Scrap Gold Recovery? Page 1 EEVblog
Hi Does anyone have any experience with gold recovery from scrap electronics? Things like Memmory boards, CPU pins, and gold fingers from connectors. I am wondering if recovering gold from these would be a viable option, or if it is too risky/a waste of time. Might be a nice micro business. Logged Falcon69Step 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 How to Extract Gold From Electronics Instructables

Gold Recovery from E-Waste by Porous Porphyrin–Phenazine
Gold recovery from electronic waste could prevent excessive mining with toxic extractants and provide a sustainable path for recycling precious metals. Unfortunately, no viable recycling is practiced, except burning electronic circuit boards in underdeveloped countries, mainly because of the lack of chemical scavengers as adsorbents. Here, we This study aimed to recover copper and gold from a waste printed circuit board (WPCB) using monosodium glutamate (MSG) supplemented with a clean oxidizer(s) under 30 °C, 150 rpm, and an initial pH of 7.00.
