In this video, I am going to show you the full process of silver refining. It takes 1 day to complete the whole process for silver refining. The same technique can be used to extract the silver used in the gold refining process. The silver alloy contains many metals like zinc, copper, lead, etc. To extract silver we used a copper plate. The silver will start forming on the surface of the copper when the solution (silver nitride) touches the surface. KARAT METER Testing Machine is used to test the purity of gold and silver
Procedure to Refine Silver
1. Melt silver alloy into small pieces
2. Put the small alloy pieces into a steel container
3. Use Nitric Axid to start the reaction between alloy and the acid
4. Supply nitric acid to the steel container continuously until the alloy gets dissolved into acid
5. When the reaction starts it produces red smoke so wait till it produces white smoke
6. White smoke represents the end of the chemical reaction
7. Wait for 12 Hours
8. Pour the solution into another vessel containing water and copper plates
9. Use a water-salt solution to check the concentration of silver into the alloy solution
10. Stir the solution till all the silver gets formed
11. Remove all the silver from the vessel then melt into a crucible
12. 99.99% Silver has been Recovered
