Abstract

En 中文

• The selective inhibitory mechanism of CME with Cu2+ was studied. • The flotation separation of sphalerite and pyrite has been achieved. • CME can adhere to the surfaces of pyrite forming a hydrophilic film. • The Cu2+ selectively adsorbed on sphalerite surface and activated the sphalerite.
