| Abstract: |
| To obtain the appropriate conditions for eliminating Fe3 from NiSO4 solution, the digestion solution of the clinker was used as raw material, which was obtained from roasting the nickel oxide ore with (NH4)2SO4. and Na2CO3 as alkaline regulator, the wet chemisty method was prepared the ammonium jarosite(Na2Fe6(SO4)(OH)12). The optimum technological conditions are reaction temperature at 95℃, reaction time at 4h, the end pH level at 2.5, the iron removal rate over 99.5% under the optimum conditions. The XRD、SEM and componebts analysis were used to characterize the decomposition product. The Na2Fe6(SO4)(OH)12 with regular cluster figure is composed of sheet particles with smooth surface. |
