Abstract
The present article introduce a method of pyrometallurgy to recovery platinum from spent auto-catalysts. In the paper, the effect of binary basicity R (R=CaO/SiO2) of slag and the parameters of smelting process such as temperature and time of smelting on platinum recovery were researched. The results of this study show the platinum recovery is higher when R should be around 0.5 and smelting temperature of 1773 K as well as smelting time of 4 hours. Under the optimum condition, the recovery rate of platinum is up to 98% by the method presented.
