  • Depression Of Pyrite In The Flotation Of High Pyrite Low

    Pyrite is one of the major diluents of copper lead and zinc concentrates One explanation for the high flotation of pyrite in alkaline pH conditions is its inadvertent activation by copper either dissolved from copper minerals present in the ore or added in the zinc circuit to activate the flotation of sphalerite Bushell and Krauss 1962.Apr 01 2015 In the present study the flotation behavior of oxidized zinc ore from Angooran deposit Iran was studied using several cationic anionic and mixed (cationic anionic) collectors by means of bench scale flotation studies 2 Materials and Methods The oxidized zinc ore samples were obtained from Angooran deposit Iran.

  • 1 Froth Flotation – Fundamental Principles

    In many types of ore pyrite content reaches 90 in some ores pyrrhotite content prevails over pyrite by twofold and comprises 50–60 The content of copper fluctuates over a wide range from 0 7 to 3 with zinc content ranging from 0 7 to 3 5 or The.The flotation separation is difficult when lead cop per and zinc need to justify concentration into three perfect separate products Flotation problems in general are due to geological origin hence the ore have controlling influence on flotation practice specifically the resultant copper or lead ions.
