摘要
铜阳极泥酸浸预处理过程中,碲通常以碲化亚铜渣的形式开路,采用硫酸化焙烧—水浸—碱浸—氧化—酸溶—还原工艺处理碲化亚铜渣。结果表明,水浸脱铜率约为90%,碲总回收率为91%~93%,而金、银、铂和钯等在渣中被进一步富集。
Tellurium was usually separated as copper telluride slag in pretreatment process of copper anode slime. Copper telluride slag was treated by processes of sulfating roasting, water leaching, alkaline leaching, oxidation, acid leaching, and reduction. The results show that copper extraction rate is 90%, tellurium recovery rate is 91~93%, and gold, silver, platinum, and palladium are enriched in leached residue.
