13.5.2 High-Intensity Magnetic Separators. Weakly paramagnetic minerals can only be effectively recovered using high-intensity (B-fields of 2 T or greater) magnetic separators (Svoboda, 1994). Until the 1960s, high-intensity separation was confined solely to dry ore, having been used commercially since about 1908.
