Zinc: the quiet protector 

And it is common and cheap and makes up the core of US pennies. It replaced copper in this role when copper became more valuable in the 70's. Thank you for covering these deposition processes, and why zinc is often mined as a less valuable component in a more desirable ore.

This is awesome multiplied by 1*10^35. Thank you. In year 1976 I found a chunk of metallic ore here 36.577383,-115.675902 but I had no knowledge what the metallic is, except that some of the content is a pyrite, until I watched this video. I kept that ore up to present day: it is sitting on my desk right now. It is chalcopyrite, probably from a gravel quarry, that was transported from the mine at 35.549194,-115.277748 to be used to "pave" dirt roads. Lucy Grey mine, Sunset District, Clark Co., Nevada, USA. Of course I could be wrong: I am uneducated. I worked a turquoise mine at 35.43028,-115.95639, living at another turquoise mine at 35.426276, -115.955615. Golly, that was a miserable job.

Great series. Keep up the good work, Taija and Rob.

You are a very cool person.

Another informative video! Thank you for your dedication to this!

Well put... looking forward to seeing more 😊

Very interesting and very well done. The walk aways are a great touch. :)

Only a few seconds in and that Panoramic view behind you was instantly relaxing

"Come back, zinc!" Sorry, i'll just see myself out.

Excellent. Thank you!

Another interesting fact about zinc is that it can only be produced in supernovas. The fusion process in stars only produces elements up to iron on the periodic table. Zinc is a necessary nutrient for life. This means that if it wasn't for the phenomenon of supernovas we would not be here.

I'm sure hoping I have a lot of zinc under my land! Zinc is one of the main metals found in my mining district.

Another really informative video! But please consider boosting the audio (speech) level by a couple of dB in future videos. Cheers from Nova Scotia.

Your videos are really good. I liked the manganese video a lot. It brings me to a question/thought I have all the time. I am a fan of caver youtubers, for example "Action Adventure Twins". They are always going to different caves and bringing their camera and posting edits of the trips. One thing that I always wonder about, but have no way of knowing, is how many of the caves they visit are also some sort of mine. Sure, a cave can form naturally, but once there is a way to access an underground area, perhaps miners would scout it, and if they found a vein, exploit it (just at some point in history) ... Or ,, in some other cases, perhaps miners were exploiting a vein, and during this, they encountered a cave. Well, I know for sure this has happened, and there are some examples that are unmistakable, but there are LOTS of times when I see a video, and it LOOKS like the manganese mine, but there's no way for me to tell if it's a natural cave or a mine, and the cavers always seem to just assume it's a natural cave. Another thing I always think about, particularly here in the US, is that so many mines may have existed illegally/undocumented. I always imagine some little group of people trying to keep a small mine a secret and then dodging their taxes, in the same way that the gold rush went down. I suppose someone very familiar with all of the ways a historic mine could look might be able to just see which passages are which , but I often can't help but imagine that perhaps some of the more "natural" passage are actually also some exploitation or some impact from exploitation. An example of this wondering is some of the flowstone,,, could it have been possible that use of chemicals to isolate minerals from ores and then the unregulated dumping of those acids/chemicals might have caused more rapid dissolving of rocks below the dumping grounds,, resulting in flowstone formations that could then be identified as this??

I zinc this was a great video

I have a friend who specializes in sphalerite in his mineral collection. It is a very boring and drab mineral in my opinion. Then again, he has little competition and can always get the best deals at the shows. In my line of work, a lot of ground water contamination is caused by leaking underground steel tanks containing gasoline. This can be prevented by attaching sacrificial zinc anodes to minimize the corrosion of the steel tanks. Unfortunately, the anodes need to be checked every few years, and a lot of station owners fail to do this.

بسیار متشکرم پرفسور از مطالب شما که بسیار اموزنده هست لذت میبرم. لطف فرمایید در مورد چگونگی تشکیل ناگت طلا توضیح فرمایید. متشکرم

Is zinc necessity in our body?

Copper produces Electricity But you said wind turbines need zinc for what ?
