The Royal Mint to construct plant that may extract gold from e-waste

LONDON — Britain’s Royal Mint plans to construct a facility that may extract gold from digital waste, with the plant set to be absolutely up and operating in 2023.

In an announcement Monday, the government-owned firm which manufactures valuable metallic merchandise and cash mentioned it could use what it referred to as “patented new chemistry” from a Canada-based agency referred to as Excir to get better gold from the circuit boards of cell telephones and laptops.

In accordance with The Royal Mint, the method is ready to get better “over 99% of the valuable metals contained inside digital waste — selectively focusing on the metallic in seconds.”

The restoration, it mentioned, takes place at room temperature, versus the excessive temperatures required for smelters to course of e-waste. The plant shall be situated in South Wales, U.Ok., the place the mint relies, with building starting this month.

It mentioned it anticipated the power to course of as a lot as 90 metric tons of circuit boards sourced from the U.Ok. every week. This could produce “tons of of kilograms” of gold yearly, it added.

This week’s assertion builds on a earlier announcement from Oct. 2021 by which The Royal Mint mentioned it had signed an settlement with Excir to roll out its know-how within the U.Ok. In that launch, the Mint mentioned the method may probably additionally get better copper, silver and palladium.

The widespread proliferation of know-how akin to good telephones, tablets and laptops has seen digital waste change into a subject of a lot debate and dialogue lately.

In 2019, the world produced round 53.6 million metric tons of e-waste, in response to the World E-waste Monitor 2020 report. The report additionally mentioned simply 17.4% of this waste was “formally documented as correctly collected and recycled.”

Along with this low assortment and recycling fee, the report additionally mentioned e-waste contained dangerous substances together with mercury, hydrochlorofluorocarbons, chlorofluorocarbons and brominated flame retardants.

As considerations concerning the setting and sustainability mount, firms like Excir wish to roll out and monetize strategies centered on the recycling and repurposing of e-waste.

Others embrace New Zealand-based Mint Innovation. In 2020, Ollie Crush, the corporate’s chief scientific officer, told CNBC it had “developed a biological process for recovering valuable metals from bizarre feedstocks, akin to digital waste.”

Crush defined that Mint Innovation’s system concerned taking scrap materials and “grinding it up right into a sand like consistency.” 

“The rationale we do that is that we have to be sure that we’re exposing all of the metallic contained inside to a subsequent chemical leaching course of,” he added.

“As an example, whenever you have a look at circuit boards, they have numerous chips on them — a variety of the worth is contained inside these chips, so we actually want to verify it is uncovered.”
