method for the recovery of oxidized lead and zinc minerals from ores at present is flota-tion (Onal G. et al., 2005). The flotation of oxidized lead and zinc minerals, particularly zinc minerals, is much more difficult than the flotation of corresponding sulfide miner-als. Hexyl and amyl xanthates are capable of collecting smithsonite.
