What is the future direction for the copper smelting industry?
Thread Content
Most domestic copper companies still import minerals from abroad. The world’s copper reserves are not abundant either; so what new technologies should the copper industry develop, what new directions should it take?
Yeah, what’s the general trend? Many places are currently implementing large-scale copper smelting projects, and most of them rely on imported copper ore. In that case, isn’t it as if they’re voluntarily placing their own fate in the hands of others?
In fact, the recycling of copper waste has been going on for several years now; it’s just that the development of the industry related to the reuse of metal resources is slow, and there is a lack of effective policy guidance. If proper management could be implemented for the recycling of waste metals, the crisis resulting from shortages of metal resources could be alleviated. Japan attaches great importance to the recycling of metal resources; it possesses advanced technology in this field as well as a complete industrial chain. I believe that focusing on the development of the industry and technologies related to the recycling of scrap metal resources is a crucial element for achieving sustainable development in the metallurgy sector.
Pay attention to the smelting technologies for low-grade copper ores, develop hydrometallurgical copper processing techniques suitable for such ores, and promote the use of these technologies for processing low-grade copper ores.
Energy-saving approach: The pyrometallurgical process can be combined with waste heat power generation, with the electricity generated being used internally or supplied externally, thereby reducing energy consumption, cutting costs, and pursuing a path of energy-efficient smelting.
I’m not sure how much development there is in the recycling and processing of copper waste
The future development directions are to save energy and reduce pollution. Flash smelting and flash blowing are areas worthy of research; since the mechanism of flash blowing differs greatly from that of converter blowing, there is still much to be studied in this field
