中文摘要：

一个直角的数组， L16 (45 ) ，被用来检验四个参数，包括的 NaCl 集中， H2SO4 集中，温度和肉密度的效果在 Cu 的恢复上，在里面，从经由盐水沥滤的 hydrometallurgical 残余的 Pb 和 Zn。结果显示出答案有的沥滤的那温度 Cu 的恢复上的重要效果，在里面并且 Zn，当 H2SO4 集中在这些金属抽取上有明显的影响时。肉密度和 NaCl 集中显著地影响 Pb 抽取。基于直角的数组实验，为 Cu 的抽取的最佳条件，在里面从 hydrometallurgical 残余的 Pb 和 Zn 是 250 g/L， 1.00 mol/L 的 H2SO4 集中， 85 oC 的温度，和 100 g/L 的肉密度的 NaCl 集中。在以这些最佳条件的处理的 1 h 以后，超过 91% 金属从残余被提取。盐水沥滤对从 hydrometallurgical 残余的金属的恢复因此合适。

英文摘要：

An orthogonal array,L16（4^5）,was used to examine the effects of four parameters,including NaCl concentration,H2SO4 concentration,temperature and pulp density,on the recovery of Cu,In,Pb and Zn from a hydrometallurgical residue via brine leaching.The results show that temperature of leaching solution has a significant effect on the recovery of Cu,In and Zn,while H2SO4 concentration has an obvious influence on these metals extraction.Both pulp density and NaCl concentration significantly affect Pb extraction.Based on the orthogonal array experiments,the optimum conditions for the extraction of Cu,In,Pb and Zn from hydrometallurgical residue are NaCl concentration of 250 g/L,H2SO4 concentration of 1.00 mol/L,temperature of 85℃,and pulp density of 100 g/L.After 1 h of treatment at these optimum conditions,over 91% of the metals are extracted from the residue.Brine leaching is therefore suitable for the recovery of metals from hydrometallurgical residues.
