含铂、钯、铑、铱等粉末废料的处理,根据物料的不同,可采用王水浸出(包括固体盐生成的王水—dry aqua regia)、氧化碱融,硫酸浸出、氨浸、氯化、电溶及火法等。最早把氯化法成功地用于提取铂族金属是Schneiderhohn,而此法通常只处理含铂钯矿或浓缩低品位的铂族金属物料(阳极泥)。据Liska·k等最近报道对这种 Disposal of waste materials containing platinum, palladium, rhodium and iridium, depending on the material, may be carried out using aqua regia (including aqua regia produced by solid salts), alkali oxidation, sulfuric acid leaching, ammonia leaching, chlorination , Electrolytic and fire method. The earliest successful chlorination of PGMs was Schneiderhohn, which usually only treats platinum-bearing palladium or concentrated low-grade PGMs (anode slime). According to Liska K. and others recently reported on this
