How to get precious metals out of computers?

Sharing is caring!

There is some gold in most computer chips, especially older CPUs. Locate and remove any chips that can be removed, including CPU chips and chips that are soldered onto the boards. These can usually be removed by running a flat-blade screwdriver along the legs or by clipping the legs with cutting pliers.

Can you get gold out of computers? 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.

Is scrapping gold from computers worth it? The boards from 100 computers could yield as much as $3,000 worth of gold. And you might be able to get older computers for free, just by offering to haul them away. The circuit boards found inside a single newer laptop can contain gold worth between $15.00 and $25.00.

What is the easiest way to get gold out of electronics? In another container, mix two parts hydrochloric acid and one part weak hydrogen peroxide (a concentration of three per cent). Pour this mixture over the circuit boards so they are completely submerged. Wait for a week, giving the vessel a stir every day with a glass or plastic rod.

How do you get the gold out of computer boards? Pour the concentrated nitric acid into the glass container with the circuit boards. As you put the acid in, burning fumes will start to come out of the container, so make sure you’re wearing protective gear. Stir the mixture using a glass rod until the contents become fluid in form.

What karat gold is used in computers? The karat weight of gold used in computers usually ranges from 10-24 karats. The most common karat weight for computer parts is 18 karat, which is about 75% pure gold. 24 karat gold is 100% pure gold, but it is too soft to be used in most computer parts.

What electronic has the most gold?

Computer CPU’s (processors) have the most precious metal value by weight, followed by Memory (RAM) &amp, Circuit Board Fingers / Connectors / Pins, then Circuit Boards (Motherboards), then cables / wires, with hard drives &amp, whole computers being last.

How much is a scrap computer worth?

Some reports suggest that an older laptop may contain $30 worth of gold, while newer units would include gold worth $15 to $25.

Is it profitable to extract gold from electronics?

If you intend to conduct large-scale gold recovery from electronics, then yes, it is worth it. However, if it is a small-scale gold recovery, then you’ll get meager profits. The process of physically disassembling gold from electronics and extracting gold isn’t a walk in the park.

Yet they too contain printed circuit boards that contain precious gold that is worth extracting.

Can you melt gold off electronics?

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.

What chemicals do I need to extract gold from electronics?

Precious metals like gold are inert and do not react to a single acid solution. A combination of hydrochloric and nitric acid will dissolve the gold for recovery, however, the process releases toxic fumes dangerous to humans.
