Xiuangguang Copper adopts the core technology of the world’s most advanced flash smelting and flash converting process, which has outstanding features of energy saving, extends reaction shaft life, heightens sulfur utilizing ratio and solidifying ratio, low investment and production cost, high automation and labor productivity, good potential expansion capacity and environment protection performance, and avoiding flue gas pollution and So2 leakage at low altitude. Yanggu Xiangguang Copper is the second copper smelter in the world, which adopts this technology and process.
On building up innovations, Xiangguang Copper utilizes waste heat steam to heat up copper concentrate, high efficient foam washing and purifying and high concentration SO2 conversion technology, recovering precious metal with Kaldo converter process, stainless steel cathode electrolysis, copper electrolyte purification and plate type copper sulphate vacuum evaporation technology, whole process waste heat recycling, and integrated recycling technology for flash smelting furnace. This technology represents top copper smelting technology nowadays in the world. So far as the integrated process and technologies are concerned, Xiangguang Copper is one of the most advanced copper smelter in the world.
   
Copper smelting process flow of Xiangguang Copper: drying cu concentrate - flash smelting – flash converting – Rotary anode furnace refining – permanent stainless steel cathode electrolyzing – reclaiming Kaldo precious metal through converter – off-gas dynamic wave purifying, two conversions and two absorption acid making – middle temperature waste heat recycling process.
   
This process flow has outstanding features of energy saving, environment protection and high efficiency. It combines most advanced copper smelting and acid making technologies to utilize resources and energy maximally, and no influence to environment. Production and energy consumption index and comprehensive resource utilization rate reach leading domestic or advanced international level.
