Do not Throw Them Away: Old Devices Might Comprise 22-Karat Gold

You have almost definitely thrown it away with out giving it a lot thought.

Old motherboards, worn-out computer systems, and out of date digital devices typically find yourself within the trash – however what if we advised you that you’re really discarding a possible goldmine?

Literally.

The Method

Researchers from ETH Zurich have developed a way to extract gold from digital waste in a method that’s so sustainable that even probably the most ardent environmentalists would applaud.

And probably the most shocking a part of all of it? The secret lies in one thing as harmless as cheese.

This is in line with Huffington Post.

The course of makes use of a byproduct of cheese manufacturing, which has an virtually magical capability to extract valuable metals from waste.

First, metallic components from previous motherboards are dissolved, ionizing the metals. Then, the byproduct binds to the gold ions and extracts them from the answer.

When the substance is heated, the collected gold particles are launched, that are then melted collectively right into a 22-karat gold nugget.

Experiments Showed Promising Results

In an experiment, researchers efficiently extracted a 450-milligram gold nugget from simply 20 previous motherboards.

The nugget consisted of 91 p.c gold and 9 p.c copper and was valued at 33 {dollars} (roughly 237 Danish kroner, ed.).

This could not sound like a lot, however contemplating the huge portions of digital waste produced globally, the potential is gigantic.

So, the following time you take into account throwing out your previous laptop, suppose once more. Perhaps it’s not simply trash, however a small treasure ready to be “unearthed.”
