玻纤工业用铂铑合金漏板的提纯工艺

摘要

采用了一种从玻纤工业铂铑合金废料中提纯铂铑的生产工艺，对比较纯净的物料，通过物理分离实现铂铑的快速提纯；对于杂质含量较多的物料，采用铂铑不分离工艺，通过化学法去除杂质，提纯的铂铑合金配料熔炼后制造新的玻纤漏板。此工艺实现了铂铑的高效循环利用，缩短了铂铑的回收周期，具有明显的经济效益。%A new process was proposed for recovery of Pt and Rh from platinum-rhodium alloy bushing used in glass fiber industry. Pt and Rh were rapidly purification by physical method for the simple materials, and relatively, the complex materials were purified by chemical method without the separation of Rh and Ir to obtain the platinum-rhodium alloy, which can directly be used to produce new bushing. The process realized the platinum efficient recycling and the production time was reduced leading to obtain a significant economic efficiency.
