Technology is evidenced by the fact that more than 20 per cent of the world's tin production will be extracted in systems using Ausmelt Technology when the Yunnan Tin Corporation plant starts up in 2001. Metallurgists, industrialists and investors have accepted the Technology for improved operations in both greenfield main smelters and add-on plants in Korea, China, Japan, Germany, Peru, Zimbabwe, India, Namibia and Australia. Ausmelt intends that this paper will update the industry by outlining recent achievements of the Technology in global metallurgical operations.
