(588809)APPLICATION AND DEVELOPMENT OF MODERN COPPER METALLURGICAL TECHNOLOGIES IN CHINA'S COPPER INDUSTRY

摘要

In the last decade, the copper industry in China has developed rapidly and attracted the world's attention. The production capacity of refined copper has grown remarkably from 4.578 million tons in 2010 up to 9.029 million tons in 2018, accounting for about 40% of the global refined copper production. And now, China has become the biggest refined copper producer in the world. This paper summarizes the application of modern copper metallurgical technologies such as Outotec flash smelting/converting technology, Cyclone smelting technology, TSL (ISA/Ausmelt) smelting/converting technology, Jinfeng side blown smelting and Baiyin side blown smelting technology, Chifeng side blown smelting and continuous top blown converting technology, SKS bottom blowing technology, Dongying two-step smelting technology, copper electrorefining with high current density, etc. in China's copper industry, analyzes and compares the characteristics of those technologies and presents the great efforts of China's copper smelters in adapting to the increasingly strict emission standards and improving economic benefits of copper smelters.
