Manganese, the hidden giant

Manganese is the most consumed metal in the world after iron and aluminium, but most of its uses are hidden from view so its importance for our society is not necessarily very obvious. Over 90% of the manganese used annually goes into metallurgical applications, primarily steelmaking - in fact, you can’t make steel without manganese. But manganese is set to become even more important as we move away from fossil fuels. New battery technologies in development that rely on manganese may revolutionize electric vehicle production; in addition, pretty much all low-carbon energy infrastructure requires vast amounts of steel and, therefore, manganese. Dr Taija Torvela explores where and how manganese deposits form.

Manganese is also used as the major alloying element for making aluminum sheets.The most common use that the public experiences is the humble aluminum beverage can. Just the main body of the can (alloy 3004), but not the lid (which uses magnesium rather than manganese). Being medium strength, aluminum-manganese alloy sheets are typically in general sheet metal work.

While cleaning up a petroleum pipeline spill, I saw a fascinating Eh effect at a small emergent spring in a deep arroyo at the downgradient limit of the subsurface contamination. Initially the spring ran clear with a thin petroleum sheen. After a few months, the spring’s sediment turned orange from oxidizing iron mobilized from the subsurface by indigenous aerobic bacteria consuming the petroleum and oxygen in the ground water. A week later the sediment turned black from oxidizing manganese, as the Eh in the sandstone formation continued to drop. Lastly, another week passed and the sediment turned grey from oxidizing sulfur. It was fascinating to observe.

@ecoislands1540 3 месяца назад

thank you @jaymacpherson8167 ! Did you get a sense of the flows or have a chance to check the pH shift as the system changed? Might the petro/cbod have been enough to go through all of the iron, then, Mn, then sulfur in the contacted pores (like heap leach), such that that the discrete hydrogeologics might be stripped of those elements (in that small area?). Thanks!

Minerals precipitating in rings around bodies of water, it all makes sense. I've seen it before around thermal springs in Yellowstone but had never thought of it happening in large scale (pardon the pun). Thanks for the enlightenment!

Right off the bat that is amazing to me - the 3rd most consumed metal - and yeah - I don't even think of it - I just scrapped maybe 1500 pounds of steel and aluminum today (cleaning out years of gears sprockets - auto parts etc ) and I suppose there was Manganese in all that or it was used to make it - I'll have to watch more to find out

@thorwaldjohanson2526 4 месяца назад

I'm much more familiar with high performance alloys for tools and aerospace, where manganese is usually a smaller component, and other elements such as nickel, chromium and vanadium are more important. Learning that manganese is the 3rd most used metal was news to me. Always happy to learn something new :). Btw, some small constructive feedback: the audio sounds very compressed (aggressive noise filtering) when outside. I loved the content, but you might want to invest in a lav mic. That would significantly improve the quality of the content without much cost.

Got interested in geology by watching a few gold seeker channels, mainly Jeff Williams. Have no desire to search for gold but became interested in the academic part of it. This dovetails right in. I don’t understand it yet, or have a big picture view in general, but have researched some of the nomenclature ive heard and am putting it together.

My functional swords also have manganese for added integrity. Didn't know it was used in batteries, too

@CH-pt8fz 4 месяца назад

Glad your channel popped up on my feed. Very interesting. We use manganese on wear plates and paddles for airless shot blasting machines and abrasive environments as it work hardens and it then actually slows dow the effects of the abrasives on the plates giving longer service schedules on the machine one draw back is, it dose become brittle so they can shatter if they receive heavier impacts than designed for. Im afraid i cant tell you the percentage of manganese in the alloy, we just refer to them as manganese plates or paddles but they're cast not machined because they work harden so fast.

@nathanguyon7620 3 месяца назад

Nice video, near subject matter. No idea why the algorithm showed it to me, but it works-- actually been scratching around for a couple of manganese minerals. Have a property in Alleghany county NC, where Alleghanite and Galaxite (even though Galax is in another county, it was first described in Alleghany) were first described. I REALLY want to find my own nice samples of both : )

Manganese phosphate is an interesting permanent violet pigment. Quite highly metameric. Hue shifts to a redder violet in most artificial lighting. More a Bluish Violet in 'Natural light. Manganese blue is a now v.rare artist's blue tending to a greenish cyan. More striking I think than near equivalent Pthalocyanine tints.

@stefkuna 4 месяца назад

Great video, thanks! Can manganese easily be recovered in recycling? Or perhaps in reusing scrap steel it just stays where it is and is reused.

@ourmetallicearth 4 месяца назад

I'm not sure about the details but I do think it is reasonably easy to recycle manganese from steel, after all over half of manganese in scrap metal is recycled globally.

You might visit a scrap yard sometime to 'close the loop' on OUR METALLIC EARTH - the guys there would love to have a visit from a smarty pants like you (they are mostly see grizzled older guys but there are occasional scrap women as well) - it is amazing the stuff you see there - sort of sad at all the creative energy lost and I always say we should pray to a "God of the Furnace" or else we would suffocate pretty quick in all this stuff we create literal mountains of metal scrap ready to enjoin virginal metals coming from pure earth to produce more unnecessary necessary 'stuff'

@jackprier7727 4 месяца назад

Uses hidden, I guess! I had zero idea manganese was used so widely and heavily. More than copper?

@ourmetallicearth 4 месяца назад

Copper is pretty close in terms of amount mined annually so it's debatable which one is "bigger" in fact. It's hard to get reliable metrics because most stats for manganese are calculated for Mn ore, rather than the pure metal, whilst for copper they are for the pure metal. But Mn ore contains about 35% manganese metal, and we mine about 50-60 million tonnes annually so that's about 20 Mt pure Mn, about the same as the annual copper mining. But none of that takes into account recycling, another 10 Mt recycled copper is used annually so that our total Cu consumption is about 30 Mt per year; but I haven't been able to find out how much recycled Mn we use annually (I know that >50% of Mn in scrap metal is recycled, but I don't know what that amounts to in terms of Mt manganese).

@TotalFreedomTTT-pk9st 4 месяца назад

@@ourmetallicearth Yep - I've got quite a bit of copper wires and a quite a bit of stripped down aluminum ready to go to the scrap yard - but no barrel for manganese as of yet since I'd have no clue what it is

Wow - pretty steep Ore price per ton from 2015 to 2017 - $2 to $10 - what caused that ? pretty volatile price change for some reason

@ourmetallicearth 4 месяца назад

Not 100% sure but I think it was due to a combination of higher demand from industry, particularly in China and a period of reduced mine production in South Africa.

Thank you for the useful and helpful content. Doctor, please prepare a clip of the formation of gold from leached pyrite. Because the source of the gold deposits that I discover is leached pyrites. And are these pyrite leaches seen in the form of gold nuggets? And why mercury is involved in most of these leaches. Thank you very much

@ourmetallicearth 4 месяца назад

I'll do a video on gold at some point but my videos are not aimed at specialists so I doubt I will talk about gold remobilisation from pyrite. But have a look at the papers by Hastie et al. on the subject.

Does anyone in the comment section know what the temperature gradient is per 100 feet going down into the Earth - I mean last year when it was 0 degrees F outside but the basement floor was roughly 40 degrees - which impressed me and then we know that something 'molten' is going on at some depth below - but I have never seen a 'gradient' curve for what point the temp is like 420 degrees or 68 degrees - and is it linear or non linear and at what point does the heat energy (via compression ?) start to reflect back up ?

Are we willing to fu up the planet to make a bunch of EV for a few privileged?, mining has to know when to stop, you can't pollute groundwater refining gold with cyanide for you to put a useless ring on your finger...I don't care if it's profitable this has to stop, is pure nonsense...extract what, where, at what cost, to make what for whom?, why this fundamental reasoning is completely absent in the video and in the general industry?, peoples minds and life styles have to change drastically...
