Scientists have developed a new key-hole surgery technique to extract metals from the earth - which could revolutionise the future of metal mining
A team of international researchers, including Dr Rich Crane from the Camborne School of Mines, University of Exeter, have developed a new method to extract metals, such as copper, from their parent ore body.
The research team have provided a proof of concept for the application of an electric field to control the movement of an acid within a low permeability copper-bearing ore deposit to selectively dissolve and recover the metal in situ.
This is in contrast to the conventional approach for the mining of such deposits where the material must be physically excavated, which requires removal of both overburden and any impurities within the ore (known as gangue material).

No more digging – a new environmentally friendly way of mining
Researchers from The University of Western Australia, Australia’s national science agency CSIRO, the Technical University of Denmark and the University of Exeter have developed a new mining technique that uses electric fields to extract metals from hard rock ore.
The technique could replace the traditional method of digging which results in significant costs to the environment.
Digging methods are currently used in 99 per cent of mining activity, often resulting in significant environmental degradation and huge quantities of solid waste.
Global estimates of waste are of the order of 100 gigatonnes per year, significantly larger than any other form of waste generated by humans.

“You need to show that you’re human”
Henrik Bechmann was named Lecturer of the Year 2021 for his extraordinary ability to teach varied and exciting classes and for his willingness to go far beyond the call of duty to help his students. He himself believes that personal relationships are of the essence.
“Why me? There are so many competent lecturers at DTU.”
Henrik Bechmann is mildly surprised at having been named Lecturer of the Year 2021. It’s unfair to all the others, he finds. But he is then reminded of a story about a golfer who, after he has sunk a putt, gets the following comment from a reporter: “What a lucky shot”, to which he drily observes: “I’ve learned that the more I play, the luckier I get”.

Pea sized stones heated to 600?C in large, insulated steel tanks are at the heart of a new innovation project aiming to make a breakthrough in the storage of intermittent wind and solar electricity.
The technology, which stores electrical energy as heat in stones, is called GridScale, and could become a cheap and efficient alternative to storing power from solar and wind in lithium-based batteries. While lithium batteries are only cost-effective for the supply of energy for short periods of up to four hours, a GridScale electricity storage system will cost effectively support electricity supply for longer periods - up to about a week.
