- @MakeGold Here are the steps to melt scrap gold into a gold bar
Materials Needed
Scrap gold
graphite crucible
Flux (borax or a commercial flux)
Tongs or heat-resistant gloves
Heat source (propane gas torch or furnace capable of reaching gold's melting point of 1,948°F/1,064°C)
Steps
Sort and clean the scrap gold thoroughly to remove any non-metallic items like plastic or stones.
Place the clean scrap gold pieces into the crucible. Add a small amount of flux, which will help collect oxide impurities that rise to the top as slag.
Maintain temperature just above the melting point.
Once fully melted, skim off any flux slag or oxidized impurities from the top with heat-resistant tongs.
Allow it to cool completely before handling.
Safety Notes
Use proper ventilation as gold releases fumes when melted.
Wear heat-resistant gloves and eye protection.
Have a fire extinguisher suitable for metal fires nearby.

Be extremely cautious when working with acids and high heat. Use proper safety equipment like goggles and gloves. Consider having scrap professionally refined if inexperienced. The amount of actual gold recovered may be small depending on the components used.
If you use a Tungstène crucible and induction heater the result will be more clean and even and no borax needed too , what do you think ?
@@user-eq9xq8km1l Thank you for the good advice. Overall, using a tungsten crucible and induction heating can be an efficient and relatively clean method for extracting and concentrating the gold from electronic waste, especially when dealing with larger volumes. However, it does involve higher capital and operating costs compared to chemical extraction methods. A thorough cost-benefit analysis would be recommended to assess its viability for a specific scale of operation. Proper safety measures, including protective equipment and ventilation, are still essential when handling molten metals.
Exactly how i do it! With my simple propane torch... a standard melt and pour do not work. I have to melt them in my graphite molds.
