Abstract: Lead, stibium, zinc and cassiterite were recovered from slime system of Chehe plant. To avoid the harmful effact of lime on the subsequent recovery of cassiterite, the preferential flotation flowsheet was adopted under the natural pH, in which lead was floated firstly and then zinc and sulfur was floated and seperated. A recovery of 72.88% into a concentrate assaying 24.38% Pb together with 22.07% Sb, and a recovery of 83.47% into a concentrate with grade of zinc 47.52% Zn could be achived.
