Cell phone Sim cards recycling can give you a handsome profit. In these days, a big quantity of sim cards converts to scrap. In this tutorial, I will tell you an easy method of sim cards recycling. But first, hit that like button to show your support.


Let’s start our recycling. Put sim cards in a pot like a beaker or plastic bucket. Now start adding hydrochloric acid until sim cards dip. Add 5 percent water quantity of hydrochloric acid. If you don’t know about hydrochloric acid then read beginners guide tutorial.

Now, add a small amount of nitric acid and leave it for reaction. When reaction end then add nitric acid until all gold plating part dissolved in solution.  When you see that all gold plated part has dissolved then stop adding nitric acid and leave it to cool down.

Now, it’s time for filter the solution. You can use a fabric or filter paper for this. Wash sim cards with water 2 or 3 time. Now start adding urea until reaction. Urea will neutralize the nitric acid. In the video, I did not use urea because my sim cards quantity was small and I added a large amount of water in gold solution. After adding urea, give a twist the solution.

Add SMB to the solution to make SMB solution. You should take SMB double quantity of gold accept ratio. For example, if your idea is gold in solution 4 gram then take 8-gram SMB and make a solution. Add SMB solution to gold solution and add water until solution volume become double. Leave it overnight.

Next day, you will see. All gold dust has settled down. Filter gold dust with filter paper and melt it. If you want to know about gold melting then you should read my gold melting tutorial.
