Metal recovery is the process of extracting valuable metals from waste materials, such as scrap metal, electronic waste, or industrial byproducts. This process helps reduce the need for mining new metals, conserving natural resources and minimizing environmental impact. Techniques for metal recovery include physical separation, chemical extraction, and pyrometallurgical methods. Recycling is a key aspect of metal recovery, as it allows for the reuse of metals like aluminum, copper, and gold. By recovering these metals, industries can lower production costs and reduce energy consumption. Overall, metal recovery plays a vital role in promoting sustainability and resource efficiency.
