At RE TECH, we are committed to helping you achieve your sustainability and resource management goals. Whether you need solutions for lead recycling, copper refining, or comprehensive material recovery, our team of experts is ready to assist you.

The metal recycling and refining industry is fundamental to sustainable development, playing a crucial role in resource conservation, environmental protection, and economic growth. This sector encompasses a broad range of activities aimed at recovering, purifying, and reusing metals from diverse waste streams. By transforming waste materials into valuable resources, the industry helps to reduce the need for mining, lower energy consumption, and decrease greenhouse gas emissions.  Recycling and refining of metals like lead and copper are critical for sustainable resource management. Each step in these processes involves specialized technologies designed to maximize efficiency and minimize environmental impact. As demand for these metals grows, innovation in recycling and refining technologies will play a crucial role in meeting global needs sustainably.

Lead Recycling

Collection and Sorting: Efficient networks are established to collect ULABs and other lead-containing products, ensuring they are properly sorted and not disposed of in landfills.

Breaking and Separation: Batteries are mechanically broken down, and components are separated. Lead is extracted from the battery grids and paste, while plastics and acids are treated for reuse or safe disposal.

Smelting and Refining: Lead components are melted in furnaces to produce lead bullion. Advanced refining techniques, including pyrometallurgical and electrochemical methods, are employed to purify lead to desired quality standards.

Purification and Recasting: The refined lead is cast into ingots or other forms for use in manufacturing new batteries and other lead products.

Technological innovations, such as advanced battery breakers, rotary furnaces, and refining kettles, have enhanced the efficiency and environmental performance of lead recycling processes.

Copper Refining

Scrap Collection and Preprocessing: Copper scrap, from sources such as wires, pipes, and electronic devices, is collected and prepared through shredding and sorting.

Smelting and Conversion: Copper scrap is smelted to remove impurities and produce blister copper, which is about 98-99% pure.

Electrolytic Refining: Blister copper undergoes electrorefining, where it is dissolved in an electrolyte solution and pure copper is deposited onto cathodes, achieving purity levels of 99.99%.

Hydrometallurgical Methods: For lower-grade ores and complex scrap, techniques like leaching and solvent extraction-electrowinning (SX-EW) are used to recover copper in a more environmentally friendly manner.

Key technologies include advanced smelters, electrochemical cells, and integrated SX-EW systems, which enable efficient and high-purity copper production.

Comprehensive Recycling

Material Recovery Facilities (MRFs): These facilities sort, clean, and process mixed recyclables into marketable materials. They employ sophisticated sorting technologies like optical sorters and eddy current separators to efficiently recover valuable metals.

Integrated Recycling Systems: These systems combine mechanical, thermal, and chemical processes to extract metals and other valuable materials from complex waste. Techniques such as pyrolysis and incineration are used to separate metals from non-metallic components.

Urban Mining: Recovering metals from e-waste involves advanced processes including shredding, magnetic separation, and chemical or biological extraction methods to recover precious and rare metals.

Innovative technologies in this area include high-efficiency shredders, automated separation systems, and emerging bioleaching processes that utilize microorganisms to extract metals from ores and waste.
