Good evening to all science professionals and appreciative members!
In my case I have a lot of wires and jewelry plated with these 3 metals in the following orders in a brass alloy.
The metal alloy for all parts and wires is golden brass 70% Cu and 29% Zn with very small traces of metals such as Al, Mg, Fe, Mn.
Jewelry and wires with a copper layer on brass;
After this step, I have a Paladium plating undercoat with a final coat of Gold on top.
I have jewelry and threads with a Paladium base and a final layer of Rhodium.
I am used to carrying out gold leaching operations in KCN or NaCn solutions and cementing with Zn or Cu powder to precipitate more noble and less contaminating materials.
And I let the Paladium and Rhodium accumulate in these threads because I don't know what to do to extract and produce sponges with metallic powder.
I want to change this Zn cementation method to the Gold electroextraction and refining method, so I was talking to Deano about his electrowinning cell, he was very enlightening.
But if anyone can guide me better regarding pgm's!
