摘要
采用选矿和冶金联合工艺从玻纤浇注料中回收铂和铑。首先采用重力选矿法使玻纤浇注料中90%~93%的铂铑得到初步富集分离,得到品位为60%~80%的铂铑精矿和尾矿,低品位尾矿采用Na2O-Al2O3-SiO2低熔点渣系,通过铅熔炼捕集、吹炼除铅工艺产出铂铑富集物料,然后通过精炼得到合格的铂铑金属产品。结果表明,全流程铂和铑的回收率分别大于99%和98.5%。
Palladium and rhodium were recovered from glass fiber castable by henefication-metallurgy com- bination process. Pd and Rh with grade of 90%-93% in glass fiber castable was preliminary enriched by gravity concentration and palladium and rhodium concentrates with grade of 60%-80% were obtained. The low grade tailings were smelted with lead as collector in Na2 O-Al2 O3-SiO2 slag system and then blown with air to produce Pd and Rh concentrates after lead was removed. Pd and Rh qualified metal products were gained by concentrates refining. The results show that total recovery of Pd and Rh is over 99% and 98.5 % respectively.
