Do circuit boards have real gold?
Ever noticed those shiny gold-colored parts on the circuit boards? Those bright pieces of metal are, in fact, gold. Gold is used on electronic circuit boards because of its excellent conductive properties and because it doesn’t corrode or rust over time.
How do you remove gold from circuit boards?
Put the gold fingers and clean circuit boards in the coffee pot, in another container mix two parts muriatic acid and one part hydrogen peroxide and add to the coffee pot until it just covers the gold fingers and wait a week giving it a stir daily.
What electronic has the most gold?

Which electronics have the most gold in them?
Is it worth extracting gold from computers?
When done at a large scale, recycling computer and laptops for gold and silver can be very profitable, especially when you are paying next to nothing for the e-waste ore. Mining circuit boards for gold can be more valuable than mining much of the highest grade gold mine ores.
What electronics have the most gold in them?
Short Answer: Computers and televisions typically have the most gold of any household electronics. Cameras, radios, and media players – especially older models – also contain gold in their circuit boards. Other electronics like game consoles, tablets, and phones only contain trace amounts of gold.

Pour the concentrated nitric acid into the glass container with the circuit boards. Stir the mixture using a glass rod until the contents become fluid in form. Drain the nitric acid from the mixture.
What is gold in circuit board?
Gold in these circuits occurs as a layer over a base metal substrate such as nickel or copper. Separate the gold-plated metal parts in the circuit boards using a magnet. Some gold-plated parts may be inside ceramic components.
