I want to refine 99.9% of palladium ingot to make more than 99.95% palladium spoge. The main impurities are iron and silicon. What kind of leaching solution( i thick nitric acid) to create a sponge? What other solution (ammonia?)should I mixed? I would appreciate your suggestions for this process. iron & silica are about 500ppm, 300ppm.
