low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 91 95% recovery was produced utilizing a high pH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of Zn of the ore body, a Cu/Zn separation circuit was initiated in early 2010 following an intensive laboratory test work program. This Cu/Zn

Galmoy Mine, owned by Arcon Mines Limited, has operated since 1997, and is one of three operating lead/ zinc mines in Ireland. Changes in ore
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
The experimental data on copper zinc ore flotation have shown that sphalerite and pyrite present at the final process stages of col lectiveselective flotation possess equal kinetics of floatability. This is particularly obvious in zinc flotation cycle, where pyrite is only depressed with lime and blue copperas activates both sphaler ite and

Iron sulfide (pyrite, pyrrhotite, marcasite) depressant used in the flotation separation of base metal sulphides. Also used as an alternative partial cyanide replacement to depress iron and zinc sulfides in Pb / Zn flotation. UNIMAX 174; SD210. Iron sulfide (pyrite, pyrrhotite, marcasite) depressant used in the flotation separation of base metal sulfides.
The depression of gold flotation by zinc cyanide was due to the Since this is a pyrite dominant ore, the flotation recoveries of Fe and S presented in Fig. 1 are
the activation of sphalerite with copper sulphate (CuSO4) and its flotation in the zinc circuit, while pyrite is depressed at high pH with lime. The metallurgical performance and reagent suite of the plant during the earlier days of operation are given in Tables 2.1 and 2.2, respectively (Watson and Botha, 1983). Currently, ore from the western
