Operation Practice of Putting on Tailing Recovery Zn Ore Dressing on Gold Deposit

Under the influence of polylropic mineral property,low grinding of ore and non-attained-stantard returning water,mineral dressing indices didn′t reach requires of experiment.For this reason,we took some measures,for example,conditioning pulp early,selecting composite inhibitor,finally the mass fraction of Zn of Zn-concentrate amounted to 50%,recovery ration of Zn attained to 80%.
