Melt pure silver twice or a little 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 dissolve all other metals except gold ] 3. Fold the alloy and put it into a volumetric flask or any steel flask 4. Use Nitric Acid to start the reaction between the 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 dissolved silver 9. Rinse the flask several times with water 10. Just to be sure, add nitric acid once again and leave it on the flame for a few minutes 11. After the reaction is completed, rinse the gold with water 2-3 times to eliminate the acid 12. Collect all the gold in a thin paper, then melt it in a crucible 13. Use Borax, it will help in melting 14. 24K Gold has been recovered :) ____________________________________ Please do Like, Share, and Subscribe ----------------------------------------------------------- Thank you for watching :) #goldsmithjack #goldrefining #refininggold
