AI Thread Summary
Rhodium recovery from ore can be effectively achieved by using a 40% sulfuric acid (H2SO4) bath at 40°C after grinding the rhodium-containing materials. This process involves diluting the materials in the acid solution to dissolve the rhodium. Following this, a galvanic process is employed to deposit the rhodium onto a titanium cathode. This method highlights the importance of both chemical solubility and electrochemical techniques in rhodium recovery. Efficient recovery processes are crucial for maximizing rhodium yield from ore.

Rhodium recovery process from ore
 
Engineering news on Phys.org
Hello Dr Courtney,
since Rhodium is soluble in H2SO4, I would dilute the materials Rhodium containing after grinding in an 40% H2SO4 bath at 40°C and then over an galvanic process removing from the solution onto a Cathode from Titanium.
