"Development and Application of Key Technologies for Green, Low-Carbon and Short-Process Continuous Copper Smelting"

"The Development and Application of Key Technologies for Green, Low-Carbon and Short-Process Continuous Copper Smelting" was jointly accomplished by Guangxi Nanguo Copper Industry Co., Ltd. and China Nerin Engineering Co., Ltd. for the large-scale industrial application of the "side-blown smelting + multi-lance top-blown converting + anode furnace" three-furnace process and its supporting technologies. The first domestic technology integration demonstration plant for green, low-carbon and short-process continuous copper smelting with an annual output of 300,000 tons of cathode copper and the "side-blown smelting + multi-lance top-blown converting + anode furnace" three-furnace continuous copper smelting as the core technology was built, and stable operation was achieved.

Transformation benefit

The demonstration project carried out with the core technology, the "Phase I 300,000-ton Copper Smelting Project" of Nanguo Copper Industry was completed and put into production in April 2019. As of December 2023, the cumulative new industrial output value has reached 84.995 billion yuan, and the profits and taxes have reached 4.976 billion yuan.

"Research and Development and Application of Two-Way Parallel Flow High Current Density Copper Electrolysis Process and Special Devices"

In 2020, the technological innovation achievement of "Research and Development and Application of Two-Way Parallel Flow High Current Density Copper Electrolysis Process and Special Devices" independently developed by Guangxi Nanguo Copper Industry Co., Ltd. won the first prize of the Science and Technology Award of China Nonferrous Metals Industry.

Transformation benefit

High-purity cathode copper can be stably produced under the condition of current density as high as 350 - 380 A/m². The two-way parallel flow copper electrolysis circulation mode provides superior solution flow field conditions, effectively reduces concentration polarization, and ensures the quality of cathode copper under high current density conditions.
