guide questions: :1. what products were made using,magnetic separation is also useful in mining iron as it is attracted to a magnet. explanation: recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the recycling industry..eriez magnetic separation,electromagnetic separators use wire coils and direct current to provide a magnetic field which can be used to separate ferrous material from non ferrous products. electromagnetic separators offer greater flexibility and strength as well as different magnetic fields for specific applications..selective flocculation enhanced magnetic separation of,simple magnetic separation for a certain magnetite mine with ultrafine disseminated lean ores has resulted in low performance, as the fine sizes and aggregation of ground mineral particles have caused inefficient recovery of the ultrafine minerals. in this study, we attempt to increase the apparent sizes of target mineral particles, and improve the separation indices, by using a multi-stage.magnetic separation using superconducting magnets,rotating-drum magnetic separators are mainly used in mines. a good example of this technology is a magnetic separator operated in one of the largest anatase tio 2 mines in the world, located in tapira, minas gerais, brazil, used to remove ferromagnetic impurities in the ore. other magnetic separators are used to enrich ti after heat treatment..
