Metal separation is a process that involves separating different types of metals from a mixture based on their unique physical and chemical properties. This can be achieved through various techniques such as magnetic separation, flotation, gravity separation, and leaching. Metal separation is crucial in industries such as mining, recycling, and waste management, where the recovery and recycling of metals are important for economic and environmental reasons. Researchers in this field work to develop innovative and efficient methods for separating metals to improve the overall efficiency and sustainability of metal extraction and recycling processes.
