In this video, I am going to show you the full process of silver refining using salt and irons nails and iron round sheet. It takes 2-3 hours 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 will start forming when we add water-salt solution to the reaction output (silver nitride). 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 Acid 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. Add water-salt solution to the by-product produced in the chemical reaction and as soon as we add the solution it will start forming silver powder

8. Add Iron Nails and Iron Sheet and stir them till the silver powder will be converted into metal sand

9. Dry the silver metal sand and melt them into a crucible

10. 99.99% Silver has been Recovered

11. Check the Silver Purity in Metal Testing Machine (Karat Meter)
