Spent catalyst from Biji Refining contained valuable metals such as platin. This study focus on platinum extraction in aqua regia solution. Three factors effecting on the process were study including dissolution temperature, normality of aqua regia and agitation speed. The ideal conditions for process give 0.22 gm platinum extraction in dissolution temperature 80 C0, normality for aqua regia was 6 and 120 rpm mixing speed for solution
