废旧首饰中铂族金属回收
recovery of platinum group metal from jewelry scrap
fe,J iu shoushi zhong bozu Jinshu huishou废旧首饰中铂族金属回收(reeovery of pla-tinum group metal from jewelry serap)从废旧首饰中进行铂族全属再生的过程。铂首饰主要使用含铂90%的铂基合金,如R一10Ir、R一SRu等。全世界首饰用铂逐年增加,199。年占铂消耗量的37.3%。旧首饰较为纯净,无需经过复杂的处理即可重新加工成首饰出售。首饰制作过程中产生的边角料和粉尘,杂质少,回收工艺也较简单。这些废料通常经熔炼、溶解使铂族金属和杂质分离后,送铂族金属精炼产出纯金属。熔炼铂铱合金废料时常需添加锌(或锡)进行碎化后再溶解,再按合金废并中铂族金属回收方法处理。含钉首饰废料用王水溶解,氧化蒸馏法分离钉和铂(或把),四氧化钉蒸气用盐酸加乙醇吸收后,用氯化按沉淀,所得(NH;)3RuCI。在氢气中锻烧得海绵钉。蒸馏残液中的铂或把用铂精炼或把精炼方法回收。 (李关芳)
