Two laboratory-scale facilities for dry magnetic separation using superconducting magnet systems are described. The results of magnetic separation of pulverized coal samples from various open-cast mines in Czechoslovakia, using these facilities, are presented. The efficiency of both open-gradient and high-gradient magnetic separation techniques, together with pretreatment of coal samples, are discussed.
