MLCC Capacitors

Lead Extraction:

All metals have become one piece. Make pot with sodium bicarbonate and Ash using 50:50 ratio. Put the metal piece in a pot and start giving heat until metal piece melt. Give twist, again and again, steel rod until some extra metals start floating. Take out all floating metal and leave it with medium heat. Lead will absorb in a pot and you will discover one more metal piece. Floating metals and pot will be call material (A).


Final Part.

Now, we are near to our final result. Wash metal piece with tap water. Take a stainless steel pot and put the metal piece in this. Dip in water and add Nitric acid again and again until reaction. If reaction goes slow down and metals lest then pour the solution in another plastic or glass pot. Repeat this procedure until all metals dissolve. Then pour the solution again carefully. Gold will not dissolve in nitric acid and settle down in powder form. When you will pour solution, you can also use filter paper.Treat gold dust with nitric acid 3 times and wash with water. If you want purity, Apply aqua regia process directly on gold dust and then melt it.

Palladium & Silver Recovery:

Now, Palladium, silver and other metals are in nitric acid solution. For silver recovery, simply add HCl or NaCl until white clouds appear. Leave it for settle down and filter it. For silver melting, you can watch the video tutorial.
For palladium precipitation, you can use one chemical from below chemicals.

  •  DMG (dimethyl glyoxime)
  • Sodium Chlorate
  •  Sodium Cyanide

I use DMG (dimethyl glyoxime) because it gives 99% purity. Simply dissolve 50-gram DMG in water for 10 kg MLCC. DMG will not dissolve completely just twist it and add to the solution. The reaction will not do immediately. Leave it for 24 hours. Palladium will precipitate like orange juice pulp and not settle down. Don’t worry and start filtration. Wash with water 4 to 7 times palladium pulp carefully. If you will not watch properly, this will effect on the purity of palladium. Let dry palladium powder and then melt it. Palladium melting is some difficulty. Palladium can melt only with an electric furnace, Oxy hydrogen flame or oxygen torch.
