Currently, gangue utilization mainly focuses on brick production and low-quality coal recovery. However, these solutions have limited applications and low economic value, making it difficult to achieve full resource utilization. As regulations on gangue disposal become increasingly stringent, underground backfilling is gaining wider adoption. Direct backfilling, however, wastes potential high-value products and accelerates equipment wear due to hard minerals, resulting in high backfilling costs.

To address these challenges, Meiteng Technology promotes a comprehensive gangue utilization approach based on “high added value” and “complete consumption.” Three typical solutions include:

-Low-quality coal sorting + brick production

-Low-quality coal / kaolin / construction aggregate sorting + underground backfilling

-Coal gangue soil production + sand control and ecological restoration

These processes not only recover high-value products and enable “coal gangue soil production + sand control and ecological restoration,” but also achieve the systematic and integrated utilization of gangue, enabling its complete consumption.

Our metal sorting and recycling solutions are designed to tackle the challenges of inefficient or ineffective classification of various scrap metals in the recycling process. With the growing global focus on the “urban mining” concept, metal recycling has become increasingly important. Recycling metals not only reduces waste but also shortens production cycles, saves energy, and helps minimumize the environmental impact of traditional mining.

Leveraging nearly a decade of expertise in optical sorting technology, MeiTeng Technology achieves high-efficiency, precise classification and recovery of a wide range of scrap metals. Our solutions support the global strategy for sustainable metal resource utilization, contributing advanced technology and innovative approaches to the circular economy.

Meiteng Technology focuses on physical separation methods, leveraging its expertise in the pre-sorting stage of lithium battery recycling. By precisely dismantling retired cells, our process achieves high-purity recovery of both cathode and anode powders.

The separation and processing of cathode and anode materials not only enables the physical restoration of lithium iron phosphate batteries but also enhances the efficiency of hydrometallurgical recycling processes, significantly reducing production costs. Unlike traditional acid-base treatments, MeiTeng’s battery recycling approach is environmentally friendly, aligning with global green development initiatives. This method minimizes environmental impact while supporting sustainable recycling practices, demonstrating MeiTeng Technology’s commitment to environmental responsibility and adherence to international policy standards.
