Abstract
This paper describes the development and testing of a drum medium—intensity permanent magnetic separator. The magnetic field strength on the drum surface can be increased to 0.8 T using a new magnet technology. Uniform distribution of a feed can be achieved with a two—stage feed system. Industrial tests were carried out using a manganese mineral from DouLan manganese mine. The results obtained show that good separation results can be obtained using the separator, with upper limit of the separation size being 30 mm.
