Both hand selection and gravity beneficiation can obtain coarse-grained metallurgical grade fluorite lump ore. However, the manual selection method has low efficiency and high labor costs, so it is only used for the pre-selection of large fluorite ores, and small pieces and granular fluorspar ores still need to be sorted by re-selection.
