, China) Abstract: A new sulfide mineral collector, N-butoxypropyl-N′-ethoxycarbonyl thiourea (BOPECTU) was introduced, and its reaction with metal ions such as Cu2+, Zn2+, Fe3+ or Fe2+, its flotation performance to chalcopyrite, pyrite or sphalerite, and its adsorption mechanisms on the three sulfide mineral surfaces were investigated. The results show that BOPECTU reacts chemically with Cu2+ through......
