Green Equipment & Technological Innovation

Green Equipment & Technological Innovation

Committed to advancing green equipment and technology, we enhance energy efficiency and promote environmentally friendly aluminium production. Plans are underway to further reduce energy consumption and extend equipment lifespan through optimised average voltage, improved cell design, and enhanced cell lining materials.

  • Electrolytic Cell

    A comprehensive aluminium smelting system is in place, ensuring a seamless power supply cycle from input to output, facilitating aluminium production. Key production units include electrolytic cells, power supply systems, holding furnaces, and casting machines. Each is designed with cutting-edge technology and proven processes, with a strong focus on energy conservation, emission reduction, and efficiency upgrades. Continuous process optimisation enhances product competitiveness and meets the demands of high-end downstream processing.

    Ongoing advancements in electrolytic aluminium production aim to lower electricity consumption per ton of aluminium. Multiple technical upgrade projects have been planned and implemented, with completion expected by the end of 2025.

  • Precipitator

    We employ advanced limestone-gypsum technology for desulphurisation, defluorination, and dust removal. Dust emissions remain below 1.5 mg/m³, significantly lower than the national standard limits for electrolytic aluminium.

  • Desulphurisation System

    Innovative wet flue gas desulphurisation technology has been developed to simultaneously remove sulphur and fluorides. The limestone-gypsum wet desulphurisation method ensures sulphur dioxide emissions remain below 27 mg/m³.

  • Equipment Upgrades

    Our electrolytic aluminium production per capita far exceeds industry averages. While China's electrolytic aluminium per capita annual production ranges between 260–280 tons, historical records show our output reaches 590–670 tons, 2.2 to 2.6 times the industry average.

Industry-Academia Research Collaboration

Actively partnering with leading universities and research institutions, we integrate academic research, technological exploration, and industry expertise to foster an open and innovative ecosystem for collaborative growth. Holding 129 patents, including 125 utility model patents and four invention patents, we continuously drive advancements in the aluminium industry.

Ultra-Low Emission Project

Ultra-Low Emission Project

First Prize in the National Nonferrous Metal Technology Standard Excellence Award

The electrolytic aluminium smelting process generates large volumes of emissions. While the pollutant concentration is relatively low, existing technologies struggle to further mitigate environmental impact. To address this, we have developed wet flue gas desulphurisation technology, which effectively removes both sulphur and gaseous fluorides from emissions. Additionally, we have introduced advanced particle capture technology, utilising cooling, phase transformation, aggregation, and recapture processes to trap fine particulate matter.

This breakthrough has earned the First Prize in the National Nonferrous Metal Technology Standard Excellence Award and has been successfully demonstrated in the aluminium smelting sector. It exemplifies our commitment to green production and our ability to deliver economically viable, near-zero-emission solutions for the sustainable development of China’s aluminium industry.

Valuable Recovery and Resource Utilisation of Red Mud

Valuable Recovery and Resource Utilisation of Red Mud

In 2023, we partnered with a university to develop an integrated red mud recycling system. This system optimises alkali extraction, achieving an alkali recovery rate of over 90% and an alumina extraction rate exceeding 50%. The processed red mud is rendered virtually alkali-free, making it suitable for soil remediation, iron extraction, and construction material production, significantly expanding its potential applications.
