Where do metals come from? How do they enable the energy transition? Dr Taija Torvela of the University of Leeds explores these questions in this documentary-style channel, discussing what is the role of Earth resources, particularly metals, in our world today. The videos range from describing sources and uses of individual metals and elements, to specific ore deposit types, to investigating what metals and other resources are required in the energy transition - and beyond. The short videos on this channel provide a jargon-free, accessible resource to everyone from the general public, to schools and universities: to anyone who is interested in learning about Earth resources and their crucial role in the modern society.
Thank you for another fascinating video. I spread salt on winter roads with a salt truck. Our yard alone, 30 trucks, may go through 1000 tonnes in a major storm event. Ontario, Canada.
Another great video, professor. I relate to this video on so many levels. Firstly, I live near the NOOR solar complex in Morocco, it was nice to lean more about how salt is used in CSP. And secondly, I went to visit a salt mine recently and I experienced what you experienced underground! Thanks for the amazing informative content!
You explain very scientifically and accurately, and I salute you for your scientific content. In my mine, a streak of silica, calcium carbonate, and gold can be seen in the form of stockwork on the ground surface. And usually the gold grade is above 100ppm. Please give an explanation about the formation and origin of this organization
About concentration solar generation.... Sorry, but it does not make much sense to me when a simple photovoltaic panel converts 20% of the power of the sun directly into electricity. No circuits, no towers, no high temperatures, no risks... Concentration solar is never going to be a good idea...
I'm sure my "liked" is before the 'view' because I pause the video so I can watch little bits over a couple days - I used to tape Tennis matches and just watch them at the right times over a longer time (months - I still haven't finished a Hingis Williams from 99') - you are very relaxing so it's a more valuable video than some other's I watch
My grandparents lived in Placerville, California. Placer mining for gold was a big thing in the Sierra Nevada foothills in the 19th century to the extent that some of the first environmental laws in the USA were enacted because of the massive silt runoff from the mining operations which were starting to fill in the Siusun and San Francisco Bays.
The unfortunate Dutch Afrikaner's - trying to rid themselves of the British and their commercial allies - went on their Great Trek to find autonomy and going North landed in that region with Witwatersrand - of course that meant Diamonds and Gold which meant the Dutch would never be free - as is the case today - $$$ does not equal freedom
Thank you thank you for being you. It is so enjoyable to hear your balance of all that lays before our feet. Laughter makes us live longer and humour in all cases. Regards Alan down under very much and admire.
Thank you. I love your videos - they make so much sense of something that's always been a bit opaque to me. I didnt even know how to pronounce 'placer' until now!
I think your great and have a beautiful mind. Good work. I appreciate your passion. These minerials are the base of life and much more. You are doing a good job.Much appreciated.
Great video - I worked in Papua New Guinea in 1971 looking for porphyry deposits ... wish I had your video then ! Wandering around in the jungle not quiet sure what I was lookng for !
*They can now mine 30,000 tons per year of Nickle, Cobalt and Nickle from nodules on the ocean floor over 15,000 feet deep and the environmentalists are having a HEART ATTACK! Again! A good law would be to ban all of these protestors from owning a cell phone, computer and electric car so they will not end up being hypocrites for buying these metals.* What does a hypocrite mean? 1. : A person whose actions contradict their stated beliefs or feelings.
The point is that we have plenty of reserves on land, there is no need for deep sea mining which is probably environmentally much more harmful and difficult/impossible to regulate, than modern responsibly conducted mining on land.
And you have zero proof that is it not. Nobody knows what the real impact would be compared to responsible onshore mining, although I would be very surprised if responsible onshore mining would not have a much smaller impact. Either way, we should not do deep sea mining unless we know the full picture and can ascertain it is not more harmful.
Eventually we're going to have to recover most elements from things like sea water and waste products where they might be in very low parts per billion concentration, how do you sort out elements when you get to that situation?
