Description
技术领域
本发明涉及一种高铋铅阳极泥的处理工艺,属于有色重贵金属冶金领域。
背景技术
铅阳极泥是粗铅电解精炼时的一个副产品,它是生产金银等贵金属的一个主要原料,同时也是回收铋锑铜碲等有价金属的一种主要原料,其中含铋的铅阳极泥是生产精铋的主要原料,含铋铅阳极泥传统的处理方法是将阳极泥用反射炉(或转炉)还原熔炼成贵铅,然后把贵铅在转炉氧化吹炼产出粗银和铋渣,粗银送银电解精炼,产出白银黄金等,而铋渣利用小鼓风炉等炉窑还原熔炼成粗铋,粗铋再经过多个工序的火法精炼产出精铋。传统的工艺虽有设备投资少,上马快,操作方便的优点,但该工艺产出的粗铋主含量低往往只有50-70%,火法精炼时工序多,生产周期长,铋的直收率低,往往只有30-40%,精炼渣量大,滞留的有价金属量多,占用的资金多,生产成本高,所以国内外大多数企业已不用该工艺生产。
2007年12月05日,中国发明专利申请公布号CN101082084A ,公布了(杨跃新等人)从铋渣中回收冶炼精铋的工艺,该工艺是先湿法后火法方法回收转炉铋渣中的铋,即将转炉产出铋渣用机械粉碎后用盐酸溶液浸出,铅金银与铋铜分离效果好,粗铋质量好,易于精炼等优点,但湿法工艺生产线长,操作要求高,同时产出大量的氯化钠溶液需要蒸发导致能源消耗高,生产成本高。
“从阳极泥中回收铋新工艺生产实践”,任建民、黄宪涛等,《中国金属通报》,第24卷,第3期,第42-43页,2017年)介绍了从阳极泥中回收铋新工艺情况,该工艺实际上亦是将铅阳极泥还原熔炼或贵铅,贵铅在分银炉中氧化吹炼产出氧化铋渣,氧化铋再经还原熔炼产出粗铋,粗铋再经除铜,除铅等工序后进行真空蒸馏,蒸馏产物再经高温精炼产出精铋。该工艺前段与传统工艺完全相同,只是在粗铋精炼时用真空蒸馏代替了加锌除银工艺,因此该工艺仍然存在精炼渣量大,滞留有价金属多,铋的直收率较低,生产成本高问题。
发明内容
为了克服上述工艺的不足,本发明提供了一种高铋铅阳极泥的处理工艺,该工艺具有流程简单,生产效率高,周期短,有价金属综合回收率高,加工成本低等特点。
本发明一种高铋铅阳极泥的处理工艺,包括以下步骤:
a高铋铅阳极泥的富氧还原熔炼
所述高铋铅阳极泥含Bi≥8.0%,含Ag5000-60000g/t,Bi:Pb 0.5-5.0;采用富氧熔炼,强化了熔炼过程,提高了效率,在熔炼过程控制适当条件,使绝大部分铋和金银及部分铅铋进入贵铋中,绝大部分锑进入烟尘中,大部分铅进入氧化铅渣中,逐步实现铋和金银与铅锑的分离;
b贵铋的真空蒸馏
利用铋与金银几种金属的沸点差异,在接近真空的状态下控制合理的温度使贵铋中的铋、铅、碲优先挥发出来,金、银和铜金属在残留的合金中,经过真空蒸馏,分别得到粗铋、毛银与碲渣;碲渣和粗铋分别送碲回收车间和铋精炼车间生产精碲和精铋,毛银则送分银炉吹炼,产出粗银和铋渣;
所述贵铋的真空蒸馏包括一次蒸馏、二次蒸馏和三次蒸馏,温度控制一次蒸馏950-1050℃,二次蒸馏900-950℃,三次蒸馏800-900℃,真空度3-10Pa;
c铋渣的还原造锍熔炼
贵铋真空蒸馏产出的毛银经转炉氧化吹炼后,得到粗银和氧化铋渣;由于铋渣中含有较高的铜,铋渣投入转炉中进行还原造锍熔炼,利用硫对铜的亲和力大的特性熔炼时加入硫精矿,铋渣中的铜以硫化物的形式进入冰铜渣中,而铋渣中的铋则被还原进入第二贵铋中;第二贵铋返回真空蒸馏;冰铜渣送氧压浸出和铜电积工序得到阴极铜产品和浸出渣,浸出渣也称铅银渣,返回铅系统回收金银铅金属;
所述的还原造锍熔炼,还原煤率2-5%,硫精矿率8-18%,炉温1250-1300℃。、
所述富氧还原熔炼适当条件是:还原煤率1-5%,氧气浓度92.5%-99.5%,氧压0.15-0.6Mpa,炉温900-1100℃。
所述的烟尘是粗锑白。
所述第二贵铋返回真空蒸馏是:铋渣还原造锍熔炼产出的第二贵铋与a步骤产出的贵铋一道进行真空蒸馏。
本发明具有流程简单,生产效率高,周期短,有价金属回收率高,生产成本低等特点。
