A 300kt/a Copper Smelting Project of Nanguo Copper (Phase I) Designed by China Nerin has been Successfully Put into Production at its First Testrun
At 3:13 a.m., April 14, the 300 kt/a Copper Smelting Project of Nanguo Copper (Phase I) designed by China Nerin Engineering Co., Ltd. produced its first qualified anode plate, marking China Nerin has successfully applied another leading new copper smelting technology. The “side-blown smelting + multiple-lance top-blown converting” continuous copper smelting system with the largest design capacity in the world as a single production line has been successfully put into production.
Nanguo Copper (Phase I) was designed to produce 300 kt/a cathode copper and 1,200 kt/a sulfuric acid with the “side-blown smelting + multiple-burner top-blown converting” continuous copper smelting process. The blister copper produced from copper concentrate is sent to a rotary anode furnace. Afterwards, the anode plates are sent to a tankhouse with permanent stainless cathode plates. The smelting gas is recycled to produce sulfuric acid with non-equilibrium high-concentration SO2 conversion technology. The smooth completion and testrun of the project proves that the process of “side-blown smelting furnace + top-blown converting furnace” is capable of producing high-quality blister copper with high copper and low sulfur contents and breaks through the barrier of other continuous copper smelting technologies, i.e. high sulfur in blister copper. China Nerin also supplies dedicated equipment such as interlocking copper electrolytic unit, waste acid sulfurization for heavy metal removal and comprehensive utilization plant for the project.
The project is located in the China-ASEAN Youth Industrial Park in Fusui County, Chongzuo City, Guangxi. It is planned to produce 1,000 kt/a cathode copper and the project will be constructed in three phases. Currently, Phase II is under engineering design and the preliminary work of Phase III has also started. China Nerin will provide the best technologies and the best services to build Nanguo Copper a beautiful modern smelter with advanced technological level and powerful market competitiveness at home and abroad. With such a high starting point, Nanguo Copper will make leapfrog developments towards a green, large, intelligent smelter.
The copper smelting project of Nanguo Copper is invested by Guangxi Nanfang Nonferrous Metal Group Co., Ltd. The waste water will be 100% recycled and the project will reach or be superior to the domestic advanced level in terms of technical equipment, comprehensive energy consumption and environmental protection and energy saving. The capital and operation expense per ton of copper in the project are both of obvious advantage. The construction of Nanguo Copper will exert profound influence on optimizing China's copper industry chain layout and advancing the global copper smelting technologies.
