Description
技术领域
本发明属于稀贵金属冶金技术领域,具体涉及一种从合金吹炼转炉烟道灰中分离银、硒和碲的方法。
背景技术
目前从铜电解产出的铜阳极泥中综合回收金银硒产品的主流工艺是采用“铜阳极泥加压浸出-合金吹炼及硒回收-大极板银电解-水溶液氯化-亚硫酸氢钠选择性还原金-氧化还原精炼硒—废水处理”的处理工艺,能够产出符合国家标准IC-Au99.99,IC-Au99.99,Se99.9。
在合金吹炼转炉检修过程中,会对烟道进行清理,保证烟道的负压,确保硒吸收效果,清理烟道得到的烟道灰中含有银、硒、碲等稀贵金属,具有回收价值。然而烟道灰比重较小,作为返料进入合金吹炼转炉熔炼、吹炼时容易随烟气冒出再次形成烟灰,能有效进行熔炼的部分较少,且再次形成烟灰易造成烟尘回收系统堵塞,从而造成恶性循环,频繁清理烟道,劳动强度大,银、硒、碲的回收率较低。为此,开发一种从合金吹炼转炉烟道灰中分离银、硒和碲的方法显得极为重要。
发明内容
本发明所要解决的技术问题是针对上述已有技术存在的不足,而提供一种从合金吹炼转炉烟道灰中分离银、硒和碲的方法,实现合金吹炼转炉烟道灰的开路处理,具有工艺流程短,银、硒和碲的回收率高,生产成本低,经济效益高的特点。
本发明目的是通过以下技术方案实现的:
一种从合金吹炼转炉烟道灰中分离银、硒和碲的方法,包括以下步骤:
(1)将烟道灰按照液固比4:1,酸度120-150g/L,温度150-170℃,釜压0.8-0.9MPa的条件进行加压浸出,通入氧气反应3-6h,使碲和硒浸出到溶液中,而银进入浸出渣中;
(2)加压浸出渣进入合金吹炼转炉经过熔炼、吹炼产出含银大于96%的银阳极板,再经过银电解产出99.99%的银粉,加压浸出液加热至80-85℃,加入NaOH溶液碱调节pH=4-5后搅拌反应2-4h,静置2-5h后过滤,得到二氧化碲和沉碲后液;
(3)沉碲后液降温至60-65℃,加入硫化钠进行净化至pH=7-8反应结束,对净化后液加入硫酸调节pH=5-6,加入水合肼还原净化后液终点控制在pH=8-9得到含硒大于96%的粗硒。
所述步骤(1)中氧气的通入量是30-35Nm3/h。
本发明涉及一种从合金吹炼转炉烟道灰中分离银、硒和碲的方法,合金吹炼转炉烟道灰经加压氧化酸浸得到加压浸出渣和加压浸出液,加压浸出渣经合金吹炼转炉熔炼、吹炼产出含银大于96%的银阳极板,银阳极板经银电解产出99.99%的银粉。加压浸出液经NaOH溶液调节pH进行沉碲,得到二氧化碲。沉碲后液降温加入硫化钠进行净化,对净化后液加入硫酸调节pH使用水合肼还原得到含硒大于96%的粗硒。本发明的优点在于湿法和火法并举工艺,实现合金吹炼转炉烟道灰中银、硒、碲的分离与回收,具有工艺流程短,分离效率高,加工成本低,银、硒、碲回收率高,能够产出99.99%银粉、二氧化碲和含硒96%以上的粗硒。
