从含铜、银、金、铂的金属废料中提取银、金、铂,首先是除铜,其后再进行银、金、铂的分离。1.除铜(1)电解金属废料经必要的清洗后,熔化成棒为阳极,纯铜板为阴极,置于已加入硫酸的硫酸铜溶液,控制一定的电压与电流密度进行电解,合金中的铜在阳极溶解,并得到含银、金、铂的阳极泥。 Silver, gold, platinum from the metal scrap containing copper, silver, gold, platinum, the first is in addition to copper, followed by silver, gold, platinum separation. 1. In addition to copper (1) after the necessary cleaning of electrolytic metal scrap, melted into rods for the anode, pure copper cathode, placed in sulfuric acid has been added sulfuric acid copper sulfate solution to control a certain voltage and current density for electrolysis, the alloy Copper dissolves at the anode and gives anode slime containing silver, gold and platinum.
