For gold recovery from computer parts and other electronic scrap, we have to apply different recovery methods. To remove gold from gold plated fingers and connectors we can use cyanide process both chemically and electrically. If the layer of gold on the connectors is thick then the nitric process can be applied.

Then add 1-liter water. Approximately 1 to 1.5 L nitric acid will use for I kg gold plated connector pins. But add nitric acid 200 ml every time. When reaction will end then again add more nitric acid until all metals dissolve. Your solution color should be green. When all metals dissolve then leave it for cool.

The Canadian researchers' alternative is a solution of acetic acid and an oxidant — a nontoxic technique to dissolve gold, which is stripped from circuits in about 10 seconds, leaving intact copper, nickel, iron, and other metals in printed circuit boards. Dive insight: Traditional extraction costs $1,520 for one kilogram of gold.

A. The amount of gold you will get from 4 tons of circuit boards may not be worth the effort and cost.
