Electromagnetic separation is a technique used to separate materials based on their magnetic properties. It involves using a magnetic field to attract and isolate magnetic materials from non-magnetic ones. This method is commonly applied in industries like mining and recycling to efficiently separate valuable metals from ores or waste. The process typically involves passing a mixture through a magnetic separator, which generates a magnetic field. As the materials move through this field, magnetic particles are pulled towards the separator, while non-magnetic materials continue to flow away. This technology is essential for improving resource recovery and reducing waste in various applications.
