Eddy Current Separation
Eddy Current Separation is a method used in recycling and waste management to sort different types of materials, particularly for separating non-magnetic metals (like aluminum cans) from other waste. Think of it like a special conveyor belt system that automatically pushes aluminum away from other materials using magnetic fields. This technology is important in modern recycling facilities because it makes the sorting process much faster and more accurate than manual sorting. Similar technologies include magnetic separation and optical sorting. When you see this term in resumes, it usually means the person has experience working with automated recycling equipment.
