对合金银的锌渣浸出时产生的滤渣,如果用湿法处理,贵金属则分布在处理产品之间.这样使工艺复杂化,也降低贵金属回收率.代替湿法冶金的另一种方法就是火法冶金.试验时,把铁渣和金属铜—冰铜作为贵金属捕收剂与含锌滤渣一起溶化.试验是在感应炉内进行.感应炉的坩埚容积为3.5L.熔化前,一部分滤渣加以950℃的死烧.按一定的比例往坩埚中装入回炉渣、金属铜和滤渣.试验结果表明,达到以下回收率:铜9.7%,金100%;银96%试验表明,金
The leaching residue of the dross of the alloyed silver dross, if treated wet, will distribute the precious metal between the treated products, complicating the process and reducing the precious metal recovery Another alternative to hydrometallurgy is fire In the test, the iron slag and the metallic copper-matte were melted together with the zinc-containing filter residue as a precious metal collector.The test was carried out in an induction furnace with a crucible capacity of 3.5 L. Before melting, a portion of the filter residue 950 ℃ .According to a certain proportion of the crucible into the furnace slag, copper and residue.Experimental results show that the following recovery: copper 9.7%, gold 100%; 96% silver test shows that gold
