Seriously? Take one guess where green-energy backers want to mine

A new report reveals that green energy advocates are thinking about ways to get the elements that are necessary for the massive expansion in the use of electric vehicles Joe Biden is demanding of Americans.

How Green Mining Paves The Way To A Sustainable And Net Zero Future

How Green Mining Paves The Way To A Sustainable And Net Zero Future
July 3, 2021

Scientists at the Earth Sciences department of the University of Oxford demonstrate how to directly extract valuable metals from hot salty fluids (brines) trapped in porous rocks at roughly 2km below dormant volcanoes. They propose that this green-mining approach will sustainably provide essential metals for a net-zero future.
Magma underneath volcanoes releases metal-rich gasses that ascend toward the surface. These gases separate into brine and steam as the pressure drops. Most of the dissolved metals in the original magmatic gas become concentrated in the dense brine, which gets trapped in porous rock. The less-dense and metal-depleted steam continues to rise to the surface, where it forms fumaroles, the gases, and steam seen at the many active volcanoes around the world.

One hurdle standing in the way of a transition to renewable energy is the increased need for mining that these technologies bring. Now, Oxford scientists are investigating a new way to mine valuable metals trapped in hot brines beneath volcanoes – with geothermal power produced as a by-product.

Oxford scientists show how green mining could pave the way to net zero and provide the metals we need for a sustainable future

Share
Scientists at the University of Oxford demonstrate how it is possible to directly extract valuable metals from hot salty fluids (‘brines’) trapped in porous rocks at depths of around 2km below dormant volcanoes.
They propose this radical green-mining approach to provide essential metals for a net zero future – copper, gold, zinc, silver and lithium – in a sustainable way.
Magma beneath volcanoes releases gases that rise towards the surface. These gases are rich in metals. As the pressure drops, the gases separate into steam and brine. Most metals dissolved in the original magmatic gas become concentrated in the dense brine, which in turn gets trapped in porous rock. The less dense, and metal-depleted steam continues up to the surface, where it can form fumaroles, such as those seen at many active volcanoes (see attached photo).
