Реферат | The results of theoretical and experimental studies on application of aerofloats are analyzed, revealing their highly selective action in separation of base metals sulfides from iron sulfides. The mechanism of reagents interaction with minerals is shown, consisting in formation of coordination compounds through transition of undivided pairs of electrons of sulfur to unoccupied orbitals of metals in mineral lattice. A high efficiency of fine mineral particles flocculation with application of aerofloats with chain length С4–С12, synthesized by the authors, if compared with butyl aerofloat, is shown. The conducted studies permitted to synthesize aerofloats of BTF series, featuring different collecting properties. The results of laboratory and commercial-scale testing of BTF152, BTF1522, BTF1541, BTF1711 aerofloats are presented, verifying, that in comparison with butyl xanthate they provide for a considerable increase in copper recovery (by 2.2–5.1 %) from copper and coppernick el ores, as well as total gold and silver (by 3.2–14 %) from different types of silver and goldcontaining ores. |
