Hydrometallurgical project of 40,000t/a cathode copper and 7,000t/a metallic cobalt equivalent crude cobaltous hydroxide of LuiLu Resources SAS of Excellen Mining
The project was built in Kolwezi City, Alaba Province, Democratic Republic of the Congo, with raw materials from Luilu tailings and purchased raw oxide ore. The processing capacity is 6000t/d, includi
Comprehensive Utilization Project of GEM Copper-bearing Waste Residue and Sludge
The project mainly processes copper-containing sludge, circuit board pyrolysis slag, copper sulfide slag and other materials, with a processing capacity of 90,000t/a. This project pioneers the use of oxygen-enriched side-blown bath smelting technology instead of the traditional blast furnace process, solving the problems of poor production environment, low automation and inability to deal with dioxins in the flue gas in the traditional process, and realizing harmlessness and recycling of hazardous copper-bearing waste. The project was successfully put into production in 2020. The produces are matte and black copper. The flue gas emission reaches the standard after waste heat recovery, dioxins removal, dust collection, desulfurization, and denitration. The glassy smelting slag (generally solid Waste) is sold as building materials raw materials after water quenching and granulation.
Relocation and Technical Upgrading Project of Chifeng Yuntong 400,000tpa Cu Smelting Operation
Located in Chifeng, Inner Mongolia,the project is based on the process of oxygen side-blown bath smelting-top blown continuous converting, characterized by short process, high equipment operating rate, high heat utilization rate and prominent energy-saving and environmental effect. CINF has undertaken the project as EPC contractor.
