Description
技术领域
本发明涉及铜冶炼技术领域,具体涉及一种适用于铜阳极泥中硫酸钡渣处理的工艺。
背景技术
铜冶炼厂采用硫酸钡作为阳极板的脱模剂,由于机械夹带等多种因素的影响,一部分脱模剂硫酸钡与铜阳极板一同进入铜电解,在铜电解过程中,硫酸钡渣不溶于硫酸,又以铜阳极泥的方式进入稀贵厂,稀贵厂将铜阳极泥脱铜处理后,由于硫酸钡渣属于高熔点物质,在卡尔多炉熔炼过程中难以熔化,且比重大,不利于卡尔多炉熔炼工艺造渣工艺控制。当前,为了有效降低硫酸钡渣的加入对卡尔多炉熔炼工艺的影响,在进入卡尔多炉前,通过分级沉降等方式分离出硫酸钡渣,按照年处理3000t阳极泥的规模,稀贵厂年产生硫酸钡渣150-200吨。
该硫酸钡渣中含有一定量的金银及铋、锑、钯等稀散元素,其中含金50-200g/t,银500-6000g/t、铜0.2%-0.9%,铂1%、钯1%-4%、钡45%,粒度粗,呈砂粒状,+160目所占比例约占88.7%,比重较大(真比重达4.396),现有的处理方式是返回渣选矿厂与闪速炉炉渣和转炉渣一道经球磨后进入浮选***,最终以渣选铜精矿的方式进入闪速炉,但由于硫酸钡渣比重大、沉降速度快,且由于硫酸钡渣中金银主要以熔融体的方式与硫酸钡渣粘附在一起,难以被有效浮选,浮选回收率低,金银等有价元素品位较高,导致有价元素损失大,不利于硫酸钡渣中有价元素的综合回收,且整体流程较长,资金回笼慢,金银回收周期达25-35天。
发明内容
针对现有技术的不足,本发明旨在提供一种适用于铜阳极泥中硫酸钡渣处理的工艺。
为了实现上述目的,本发明采用如下技术方案:
一种适用于铜阳极泥中硫酸钡渣处理的工艺,具体过程为:
S1、硫酸钡渣经带滤机逆流洗涤至呈中性后,所得的洗液进入步骤S2,所得的洗涤渣进入步骤S3;
S2、步骤S1所得的洗液利用萃取电积工艺生产高纯阴极铜;
S3、步骤S1所得的洗涤渣采用氰化贫液调浆,利用球磨机细磨,球磨后矿浆采用氰化贫液进行多段浸出;浸出液中的金银采用锌粉置换-硝酸分银的精炼工艺回收,最终得到的浸出渣在自然风干降低水分后,配入铜精矿进入铜火法熔炼***进一步富集回收铂钯。
进一步地,步骤S3中,利用球磨机细磨至-325目占90%-95%。
进一步地,步骤S3中,浸出中,控制液固比L/g为3:1,用碳酸钠调pH至10-11,矿浆质量浓度控制在20%-25%,NaCN质量浓度控制在3‰。
进一步地,步骤S3中,多段浸出5-7次,每次浸出10-24h。
本发明的有益效果在于:本发明通过氰化浸出—锌粉置换—金银精炼的湿法工艺,可以实现较高的金银回收率,且该部分金银可在10天内回收,回收周期短。浸出渣返回铜火法熔炼工艺,金和银的总回收率进一步提升,且可综合回收铂钯。本发明具有成本低、回收率高、回收周期短的特点。
具体实施方式
以下将对本发明作进一步的描述,需要说明的是,本实施例以本技术方案为前提,给出了详细的实施方式和具体的操作过程,但本发明的保护范围并不限于本实施例。
本实施例提供一种适用于铜阳极泥中硫酸钡渣处理的工艺,具体过程为:
S1、硫酸钡渣经带滤机逆流洗涤至呈中性后,所得的洗液进入步骤S2,所得的洗涤渣进入步骤S3;
S2、步骤S1所得的洗液利用萃取电积工艺生产高纯阴极铜;
S3、步骤S1所得的洗涤渣采用氰化贫液调浆,利用球磨机细磨至-325目占90%-95%,球磨后矿浆继续采用氰化贫液控制液固比L/g为3:1,用碳酸钠调pH至10-11,矿浆质量浓度控制在20%-25%,NaCN质量浓度控制在3‰,多段浸出5-7次,每次浸出10-24h;浸出液中的金银采用锌粉置换-硝酸分银的精炼工艺回收,最终得到的浸出渣在自然风干降低水分后,配入铜精矿进入铜火法熔炼***进一步富集回收铂钯。需要说明的是,每次浸出后经洗涤过滤得到的浸出渣进入下一阶段的浸出。
通过上述的氰化浸出—锌粉置换—金银精炼的湿法工艺,金、银的回收率分别可高达95.6%、98.3%,且该部分金银可在10天内回收,回收周期短。浸出渣返回铜火法熔炼工艺,金和银的总回收率进一步提升至99.75%、99.82%,且可综合回收铂钯,具有成本低、回收率高、回收周期短的特点。
对于本领域的技术人员来说,可以根据以上的技术方案和构思,给出各种相应的改变和变形,而所有的这些改变和变形,都应该包括在本发明权利要求的保护范围之内。
