Sustainable technique recovers gold from ewaste cheaply iron and cobalt, found in printed circuit boards. Curtin University scientists have developed a gold and copper extraction process
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.
A. The amount of gold you will get from 4 tons of circuit boards may not be worth the effort and cost. There are at least two ways to get the gold (1) cut off the tabs and strip them in cyanide (2) burn the entire collection, smelt the copper and gold out of the ash, then extract the gold from the
