The researchers extracted the metal parts from 20 old computer motherboards and dissolved them in an acid bath to ionize the metals or separate them into positive and negative ions.
a white sediment instead of the expected brown precipitate when attempting to extract gold from computer parts, there could be a few potential reasons: 1. Incomplete dissolution of gold. The acids used (like aqua regia) may not have fully dissolved and brought all the gold into solution before precipitation. Ensuring complete dissolution is key.
- In this video, the content creator demonstrates the process of recovering gold from printed circuit boards (PCBs) found in scrap computer parts. - The process involves three major steps: separating the gold from the circuit boards, purifying the gold, and precipitating the gold from a solution. -
Extracting gold from computer parts at home can be tricky, but it is possible with the right tools and knowledge. First, you will need to gather all the computer parts containing …
Extracting gold from computer parts takes time and involves hazardous chemicals like cyanide. But with the right skills and precautions, the payoffs can be worthwhile: Desktop computer recycling can yield 0.2-1 gram of gold per part, worth over $20.
The acid will gradually darken, and the gold will separate from the scraps, floating on the surface. Pour the mixture using the filter and another glass container. The gold flakes will stay in the filter. Wash the gold flakes with methanol, then with water to remove any residue. Procedure number 3: using fire. Break the circuit board into small ...
