    2013-5-1 · 1. Introduction. Fluorite flotation is usually realized with sodium lignosulfonate as depressant and fatty acid as collector at a high pH (Crozier, 1992, Ayhan et al., 2006).In the case where feed ores contain a significant amount of fine particles, the sedimentation rate of fine particles was found to be significantly slow due to the effective dispersion of the fine particles

    2021-4-1 · The beneficiations of fluorite ores from different gangue minerals are summarized in Table 4. Oleic acid is the most significant collector, and it can render the fluorite hydrophobicity when the slurry pH range is at 8–11. Additionally, it is worth noting that the water used in fluorite flotation should be softened when adopting oleic acid.
