Help Support Gold Refining Forum:
hello everybody,this is my forst post on this wonderful forum,i guess nightmare asked where he can get rhodium?and the topic has lost track,suggesting stock exchange prices etc.....anyway i m curious to know from nightmare,do u want to recover rhodium from scrap?because this is something even i wish to know,i see a lot of jewellery going into the furnance for refining,and nobody pay heed to the rhodium plated on it.
can somebody guide how to recover plated rhodium from gold or other jewellery? steel rods which are used as artificial bone replacements are also thickly rhodium plated,once these rods are removed from bodied,they become medical wastes and reach junk yards.
i wud really appriciate anybody pointing me and probabely nightmare too,to relevent topic,if it has been discussed before on this forum.
nightmare if your question was different from what i have precieved,then pls elaborate more on it,so that this community may help you.
regards.

Most of the Rh plating I collect is from sterling silver jewelry. It's easily recovered by digesting the silver in 35% nitric acid. The Rhodium plating stays behind as flakes of bright silver colored foils.
For gold plated with Rhodium inquart, extract the silver with 35% nitric acid (HNO3), and dissolve the solids in dilute hot AR. Most of the Rh should remain behind as an undissolved fine gray powder.
Use the search feature to learn more about testing and refining Rh.
Here's what the foils from Rh plated silver will look like:
