Jun 21, 2019 In flotation of rare earth ores, in order to simplify flotation process and save flotation reagents, high intensity magnetic separation technology is sometimes used to pre-enrich rare earth ores. Electric separation method: Rare earth ore electroseparation is mainly due to the fact that rare earth ore belongs to non-good conductor.
Iron Ore: Penalty elements in iron ores dilute the overall ore grade and reduce the ore-processing efficiency. Niton analyzers can determine the composition of the iron ore and other base metal deposits (Fe, Cu, Pb, Zn, Ni, Co).

The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's
