Please Like it would motivate me to upload such videos Procedure to Refine Gold 1. Melt pure silver twice or more than twice the weight of the alloy 2. Make the alloy as thin as possible in the press rolling machine [ If the thickness is less then it would take less time to eliminate all other metal except gold ] 3. Fold the alloy and put it into a volumetric flask or any flask 4. Use Nitric Axid to start the reaction between alloy and the acid 5. Supply uniform and low external heat at the bottom of the flask 6. When the reaction starts it produces red smoke so wait till it produces white smoke 7. White smoke represents the end of the chemical reaction inside the flask 8. Pour all the byproducts created in the flask into a half-filled water bucket because it contains all the silver 9. Rinse the flask several times with water 10. Just to be sure add nitric acid once again and left it on the flame for few minutes 11. After the reaction is completed rinse the gold several times to eliminate acid 12. Collect all the gold in a thin paper then melt it 13. Use Borax it will help in melting 14. 24K Gold has been Recovered --------------------------------------------------------- Please do Like, Share and Subscribe --------------------------------------------------------- Join me on: Facebook:   / goldsmith.jack.7   Instagram: https://instagram.com/gold_smith_jack...
