Maker of UK Coins Starts Turning E-waste Into Gold

The Royal Mint, maker of the UK's coins, has begun processing electronic waste to extract gold from it, the BBC reported.

The company has built a large industrial plant on its site in Llantrisant in Wales to remove the precious metal from old circuit boards, it said on Wednesday.

The gold is initially being used to craft jewelry and later it will be made into commemorative coins.

At the Royal Mint plant, piles of circuit boards are being fed into the new facility.

First, they are heated to remove their various components. Then the array of detached coils, capacitors, pins and transistors are sieved, sorted, sliced and diced as they move along a conveyor belt.

Anything with gold in it is set aside.

“What we're doing here is urban mining,” says head of sustainability Inga Doak.

“We're taking a waste product that's being produced by society and we're mining the gold from that waste product and starting to see the value in that finite resource.”

The gold-laden pieces go to an on-site chemical plant.

They’re tipped into a chemical solution which leaches the gold out into the liquid.

This is then filtered, leaving a powder behind. It looks pretty nondescript but this is actually pure gold – it just needs to be heated in a furnace to be transformed into a gleaming nugget.



Scientists Detect Longest Pair of Jets Streaming from Supermassive Black Hole

Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy.
The jets shooting hot plasma are the largest ever spotted – about as long as 140 Milky Way galaxies lined up end-to-end.
“This one has managed to reach a size that’s so big,” said Eileen Meyer, who studies black holes at University of Maryland, Baltimore County and who was not involved in the study.
The discovery, made using images from a European radio telescope, was reported Wednesday in the journal Nature, The Associated Press said.
Black holes eat most space debris that falls their way. Sometimes, heated-up plasma makes a narrow escape by spewing out in thin, high-energy jets.
The jets can break apart soon after their creation, jostled by space turbulence or starved in the absence of new matter. But jets from supermassive black holes can become supersized.
The latest combined jets from a faraway supermassive black hole are around 23 million light-years long. That’s about 7 million light-years longer than the previous recordholder. A light-year is 5.8 trillion miles.
Study co-author Martijn Oei said researchers weren’t expecting to find long black hole jets so early in the universe’s history. The jets date back to when the universe was less than half its current age.
Studying the jets could reveal whether they had an influence on how the early universe came to be, said Oei with the California Institute of Technology.
