Purification of solution prepared by leaching spent battery material
With shortage of raw resources and constraints of circumstance protection,it is more and more important to recycle nickel,cobalt and manganese from spent battery material.This work introduces a method of recovery of Ni,Co and Mn from polymetalic solution which is characterized by medium to high concentration of residual hydrochloric acid and heavy metals such Cu,Ni,Co,Mn,Fe and prepared by leaching spent battery material.The basic concept includes copper is removed through replacement by iron powder followed by iron precipitation in goethite method.The results show that Cu can be removed 99% at least through replacement by Fe powder,and the removal of Fe can achieve 99% by goethite method.At the same time ,the loss of Ni,Co and Mn are about 2%,3% and 2%,respectively.The optimun Cu removal conditions are :T=50℃,Fe mol/Cu mol =1.5,reaction time =30 min.The optimum Fe removal conditions are :precipitation terminal pH =4,T=90℃,reaction time =6 h.This method can be economic to prepare pure solution for preparation of NixCoyMnz ternary system precursor.

利用废旧电池制备提纯溶液
由于矿产的稀缺和资源循环利用的局限性,回收旧电池中的镍、钴和锰就变得越来越重要.这种回收工作就提到了一种方式,即从中高浓度的盐酸,包含诸如铜、镍、钴、锰、铁等重金属和废旧电池混合的金属溶液中提取镍、钴和锰.其中的基础理论包含了用铁粉从溶液中置换铜和铁以针铁石形势沉降的方法.结果证明,这两种方法对于铜的回收率达到99%,而铁的回收率也可达到99%.与此同时,镍、钴和锰各自的流失率分别为2%、3%和2%.置换铜的最适宜条件:50℃,铁与铜的摩尔比为1.5,反应时间为30分钟.沉降铁的最适宜条件:沉降终点PH值为4,90℃,反应时间为6小时.以上的方法在准备镍x钴y锰z的三元系统纯溶液时也十分的经济和方便.
翻译的很多地方不很贴切和通顺,您再参考参考别人的翻译吧~
