Let me tell you about gold, oh, that shiny precious thing folks dig up from the ground. You might’ve heard of some fancy ways they do it these days, but lemme tell you about the old way, the “amalgamation” process. That’s how folks in small places, where there ain’t big machines or high-tech tools, get gold outta dirt. Sounds simple, but it’s a real job, I tell ya!
So, what’s this “amalgamation” about? Well, that’s just a big word for mixing gold with mercury to get it outta the dirt. You see, gold and mercury go together like peas in a pod. When folks got a pan of dirt with little specks of gold in it, they add mercury to it, and guess what? That gold just sticks right to the mercury. Easy as that!
Now, how they do it might sound strange, but listen close. First, they go down to the riverbed or wherever the gold is. They take some of that dirt and gravel that’s got little bits of gold, and they give it a good wash. This is where you get what they call “gold-bearing sediment” or concentrate. Fancy words, but really, it’s just a pan with the best bits left after washing.
Next step? Add the mercury. They don’t need a whole lot, just enough to cover them gold bits. Now, the funny thing about mercury is, it loves to stick to gold. Once they’re mixed, you end up with what they call an “amalgam.” That’s gold and mercury mashed up together. This part’s like making a sticky ball, gathering all that gold together nice and neat.
But they ain’t done yet! After they’ve got this gold-mercury mix, they gotta scrape it off and do one last thing to get just the gold. They heat it. Yep, they use fire to burn off the mercury. That mercury turns to smoke, and it floats away (now, mind you, that ain’t the safest thing for the air, but folks been doing it this way a long time). What’s left? Just pure, shiny gold!
Why folks use this method? Well, it’s simple. You don’t need big machines, don’t need no lab. Just some mercury and a bit of fire. Small miners, like the ones digging here and there in the hills or by the river, they like it ’cause it’s cheap and it works. No fancy tools needed!
But, is there a downside? You bet there is! All that mercury smoke going up, well, it can get into the air and into people’s lungs. They breathe it in, and over time, it can make folks real sick. Some people also dump that mercury back in the water when they’re done, and that ain’t good for fish or anything else drinking that water. So, even though it works, it comes with a price, and people are looking for safer ways these days.
Amalgamation and the small-scale miners
In places where folks still work on a small scale, with just their hands and maybe a few old tools, they stick with this old way. This whole “amalgamation” method might sound like it belongs in history books, but there are plenty of places still using it. They’re in it for the gold, same as anyone else, but they just don’t have big companies backing them up.
- First step: get the dirt or sediment with some gold in it.
- Wash it up till you got a pan of concentrate.
- Mix in some mercury till the gold sticks right to it.
- Scrape off the gold-mercury amalgam.
- Heat it up and let the mercury smoke off, leaving the gold behind.
This way of doing things has its charms, but it ain’t perfect. They call it “artisanal mining” sometimes – sounds fancy, don’t it? But it just means small-scale, kinda like folks making things by hand. They might not get a whole lot of gold, but they get enough to make a living, so they stick to it. And that’s why, even though there are machines out there now, you still find folks working with mercury to get that precious gold.
So, next time you think about gold, remember it ain’t just something that comes shiny out of the ground. A lot of hard work goes into it, and sometimes, folks are using old ways just to get a bit of it. This amalgamation, well, it ain’t perfect, but for many, it’s all they got. And that’s the story of how folks have been getting gold out of dirt for a mighty long time, mercury and all.
