If you’re hoarding old electronics like us, there’s a good probability you have a decent amount of gold sitting around in cardboard boxes and storage containers. Gold melts at 1064 ˚C, much hotter than what can be obtained by a simple propane torch.

1,064 °C

Instead of nitrate as an oxidizer, you’re using hydrogen peroxide, which is also a powerful oxidizer. The hydrogen peroxide oxidizes the gold and the chloride ions form soluble complexes. Also happening is the dissolution of oxygen into the acid, which helps dissolve gold.

Yes, Its profitable to recycle gold from electronic devices because it makes your outdated electronics so valuable even after they’ve reached the end of their life cycle. As Now a days traditional mining is the best way to get at the precious materials needed for electronics production.

There are two standard methods for extracting gold from electronic scraps: burning off the gold using high temperatures, which is energy intensive, expensive, and releases toxic gases.

In addition to gold, other metals like lead and copper are common in electronic waste. The cathode ray tubes in older televisions and computer monitors contain lead, barium, and strontium. Copper is found along the tracks of printed circuit boards, while gold is popular in connectors due to its conductive properties.

In phones, most of the gold is in the SIM card, the main board and the smaller components on the back of the LCD screen. Use a magnet to separate all gold-plated steel parts, as you need a different process to extract it. “Older electronics have more gold in them,” says Murchison.
