Wet air oxidation process is one for treating spent special steels pickling liquor to recover acid in an indirect way acid and valuable metals. In the process, first step is taken by making use of free acid in spent liquor to dissolve waste slag obtained during special steel processing. Thus, overall acidity of the spent liquor is reduced and recovery of valuable metals are augmented. Then wet air oxidation is conducted by introducing compressed air into the s... 本方法首先利用废液中的游离酸溶解特殊钢加工过程中产生的废渣,然后采用空气氧化法,在pH4—5,70—80℃,晶种存在条件下,通压缩空气进行氧化,分离废液中的铁、铬和镍、钴,并回收镍、钴.国内外资料中尚未见到此方法. 文摘来源 The electrostatic pseudo liquid membrane separation process, developed recently in this laboratory, is a novel chemical separation technology. It is an inter-disciplinary technique evolved from the combination of solvent extraction, liquid membrane and electrostatic techniques. It can be used to separate, purify and concentrate specific solutes from aqueous solutions. Therefore, it is suitable for the recovery of valuable metals from aqueous solutions in the field of hydr... 静电式准液膜分离技术是由本实验室最近发展起来的一种新型化工分离技术,它是在溶剂萃取、液膜和静电技术的交叉点上产生的边缘技术.该技术能用于分离、纯化和浓缩水溶液中的特定溶质,适用于水法冶金过程中(包括核燃料循环)从水溶液中提取有用金属,并适用于废水处理等过程.本文讨论了这一新型分离技术的基本原理,并以D_2EHPA萃取Co~(2+)为例,研究了电场强度、萃取剂浓度以及料液与反萃液的流比等对金属提取率的影响.实验表明,Co~(2+)的一次提取率可达99%以上,与此同时,浓缩液中的Co~(2+)可以一次浓缩至40—50g/L. 文摘来源 The research on low-contaminant jarosite process of zinc hydrometallurgy is described in this paper. A comparison is made between the research results in our institute and those in Risdon plant in Australia. The problems are discussed on the advantages of this process and the recovery of valuable metals. 本文研究了低污染铁矾法炼锌工艺过程,并将研究结果同澳大利亚Risdon厂的结果进行对比,讨论了低污染铁矾法炼锌的效益和铅、银回收。 文摘来源 << 更多相关文摘
