Recovering Mercury and Gold with a Shaker Table from Tailings Sudan, Africa

Mercury isn't dangerous in this form unless you're picking it up and eating it.

[@lonjohnson5161]

@@genli5603 I've been working in laboratories for decades and I'm always cautious around mercury. Eating elemental mercury is surprisingly not as dangerous as one may expect. Evidence for this is in the dental use of mercury. Mercury is most dangerous when it can get into your blood. Inhaling mercury fumes is scary dangerous and some molecular forms of mercury make for poisons that are so dangerous that one drop on the outside of a glove will kill you, but not fast, so you can spend days or weeks savoring your misery.

[@koltoncrane3099]

Dion you’re right cattle do produce methane. But did you know humans produce tons of methane, too? They fart and release pollution. Pretty soon there will be billions more people really polluting the environment making cattle not a big deal. Also, when humans throw food and other things away methane is released in dumps. I always think it’s hilarious environmentalists bring up cows and methane, but never mention that humans produce a huge amount of methane as well. Clothing is a huge user of fossil fuels. I’d love to see the day when fitness enthusiasts that love the environment advocate for banning leggings. Cause really a lot of clothes are single it’s sad.

Based on your video you could say that tailings are not tailings until you remove the values that turns them truly into tailings.

What would be your estimated tons that are classified as mineable tailings at the site you videoed removing mercury and gold?

Ask jeff Williams youtuber did a video showing a retort. You heat the amalgam on one end and the mercury vaporizies and deco senses in water leave the gold separate.

Due to the mercury content they probably have a life expectancy of onlr 35 to 40y, not a nice way to go.

[@Metal_Master_YT]

no, I recommend researching this subject, Mercury in its metallic form can't readily absorb into the body. This means they have not been exposed to any dangerous amount.

[@dalethomasdewitt]

@@Metal_Master_YT let's consider Hg vapor. More reactive though less dense. Drinking Hg is much more safe than breathing. With a good breeze you're probably safe.

[@Metal_Master_YT]

@@dalethomasdewitt well, considering they are outside, I'm pretty sure they would have a good breeze every now and again. besides, being outside is the best natural ventilation. also, check out mercury's boiling point and low vapor pressure, it makes very little vapor to begin with, thousands of times less than water.

[@kenharty6016]

That centrifuge doesnt look like its a very effecient way to do that. The ripples are all full of mud. What do you think? To me theres a whole lot wrong with that system.

[@CodockDraconin]

[@thomasfrye8996]

Agreed

[@romanchomenko2912]

If the tailings dry use retorts to evaporate the mercury and not using the shaker I do not know how Sudan is but they produce petroleum or use a solar furnace I look at the video.

[@luke-zc7yi]

wouldn't the mercury have dissolved gold in it?

[@Metal_Master_YT]

no, not very much, the solubility of gold in mercury at room temperature is very low, (this means not very much can dissolve) because of this, when he filters the mercury, almost all of the gold comes out. (but yes a small amount will not be recovered) just understand that it doesn't matter very much if it is not recovered, because the dissolved gold prevents other gold from getting dissolved, instead it just mixes and sticks to the gold, not actually dissolving. This means that future gold will be recoverable since its not getting dissolved.

[@lj7862]

Rubber gloves?

[@lonjohnson5161]

PPE is a good idea, but never assume that any specific protection will be adequate for all hazards. There is a molecular form of mercury that can penetrate rubber gloves and skin to kill you very slowly. I recommend doing a little research before choosing your PPE; even so, your point is a good one.

[@Metal_Master_YT]

@@lonjohnson5161 yeah but that's elemental mercury they're using. so it doesn't matter if a different mercury compound can penetrate gloves, since that's not the one they're using. (Mercury is not reactive enough to produce those compounds in the environment they are in) (at least, not in any significant amount)

[@Pro_Vs_Con]

Yea.... Mercury is notoriously toxic. Since it IS a liquid it evaporates at room temp and if breathed it's very toxic. It can also seep into your skin if you hold it long enough or have a cut. It does irreversible damage, and once it is in the body it ends up in your kidneys and brain, if it was not already expelled through urinating or defecating... And it will never leave your body.

[@kenalbertpinas2242]

Very bad gold cleaning using mercury. Then flowing loose on the river.

[@delfinjrbuaeg262]

They should learn the method or process of recovering gold without using mercury its more faster and enjoyable just using a Pan

[@DanielHay]

You can absorb some mercury through skin contact, but not much, and generally not enough to be a problem. It is mercury vapor that is so toxic and if they were handling it like this in an enclosed room they would certainly be having problems. If they heat it they would increase the problems for health. However, since these men are apparently handling mercury regularly they are at increased risk of skin absorption. Stepping back when the nitric is added probably isn't enough distance. If you can smell it you have probably inhaled mercury vapor too. I don't know if mercury affects sperm, but pregnant women and children should not be living in or around mercury vapor.

[@Metal_Master_YT]

You mention all these hazards, except they aren't doing many of them. they aren't in an enclosed area, they are outside, everybody I see in the video is not a pregnant women or child, they aren't heating the mercury either. if it wasn't for the nitric acid I think they would have been fine. if they step back from the nitric acid, its probably adequate. Mercury does not absorb through the skin very well, in fact, its so slow that you could touch it for hours, even days and you would be fine, these people have water and dirt on their hands, the mercury will have a heck of a hard time absorbing through both the water, dirt, dead skin and then the living skin, much less make it all the way to the internal organs. the water covers the mercury, suppressing the vapors almost entirely. not to mention mercury makes almost no vapors in the first place. and you cant smell mercury metal vapor, its odorless. the only real thing worrying me here is the nitric acid.
