; Abstract: A dual cell system with chalcopyrite anode and MnO2 cathode was used to study the relations between time and such data as the electric quantity and the dissolution rates of the two... faster than those in EGL, and nearly 3 times for Mn2+; the electric output increased nearly by 3 times. The oxidation residue of chalcopyrite was represented by TEM and XRD, whose pattern was similar......

thiooxidans were investigated, and then experiments were conducted to research the bioleaching behaviors of crude ore of copper sulfide and hand-picked concentrates of chalcopyrite by Acidithiobacillus.... The bioleaching rates reach their highest point in sulfide copper and chalcopyrite with a pulp density of 5% and 10%, respectively. Column flotation experiments of low-grade copper sulfide ores show......

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 its S and N atoms to form a new chelate compound, but no reaction of BOPECTU with Zn2+, Fe3+ or Fe2+ is observed under the same test conditions. BOPECTU is an excellent collector for chalcopyrite......
