从玻纤工业的熔炉上拆下来的废耐火砖中含有一定量的铂。回收铂铑合金是非常有意义的。上海跃华玻璃厂研究出“火法焙烧—盐酸浸出”提取铂铑的工艺。本所也研究出“砖粉、白云石、纯碱混合焙烧—盐酸浸出法”回收铂铑工艺,每年可从玻纤工业废耐火砖中回收铂铑××公斤。实践证明,上述两种回收铂铑合金的方法均属冶金化学方法,虽然都是可行的,但是由于废耐火砖中的铂铑合金含量一般低于3公斤左右/吨·耐
The waste refractory bricks removed from the furnace of the glass fiber industry contain a certain amount of platinum. Recycling platinum rhodium alloy is very significant. Shanghai Yuehua Glass Factory developed a “fire roasting - hydrochloric acid leaching,” the extraction of platinum and rhodium technology. The Institute also developed a “brick powder, dolomite, soda ash mixed roasting - hydrochloric acid leaching method” recovery of platinum and rhodium technology, fiberglass industrial waste refractory bricks can be recovered annually × × kg of platinum and rhodium. Practice has proved that the above two methods are recovery of platinum and rhodium alloy metallurgical methods, although all feasible, but due to waste bricks platinum and rhodium alloy content is generally less than 3 kg / ton · resistance
