Step 3 Prepare Electronics for Gold Extraction. In this step, you will need to take your electronics device and pull out any PCBs from it. On the PCBs, look for gold color. When you find gold, strip all components off the PCB. If necessary, break the PCB in order to fit it into beaker. In order to extract gold from electronic waste, first, unwanted elements must be removed from the combination. Thus, copper, silver, and selenium were omitted from waste sludge using hydrometeorology method (acidic leaching). In this research, as the aim is analyzing the extraction of gold, to achieve the waste containing gold, all the three ...
