从铜阳极泥中提取贵金属,我厂系采用硫酸化焙烧、蒸硒、浸出、还原熔炼、氧化熔炼、电解流程。它的主要缺点是工艺复杂,直接回收率低,劳动条件差,尤其是在贵铅吹炼过程放出大量有害烟气,污染环境,影响工人的身体健康,是生产上亟待解决的一个重要课题。为此,我们参照兄弟单 Extraction of precious metals from the copper anode mud, I plant using sulfuric acid roasting, steamed selenium, leaching, reduction smelting, oxidation smelting, electrolysis process. Its main drawback is the complex process, low direct recovery rate, poor working conditions, especially the release of a large number of harmful fumes in the process of your lead blowing pollution, environmental pollution, affecting the health of workers is an important issue to be solved urgently in production. For this reason, we refer to the brothers list
