Roasting system for sorption waste
The project to improve the technology for extracting gold from refractory ores at the Uchquduq deposit of Navoi Mining & Metallurgical Combinat (NGMK) in Uzbekistan represents a significant investment as part of NGMK’s development program. With the commissioning of the globally unique STR system – a sorption tailings roasting system – we were able to increase raw material efficiency by 8% and production by 11%. In addition, 150 new jobs were created.

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.
Gold extraction plant for complex ores
State-of-the-art bio-oxidation technology for gold in Kokpatas, Uzbekistan: This highly innovative plant, which we developed together with Navoi Mining and Metallurgical Combine, processes 3.2 million tons of complex, sulphide ores annually and sets new standards in the efficiency and sustainability of gold extraction.
