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. Since I have a week I will move on to processing my solid low grade gold parts. Add Tip
For now, let’s use the salt and vinegar method. To get started, add the sea salt into a beaker, pour the vinegar in, and stir until the salt dissolves. Vinegar and salt form a powerful, but non-corrosive stripping solution needed to etch out the tiny gold particles on the computer parts.

How much gold is there in old circuit boards
We’ve sorted my list by approximate gold grade, highest to lowest; Also listed are specific examples in fewer of each category, derived from elements with the highest expected gold content. 2000 circuit boards for mobile computers or 200 absolute laptops contain approximately five troy ounces of gold.
How do you recover gold from circuit boards at home
Clear the boards
In another bowl, mix two parts bulk hydrochloric acid and one part mild hydrogen bleach (3% strength). Pour this mixture over the printed circuit boards so that they are completely submerged in water. Wait a week and stir the vessel daily with any glass or plastic rod.

Why is a series resonant circuit called an acceptor circuit & parallel resonant circuit is called Rejecter circuit
Because the model’s resonant circuit only operates at its resonant frequency, this type of circuit is commonly referred to as an acceptor circuit because at resonance, your circuit’s impedance will just as easily accept a current equal to its resonant frequency. .
Why the series resonance circuit is called an acceptor circuit and the parallel resonance circuit is called Rejector circuit
Himanshu replied. The world called series resonance is an acceptor circuit because when an applied voltage is coupled to a large number of frequencies, the circuit must only accept maximum current for the resonant frequency and reject all other kinds of frequencies in all cases.
How do you recover gold from circuit boards
Get protective equipment. Buy concentrated nitric acid. Place your company’s printed circuit boards in a glass container. Pour concentrated nitric acid directly into a glass container with regular pellets. Drain the nitric acid from the acidic mixture solution.
How do you recover gold plating without chemicals
So how do you remove precious metal from a computer without partial chemicals? Use white vinegar, sea salt, and hydrogen peroxide to salvage gold foil from your computer board fingers. Then bleached to dissolve and precipitate vitamin C.
