Abstract: Malachite sulfidization-flotation tests were carried out in Hallimond Tube.(NH4)2SO4.was added to test its anti-depression function at the presence of an excess amount of Na2S and the surface morphologies of pure malachaite minerals were investigated by SEM at various test conditions.The results shows that, in a malachite flotation system with excessive amount of Na2S,NH4)2SO4 , when added to the system, can play a role of anti-depression.It will make the sulfide film formed on the surface of malachite firmer, denser and more stable, facilitating the adsorption of xanthate.

Key words: Oxide copper ore, Malachite, Anti-depression function
