Sažetak
Demand for metals continuously increases so that metal collection and recycling of waste containing metal become very profitable. Firstly, it refers to steel, copper, aluminium, lead, zinc and their alloys. These metals can be collected selectively (aluminium and steel tins), collected as refuse products (old cars, household appliances, electronic waste) or mixed with other materials (municipal waste). Selectively collected metal does not contain other material impurities and it is compacted (baled) and sold as a metal. Waste which contains other materials besides metal has to be recycled. The recycling process usually includes comminution, classification and separation. Crushers and mills are used for comminution, screens for classification and magnetic separators for metal separation. There are two main types of a magnetic separators: separators with slow rotation speed (drum and belt separators) and separators with high rotation speed (eddy-current separators). The former are used for the separation of magnetic materials (steel, iron) and the latter for the separation of nonmagnetic materials (aluminium, copper, lead, etc.). The paper describes the working principle, application and efficiency of magnetic separators in the recycling of various waste.
