Today, Almalyk Mining and Metallurgical Complex – the symbol of large-scale transformation not only in the non-ferrous metals industry but also in the entire national economy – is implementing truly unique and unprecedented projects.

The key strategic areas include the investment project to develop the Yoshlik I deposit, the “AMMC-2030” digitalization program, and major initiatives aimed at modernizing the production processes and enhancing environmental safety.

As part of these transformations, the Complex existing production facilities being consistently brought into compliance with modern technical requirements, and a new production infrastructure is being developed. Of particular significance is the construction of a fully automated sulfuric acid production complex at the Zinc Plant, replacing the outdated one, which was commissioned in 1963. The new facility will not only significantly increase production efficiency but also significantly improve the environmental situation – both at the plant and in Almalyk, ensuring the almost complete capture of gases generated during the process.

Construction and installation works at the site, carried out by the Trust Olmalikmetallurgqurilish, are currently in their final stages. The project was launched in 2024, and since then, a significant amount of works has been completed at key sites: dry electrostatic precipitators, gas cleaning systems, drying and absorption units, contact compressor rooms, cooling and pumping stations, and the main substation.

During the construction, approximately 20,000 cubic meters of earthworks, 13,117 cubic meters of concreting, and 1,251 tons of reinforcement works were completed. Over 750 tons of metal structures and process equipment have been installed, 978 meters of gas ducts over 1,000 mm in diameter have been laid, and 4,184 meters of process pipelines have been installed.

Interior and exterior finishing work continues at the main substation building. Acid pipelines are being laid in the gas cleaning department, and electrical systems are being installed.

Furthermore, the Specialized Repairs Department has completed 98% of the construction and installation works. Specifically, the SRD has installed a 2E400 dry electrostatic precipitator, while an EDITUBE wet electrostatic precipitator has been installed in the first and second gas cleaning departments. Installation of the purge, absorption and drying towers in the drying and absorption departments, as well as converters in the contact compressor departments, has been completed.

Ventilation systems have been installed in the main substation and electrical control rooms. Chemical protection works have also been completed on the equipment. Stainless steel pipelines, SX and PTFE pipelines and gas mains have been fully installed.

It should be noted that back in 2022, the bilateral EPC contract was signed with the German company Metso Outotec, covering the design of the new facility, the supply of process equipment, and construction supervision. Since November 2023, the project has entered the practical implementation phase. The new facility will utilize cutting-edge technologies from FLSmidth (Denmark) and BASF (Germany), fully compliant with international environmental standards.

The used equipment ensures highly efficient filtration of gas emissions, reduced zinc losses, and a significant reduction in the volume of acidic wastewater. As a result, savings of up to 10,000 cubic meters of natural gas and up to 2,000 cubic meters of water per day are expected. Furthermore, modern filtration systems will enable the additional recovery of rare metals.

After commissioning of the complex, it will be possible to produce up to 180,000 tons of sulfuric acid. This, in turn, will increase the overall efficiency of the plant and significantly contribute to further improvements in the town’s environmental situation.
