艾萨熔炼法——不只是昙花一现

ISASMELT——Not just a flash in the pan

艾萨炼铜法(CopperISASMELT)于20世纪90年代出现在世界金属产业中,现在,它每年要处理掉300万t精矿和再生铜物料。在澳大利亚、美国、比利时、印度、德国和中国的一些冶炼厂用浸没喷枪熔炼技术生产铜冰铜或金属铜。芒特·艾萨矿业公司的艾萨炼铜炉每年处理超过100万t的含铜物料。炉龄通常超过2年。本文介绍位于芒特·艾萨的艾萨炼铜炉的现状,并将它的性能与新近在中国和印度建造的2座炉子做一比较。文章还概括介绍了连续吹炼工艺的发展,该工艺将使用与艾萨熔炼法相似的工艺原理,它很可能会取代PS转炉。

The Copper ISASMELT process, a technology that emerged into the global metals industry during the 1990s, is now processing more than three million tonnes of concentrates and secondary copper materials each year. The submerged lance smelting technology produces either copper matte or copper metal in plants located in Australia, the United States of America, Belgium, India, Germany and China. The Copper ISASMELT furnace at Mount Isa Mines is treating more than one million tonnes of copper-bearing feed per year. Furnace campaigns of more than two years are now standard. This paper describes the current status of the Copper ISASMELT furnace at Mount Isa and compares its performance with that of the two most recent installations in China and India. It includes a summary on development of a continuous converting process. This process will employ similar process fundamentals to ISASMELT and has the potential to replace Peirce smith converters.
