  • Flotation Behavior Of Iranian Oxidized Zinc Ore Using

    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 difficult than the flotation of corresponding sulfide miner-als. Hexyl and amyl xanthates are capable of collecting smithsonite.The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.

  • Flotation Of The Oxidized Ores Of Zinc By Fred Henry Bunge

    Jul 05, 2019 The reason why oxidized lead and zinc ores are difficult to separate than sulphide lead and zinc ore is the complex component, unstable associated components, fine fineness, similar flotation characteristic, mud and soluble salt in it. Among the oxidized lead and zinc ores, there are white lead ore (PbCO3), lead alum (PbSO4), zinc turpentine.Flotation recoveries of oxidized copper minerals and oxidized lead ores. (Orwe, Grano, and Lauder, 1998 Kongolo et al., 2003 Castro, Goldfarb, and Laskowski, 1974). Studies by Lee et al.

  • Some Beneficiation Technology Of Oxide Lead Zinc Ore

    Apr 01, 2015 However, flotation of oxidized lead and zinc, in particular zinc minerals, is much difficult than the flotation of corresponding sulphide minerals [1]. Oxidized zinc ores have long been an important source of zinc which can be floated with long chain primary amines as collector after sulphidizing with sodium sulphide [2].However, methods for treating the oxidized ores of cop per and of lead have been devised, and have been tried on a working scale. The most prom ising of these are based upon the sulphidizing, or coating of the oxides with a film of arti ficial sulphide, so as to present a surface suit able for flotation.

  • Flotation Of Zinc Oxide Ore Using Cationic And Cationic

    We have found that oxidized zinc ores in general, and the oxidized zinc-bearing tailing resulting from flotation concentration of the lead present in mixed lead-zinc oxidized ores in particular, may be concentrated by flotation in the presence of a soluble sulphide and a soluble compound of an aliphatic amine containing from 8 to 18 carbon atoms.The two commercially important oxidized zinc minerals under consideration are smithsonite, the zinc carbonate and hemimorphite, frequently referred to as calamine, the silicate of zinc. Deposits of the oxide minerals are numerous but unless the ore is selectively mined or amenable to concentration by hand picking or gravity methods, it has not.
