铜精矿沸腾层半氧化焙烧在美国田纳西铜业公司炼铜厂获得了成功的应用。以前,该厂的铜精矿直接在反射炉内熔炼成品位21%的冰铜,然后进一步在转炉内吹炼成粗铜。近年来在铜山地区发现一个含铜高的矿体并进行了开采,使铜精矿的处理量增加了30%。为了在不扩大反射炉和转炉能力的条件下来增加冶炼厂的产量,该厂经过试验研究,将铜精矿与石 Copper concentrate boiling layer semi-oxide roasting in the United States tennessee copper smelter won the successful application. Previously, the plant’s copper concentrates were melted directly into refiner furnaces to yield 21% matte, and further blown into blister copper in a converter. In recent years, a copper-bearing ore body was found in the Tongshan area and was mined, which increased the copper concentrate processing capacity by 30%. In order to increase the capacity of the smelter without increasing the capacity of the reverberatory furnace and the converter, the plant has been experimentally studied to combine the copper concentrate with the stone
