前言闪速熔炼是二次大战后发展起来的硫化物精矿冶炼新工艺。目前世界上投入生产的闪速炉已超过二十座,其中约80%用于炼铜。经过三十年的发展,闪速熔炼取得很大改进。鼓风制度从单一的中温(400～500℃)鼓风发展成中温、高温(800～1000℃)和富氧三种鼓风制度,实现了反应塔自热熔炼和闪速炉自热熔炼。炉渣处理除电炉贫化外又有了浮选 Foreword Flash smelting is developed after World War II sulfide concentrate smelting new technology. At present, there are more than 20 flash furnaces put into production in the world, of which about 80% are used for copper smelting. After thirty years of development, Flash Smelting has made great improvements. The blast system developed from a single mid-temperature (400-500 ℃) blast to mid-temperature, high-temperature (800-1000 ℃) and oxygen-enriched blast systems. The self-heating reaction of the reaction tower and the self-heating furnace of the flash furnace were realized. In addition to the furnace slag treatment furnace depleted another flotation
