摘要
The invention relates to a process for separating accompanying minerals which are weakly magnetic from useful minerals or ores which are nonmagnetic or less magnetic than the accompanying minerals that are to be separated therefrom, and it is its objective to make magnetic pre-separation of such weakly magnetic accompanying minerals feasible. This is achieved in accordance with the invention in that the ore is crushed to a grain size of 0.2 mm at most, and is separated in a magnetic separator operating with a strong magnetic field, if desired after removal of the strongly magnetic fragments of grinding bodies by means of a magnetic separator operating with a weak magnetic field, and prior to separation by flotation, which may also be applied if desired.
