Abstract:
    The present invention provides flocculating carrier flotation technology for superfine lean Pb-Sb-Zn ore, and features that the superfine lean Pb-Sb-Zn mineral from ore tailing and ore slime are recovered and utilized in two systems. The ore tailing is recovered through depurating flotation, agglomerating flotation, once crude dressing, once fine dressing, once scavenging and returning middling to obtain rough zinc concentrate. The ore slime is recovered through flocculating deposition, agglomerating flotation, once crude dressing, twice fine dressing, once scavenging and returning middling to obtain lead-antimony concentrate and lead-antimony tailing. The lead-antimony tailing and the rough zinc concentrate are merged, dispersant is added into the mixture, and the mixture is recovered through dispersing floatation, once crude dressing, thrice fine dressing, twice scavenging and returning middling to obtain qualified zinc concentrate while discarding final tailing.
