【摘要】 <正> 本文采用加铂钯混合物的铅试金法对矿石中铑铱的富集进行了系统的研究。确定了加入6mg铂和4mg钯的铅试金法富集硫化铜镍矿中铑铱最好,铑铱的标准回收均达90％以上。50g矿样中含金量<10mg、含银量<5mg不干扰铱的富集;含金量<100mg、含银量<10mg不干扰铑的富集。较好地解决了矿石中铑铱的富集问题。国内外一些试金分析工作者曾用加金、钯、铂、铂金混合物的铅试金法富集矿石中的铑更多还原

【Abstract】 A systemic study has been made on concentrating Rh and Ir in ores by lead assay with adding a mixture of platinum and palladium. The test shown that the mixture of 6 mg Pt and 4 mg Pd is the best choice. Standard recoveries of Rh and Ir are more than 90%. A prodecure was developed and simplified, and has been successfylly applied in some metallurgical factories due to its high efficiency of concentration.更多还原
