铜阳极泥选冶富集金银的粗选研究

铜阳极泥含有大量的贵金属和稀有元素，是提取贵金属的重要原料。对铜阳极泥原料进行预处理后，用自制的不同浮选捕收剂以选冶工艺流程分离富集贵金属，考察了不同条件铜阳极泥的浮选行为。结果表明，经预处理后，采用自制药剂C，pH控制在2时进行粗选，粗选精矿中金、银的富集比接近4.5，银品位达到45%~50%，金品位由0.2%提高到0.8%~1.0%，可直接熔铸成板，节省了传统工序的贵铅炉熔炼并降低了成本，有利于后续处理。

The Rougher Flotation Process of Copper Anode Slime for Collecting Gold and Silver

The copper anode slime, which contains a lot of precious metals and rare element, is an important raw material for the recovery of precious metals. The rougher flotation process of copper anode slime, applying some home-made collectors, was discussed, which followed by a pre-treatment process. And different operating conditions were studied in detail. The results showed that, after pre-treatment process, if the home-made collector C had been used and pH value controlled at 2, then the grade of gold and silver in flotation concentrate would reach 0.8%~1.0% and 45%~50%, respectively. And the concentration ratios of precious metal can achieve 4.5. The flotation concentrate will be allowed to turn into the smelting process directly, saving the traditional process of lead smelting and reducing the cost, which is helpful for subsequent processing.
