Flotation recovery of precious metals ScienceDirect

2018-3-1  The valuable metals of Pb and Zn are upgraded in the concentrate as well as the precious metals of Ag and Ge are also significantly beneficiated in the concentrate. The flotation of zinc-lead tailings not only recycle valuable metals of Pb and Zn but also recycle precious metals of Ag and Ge which benefits the economy of forwarding lead-zinc flotation tailings to the repeated flotation process.
