If I cement out a solution of various rhodium, platinum, palladium, magnesium, zinc, and iron chlorides by using copper, I should in theory, drop out all metals below on the reactivity series (Pd, Pt, Rh)
After proper washing, and perhaps a round of redissolution/recementation, is it practical to melt those metals into a bead, and confirm with XRF analysis? Will Pd, Pt, and Rh melt together, and be verifiable to a semi-accurate scale with the XRF gun? Or will I need to further seperate them in order to melt them all together? I may have missed it in Hoke: I want to be able to melt a sample of all of them into a bead and have it scanned at the local jewelry shop, and I’m not sure if it will give an accurate depiction of the % contents. I’m aware that powder will not produce accurate results with XRF. I plan to use a wesgo crucible, OXY-propane, and borax flux.
Please show me grace here, I am a newbie with thousands of hours of research, and very little laboratory experience related to PGMs. Due to their hazardous nature, I want to fill my brain with information and carefully plan, prior to jumping in. I’ve been reading books, forum posts, and articles for 6 years and haven’t even touched the material in this timeframe.
