converted into zinc sulfide by sulfidation roasting. In addition, the content of zinc in the form of sulfate, oxide and silicate also declined after sulfidation roasting, demonstrating that not only zinc in ferrite state but also zinc in sulfate, oxide and silicate states can be converted into zinc sulfide during the roasting. Figure 4 XRD patterns of sulfidation products obtained under different......

of sphalerite concentrate and residues were performed by using JEM-6700F field emission scanning electron microscope. The relationship between the number of recycling and extraction ratio of zinc was studied. The results indicate that 99.6% zinc is obtained after leaching for 3h at 85℃ and pressure of 0.1MPa O2, with 20g sphalerite concentrate in 200mL leaching solution containing 2.0mol/L H2SO4......
