Gold from sea water (new technique)

Aug 07, The concentration of gold in seawater is about 13 ug/m^3 (not 13 mg), so to extract one troy oz of gold you would have to process about 23 million M^3 of seawater If the device could average 10 liters/second it would do that in about 7 yearsOnly one gold extraction method cannot be used to recover gold from all parts of computer Nitric process or CN process can be used to remove gold from gold plated/polished pins and connectors From CPUs we can recover gold through aqua regia.
