This paper describes the experimental investigation on producing blister copper and recovering gold and silver by direct smelting of gold-bearing material.
进行了含金物料直接熔炼粗铜捕集回收金、银的试验研究。
The gold in blister copper sample was pretreated with nitric acid - sulphuric acid to remove copper, digested with aqua , and determined by flame atom absorbance spectrometry.
摘要本文建立了用硝酸硫酸预处理除去大量的铜,王水溶解,火焰原子吸收法测定粗铜中金的分析方法。
粗铜是将上一道 工序产生的含铜60%左右的冰铜进行吹炼,在吹炼炉( 转炉或闪速吹炼炉) 吹炼后含铜约98.5%的铜。其外表 粗糙含 气孔,由此得名,又称“ 泡铜”(英文名:Blister Copper)。 转炉吹炼过程中,粗铜的品位需根据终点判断, 将粗铜品位控制在98%~99%。 这种粗铜再在阳极炉中进行氧化还原后,去除铜内残余的铅、锌、S、铁等杂质后,浇铸成阳极铜板,在 电解槽中生产 电解铜,粗铜中含有的 金 银及一些杂质成分在 阳极下面沉淀,称为“ 阳极泥”,用于 提炼金银。这些金银是和铜 共生的,一般 铜矿都是含有 金银的。
