we are excited to post this video and show you all our progress on processing printed circuit boards pcb's for gold, copper and other metals with our hammer mill and shaker table. we have the
extracting gold from a printed circuit board is definitely possible but the amount of the gold in the pcb has to be evaluated first. the process involves a number of steps which have to be carried out carefully in order to get the desired results. there are some instruments and acids involved in the process. necessary precautions must be taken before starting the procedure.
another good mechanical way would be to use a dedicated pcb guillotine. either way, the goal is to cut the fingers as close as possible to the edge of the gold plating. the usual gold plating thickness on fingers is appx. 30 microinches 0.762 micron , though it is not that uncommon to find thinner plating on cheaper chinese made electronics.
metal extraction processes for electronic waste and existing industrial routes: a review and australian perspective gold and silver into base metals bms copper, lead pcbs and in measuring equipment and discharge lamps . it is also used in medical equipment, data transmission, telecommunication, and
how to recover silver and gold from computer parts, e-waste, chips, cpu, x-ray films, photographic waste, aqua regia, cyanide solution, circuit boards and rams. recovery methods extract or recycle of precious metal like palladium, silver and gold.
compounds. pcbs contain high amounts of precious metals; about 20 wt% copper, 0.04 wt% gold, 0.15 wt% silver, and 0.01 wt% palladium. the extraction of these metals from pcbs is both profitable and environmentally worthwhile. hence, this study aims to design a commercial process to extract these four metals from pcbs of computers and mobile phones.
