Copper smelter and lead works
As part of a comprehensive project from 2006 to 2011, we – with Glencore International AG as the main investor – built a copper smelter with electrolysis for Kazzinc Ltd. and modernized and expanded the lead plant. The aim was to increase production capacity, improve efficiency and significantly reduce the environmental impact through innovative technologies.
Commissioning of copper smelter: 2011, lead works: 2012

Customer benefits
Successful start to copper production: the new copper smelter meets the high efficiency and capacity requirements
Increased productivity in lead production: the modernization of the lead plant led to a significant improvement in production quality and quantity
Compliance with strict emission targets: The modernization has significantly reduced the emission of harmful substances compared to the old plant
Environmentally friendly processes: The exhaust gases from the lead plant are recycled in the production of sulphuric acid, which significantly reduces air pollution
Reduction of the
environmental impact
environmental impact
With our expertise in the modernization and new construction of complex industrial plants, we have developed a forward-looking solution for Kazzinc Ltd. that not only increases efficiency but also reduces environmental impact.
Success stories that count.
Flue gas desulphurization system
State-of-the-art environmental technology for sustainable energy: our flue gas desulphurization plant at the Šoštanj power plant ensures a significant reduction in sulphur emissions and meets the highest environmental standards.
Phosphate treatment plant & calcination plant
Efficient phosphate ore processing in Uzbekistan: Following the successful commissioning of the phosphate processing plant at the "Tashkura I" deposit, we increased production capacity by 52 t/h with the construction of the calcination plant at the "Tashkura II" deposit and set new standards in the use of resources and technological development.
Copper smelter & lead works
Modernized copper and lead production in Kazakhstan: We have built a copper smelter with electrolysis and an expanded lead plant for Kazzinc Ltd. to increase production capacity to 87,500 tonnes of copper and 100,000 tonnes of lead per year and improve the environmental footprint through innovative technologies.
Thickening plant
Sustainable innovation for iron ore in Ukraine: With a state-of-the-art thickening plant, we are improving processing capacity for UGOK and significantly reducing the environmental impact through efficient process water treatment and waste minimization.
Copper smelter / Vanyukov furnace
Efficient copper production in Almalyk: With the innovative Vanjukov furnace, we enable an annual production of 73,800 tons of blister copper for JSC Almalyk MMC and improve both the production output and the environmental balance thanks to modern slag bath technology.
Roasting plant
Globally unique STR system for gold extraction in Uchquduq: With the innovative roasting plant, we are increasing raw material efficiency for NGMK by 8% and setting new standards in the processing of refractory ores with a capacity of up to 83 tons/hour.
