摘　　要：根据某铜冶炼企业铂钯精矿的特点,钯提纯工艺设计为"洗矿→盐酸酸浸除杂→氯化浸出→亚硫酸钠还原金→铂钯沉淀→铂钯分离→钯还原",铂提纯工艺设计为"氯铂酸铵还原→氯化浸出→氯化铵沉铂→煅烧",并进行提纯工艺匹配设备选型与产业化设计,在生产实践基础上进行经济效益简析。结果表明,铂、钯回收率分别为95.0%、98.5%以上,年可回收12.0 kg铂粉、107.6 kg钯粉,年增加收益达6 158万元,年投资成本约67万元,项目经济效益显著。According to the characteristics of platinum-palladium concentrate in a copper smelting enter-prise,the palladium purification process was designed as“ore washing→acid leaching→chlorination leaching→sodium sulfite reduction gold→platinum and palladium precipitation→platinum and palladium separation→palladium reduction”,and the platinum purification process was designed as“ammonium chloroplatinate reduction→chlorination leaching→platinum precipitation by ammonium chloride→calcina-tion”.The selection of purification equipment and industrial design were made,the economic benefits were briefly analyzed.The results showed that the recovery rates of platinum and palladium were more than 95.0%and 98.5%,respectively.The process can recover 12.0 kg platinum powder and 107.6 kg palladium powder per year,the annual increase income was 61.58 million yuan,and the annual invest-ment cost was about 0.67 million yuan.The economic benefit of the project was remarkable.
