What factors affect the recovery of lithium minerals?-2

②Lepidolite Al203·3Si02.2(KLi)F, containing Li20 1.2%~5.9%. Coarse lepidolite is enriched by hand selection, winnowing or friction selection, and fine lepidolite is recovered by flotation. Cationic collectors are the best collectors for lepidolite. When octadecylamine is used, lepidolite can be well floated in both acidic and neutral media. Unactivated lepidolite cannot be collected by oleic acid, but after activation with hydrofluoric acid, better indicators can be obtained.

Lepidolite can be inhibited by iron salts, aluminum salts, lead salts, sodium sulfide, starch, and sodium hydrogen phosphate in pulp. Lepidolite can be activated by lithium carbonate and lithium sulfate. A mixture of bleaching powder, sodium sulfide, and starch is the strongest inhibitor when using octadecylamine to sort lepidolite. Lepidolite is inhibited by copper nitrates, aluminum nitrates, and lead sulfates, while it is activated by copper, aluminum, and lead sulfates.
