Description

一种铜萃取剂
技术领域
本发明涉及冶铜技术领域，具体涉及一种铜萃取剂。
背景技术
湿法冶铜主要指浸出萃取电积法冶铜，该方法包括浸出、萃取、电积三个工艺步骤，其中萃取是该方法的关键步骤，而萃取工艺步骤中最关键的是铜萃取剂的选择。目前冶铜行业使用的铜萃取剂，普遍存在价格昂贵的问题，每吨达16～20万元，而且大部分的铜萃取剂萃取性能较差，不稳定。
发明内容
本发明的目的在于提供一种铜萃取剂。
为了实现上述目的，本发明采用的技术方案为：一种铜萃取剂，含有重量百分含量为20～25％的
Figure G201010300261720100113D000011
10～20％的
Figure G201010300261720100113D000012
10～20％的
Figure G201010300261720100113D000013
其余为溶剂，式中R1、R2、R3为任选被独立地选自C8-C16的直链烷烃基。
其中，所述溶剂为煤油。
在本发明提供的铜萃取剂中，羟醛肟的萃取能力强，反萃能力弱，羟苯乙酮肟和羟苯丙酮肟的反萃能力强，萃取能力弱，这三种组分配合使用，可以达到扬长避短，协同增效的目的。本发明的铜萃取剂萃取性能良好，相分离性好，适应性和稳定性高，能适应生产中工艺参数的波动，而且本发明的铜萃取剂价格低，适合在工业生产中推广使用。
具体实施方式
实施例1
一种铜萃取剂，含有重量百分含量为25％的5-正辛基-水杨醛肟，12.5％的2-羟基-5-正十二烷基-苯乙酮肟，12.5％的2-羟基-5-正十二烷基-苯丙酮肟，其余为煤油。
实施例2
一种铜萃取剂，含有重量百分含量为20％的5-正十二烷基-水杨醛肟，20％的2-羟基-5-正十六烷基-苯乙酮肟，10％的2-羟基-5-正辛基-苯丙酮肟，其余为煤油。
实施例3
一种铜萃取剂，含有重量百分含量为20％的5-正十六烷基水杨醛肟，10％的2-羟基-5-正辛基-苯乙酮肟，20％的2-羟基-5-正十六烷基-苯丙酮肟，其余为260#煤油型溶剂油。
对实施例1～实施例3制得的铜萃取剂进行了萃取性能测试，具体测试数据见表1。从表1数据可以看出，本发明的铜萃取剂萃取性能良好，相分离性好，适应性和稳定性高，能适应生产中工艺参数的波动，而且本发明的铜萃取剂价格低，适合在工业生产中推广使用，应用前景广阔。
