A systematic study on the effects of various minerals and metal ions during ammonia leaching of pure zinc sulphide is reported. The addition of chalcopyrite and sphalerite concentrate to pure zinc sulphide resulted in faster leaching. Various metal ions used for the study were: Cu (I), Cu (II), Pb (II), Ni (II), Fe (II) and Ag (I). Except Ni (II) and Co (II), all other ions displaced zinc from zinc sulfide; Cu(I), Cu(II), Ag(I) and Pb(II) increased the dissolution of zinc sulphide in the order Cu (I) ~ Cu (II) > Ag (I) > Pb (II). Various chemical reactions taking place during exchange and oxidation of zinc sulphide in the presence of metal ions have been suggested.
