Magnetic separation in mineral processing
Magnetic separation (mag sep) is a process that separates solids/solids mixtures using a magnet, which extracts the magnetic components from the non-magnetic ones. It is most often used in mining and mineral processing applications, although it is also used in recycling applications to separate plastic from metals.
Processing the ores of rare-earth elements | MRS Bulletin
Current mining and processing operations tend to have low recoveries, on the order of 50–80%, from ore to high-purity REE compounds. 5 Inefficient recovery is partly due to the low intrinsic value of the geologic resource compared with the processing costs. The processes for REE ores have been characterized by occasional major developments …

Magnet Manufacturing Process | How Are Magnets Made
Magnet Manufacturing Process. There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via "liquid phase sintering". Therefore, these magnets are most often called sintered magnets.
