  • A fundamental study of the reductive leaching of ...

    A chalcopyrite concentrate containing around 60% chalcopyrite and analyzing around 28% copper was leached under reducing conditions using metallic iron. Various parameters were studied to understand their effect on leaching kinetics, including : temperature, particle size, agitation, acid concentration, molar ratios, and others.

    2020-6-17  The sphalerite concentrate used was provided by Zhuzhou Smelter, Hunan, China. Prior to leaching, the concentrate was treated with Na2S solution to clean and sulfurise the surface of the mineral. Chemical analysis shows the concentrate containing (wt %) Zn 53.12, Fe 9.58 and S 31.94.
