中文摘要: 为得到硫酸镍溶液除铁的工艺条件,以低品位红土镍矿硫酸铵焙烧熟料溶出液为研究对象,Na2CO3为碱试调节剂,采用湿化学方法制备黄钠铁矾。造矾最佳条件为:反应的温度95℃、反应时间4 h、终点pH值2.5,除铁率在99.5%以上,并采用XRD、SEM和化学分析手段对黄钠铁矾进行了表征。在此条件下所得到的黄钠铁矾为外形规则的,包含多个光滑颗粒的花簇结构。
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.
