过去的三十年,硫化铜熔炼、吹炼氧气消耗量的增加,以及计算机过程控制的实现,提高了工艺强度和冶炼厂的精矿处理能力,降低了冶炼的能源消耗,提高了从工艺气流中捕收SO_2的能力。粗炼炉年产100万吨精矿已成为新的工业标准。近年来,顶吹浸没喷枪熔炼技术已成为一种重要的工艺方法。过去的三十年,世界铜冶炼发生了重大调整。受经济快速增长及时基本原材料需求大幅增加的刺激,许多现代大型铜冶炼厂纷纷在中国、印度以及其他亚洲国家建厂,其余地区的熔炼及电解精炼增长缓慢。此外,美国ER铜阴极产量已大幅下降。本文作者讨论了新近的技术进展、行业变化以及一些关注问题,如能源消耗及相应的温室气体排放问题将成为未来讨论的焦点。
Over the past three decades, copper sulphide smelting, increased oxygen consumption during blowing, and computer process control have resulted in increased process strength and smelter’s concentrate processing capacity, reduced energy consumption for smelting, improved process flow from process streams In the capture of SO_2 capacity. Smelting furnace with an annual output of 1 million tons of concentrate has become the new industry standard. In recent years, top-blown immersion gun melting technology has become an important process. Over the past three decades, the world’s copper smelting has undergone major adjustments. Stimulated by the rapid economic growth and the substantial increase in demand for basic raw materials in a timely manner, many modern large-scale copper smelters have set up factories in China, India and other Asian countries in succession, and the smelting and electrolytic refining in other regions have been slow to grow. In addition, the United States ER copper cathode production has dropped significantly. The authors discuss recent technological advances, industry changes, and concerns such as energy consumption and corresponding greenhouse gas emissions issues that will be the focus of future discussions.
