wait no please explain mineral processing!!!

I gasped in delight at the ask, haha. I love mineral processing.

Mineral processing is the theory of economically getting your desired element out of whatever it naturally comes in. So Li out of spodumene, or Cu out of chalcopyrite. It's usually split into hydrometallurgy and pyrometallurgy (liquid chemistry and melting the fuck out of it, respectively), and often taught as hard rock extraction, but you need it for Every Element, really. So you can also focus on extracting phosphates, or nitrates, or uranium! It's chemistry++~

Personally, I know the most about copper extraction and my focus is on hydrometallurgy/geometallurgy, although pyrometallurgy is near to my heart. Copper is coincidentally a really good example of how the two work because it comes as so many natural minerals. (Further explanations under the cut...)

So for copper minerals! You have a whole slew of oxides and sulfides. They occur in different part of your orebodies under different states of oxidation/sulfidation. Take Chrysocolla, Malachite, Chalcocite, and Chalcopyrite. (Cu-silicate)(an oxide), (Cu-carbonate)(an oxide), (Cu-Sulfide), and (Cu-Fe-Sulfide).

Mines usually use hydrometallurgy for oxides by sticking them in a leach heap and pouring sulfuric acid over the whole thing. The acid selectively picks up the Cu ion from silicates and carbonates, leaving the primary tetrahedra alone. The sulfides can work with this chemistry if the mineral's comfort zone is outside of the current conditions (Chalcocite does leach, but usually leaves a Cu ion in the structure as CuS) but minerals like Chalcopyrite are very poor leachers because the outer rim of ions are ripped away, leaving a somewhat-hypothetical "passive layer" of Fe/S that won't react with the acid. So if you have a mine with a lot of Chalcopyrite, you'll be leaving money on the table unless you do something.

So people use pyrometallurgy! Which is what we've been using since the Bronze Age, really. You crush the rock to micrometer grains, use the hydrophobic properties of sulfur to "float" the sulfides in water, then send all of it to the smelter and melt the shit out of it, while adding particular chemicals and minerals to enhance copper recovery while suppressing sulfides you don't want, like sphalerite and galena.

It's REALLY cool. I'm biased of course, but I absolutely love the whole cycle. xD Being in mineral processing also gets you on the backside of geopolitics because you're the only person who understands how to GET things and WHERE to get them and why it's not as simple as pulling Cu out of the ground.

Feel free to ask questions!! I love processing so much, and mining in general, even though I'm only a master's student.

((And NO STUPID QUESTIONS. The mining industry is a goddamn black box DO NOT feel bad if you don't know what stuff means or formulas, or processes. I swear I learn one new word a week. They also have fifty names for everything too because 50 names are always better than 1. 👍)

Look at this big boy i found in a shop while on vacation in medocino county over the weekend (and it glows under UV light!)

[reddpenn]

I love super colorful rocks/minerals like bismuth and quartz. Any others like them?

Chalcopyrite is pretty neat!

Also known as "peacock ore," chalcopyrite is an ore of copper. It doesn't come out of the ground with these rainbow colors; in nature it actually has a brassy color similar to pyrite! To get the rainbows to appear, it first has to be given an acid bath to strip off its outer layer. The newly exposed surface will quickly oxidize, forming a rainbow patina!

While spellcasters can easily extract the magic contained within arcane crystals, forging said power into something less volatile requires a great deal of skill. Some artificers have managed such a feat, though, and have built weapons out of them. Magical blades are often far more effective than most non-enchanted metals.

Second sword for Swordtember! This time I got to mix holographic (as in hologram) and some iridiscent materials, such as titanium quartz and tarnished chalcopyrite. I also pushed that cyberpunky vibe here. This one now belongs to @rbillustration, but if you're interested in others, check out this post!

Shiny's rock + how it fits into FNaF

I realized the research/prep I did for 'The Imposter' so now I wanna ramble about it bc i think i deserve it? [in defense of shiny] [The Imposter fic]

The first time Shiny brings up rocks it's when Sun freaks out about them leaving and possibly not coming back. Shiny pulls out their 'worry stone' and gives it to him saying that it's too important for them to not come back for it. They also mention it's to help find lost things, so Sun will find Shiny tomorrow at work.

A worry stone is something that a person keeps on them and rubs every time they are stressed, resulting in smoothing the stone over time. However, Shiny's is large and bumpy, meaning it's new and wasn't meant to be one.

It's Chalcopyrite which is a stone that can be used as a compass to find lost items/people and help increase psychic abilities and intuition. Shiny explains why they carry it around but there is a misunderstanding between them.

Shiny brings up another stone. "That's Hematite! Good for remembering things and getting rid of bad energy." Which, yeah, but it's also known as the bloodstone, used for grounding, stability, and focus(memory).

Quartz is an all-purpose stone that Shiny gives to the little girl who was hurt in Chapter 13. It enhances other crystals paired with, but it also is fantastic for memory.

Lapis Lazuli is another memory stone helping with communication and sharing information.

Blue Chalcedony is said to be used for memory enhancement, but mostly storing information.

Most of Shiny's stones are based on searching for things and remembering, which makes sense because they have DID and do not have ANY of their childhood memories, Imp does. Imp also refuses to talk with them, so it could be seen as an attempt to try and remember by themselves. A few of these double as 'clearing away evil spirits/negative energy', which hm... wonder what that would affect in the plex.

So that brings me to... what is a key part of the FNAF lore: Remanent that is used when making the animatronics to trap souls in them. Basically just 'soul energy' and something talked about in scriptures. So metaphysical energy already exists in the FNaF universe and the ImpAU is going to use that.

Also i swear to fuck they're gonna kiss, I didn't bait and switch. They gotta suffer for it. The main plot is about child abuse and psychological horrors.

Ironically Imposter pushes the relationship story but has to traverse the main plot. Shiny experiences the love story but pushes the main plot.

This doesn't get into Imposter's contributions, lemme know about that bc i talk WAY too much. Thanks for coming to my Ted talk.

It's also important to know that Imposter doesn't know jack about Shiny's rocks and neither do Moon/Sun

Writing about Mines in your Fictional Universe: A Geology Introduction

Hello! I'm Bird, and I am here to guide you on a journey about different mines that exist, what materials are being mined, what those materials might be mined for, and what rocks/what processes might make these areas mineable. I will also touch briefly on the idea of gem quality, the commonness of the material, and what these things might look like fresh out of the dirt!

First things first, lets talk about the what types of things we might want to mine for in a fictional universe! There are a lot of things that are used daily that require mining, but there are a few that I see written about the most: Gold, Gemstones, Iron, and Coal. I personally would love to see this idea expanded on a bit, so lets talk about some mines that would definitely be necessary but overlooked! First one is pretty easy, glass! those beautiful stained glass windows are useless if no one is mining quartz to be made to glass, and I imagine it would be quite a profitable business seeing as glass, in general, was a luxury in ye olden times. The next thing we need to address is Abrasives! want to sand and polish stone and metal? Want to sharpen your blades for battle? May I introduce you to abrasive minerals! garnet, corundum (Ruby and Sapphire), and yes, diamond! Why are we using such beautiful gemstones to polish other things? Simple, even if you are to find a deposit of these gemstones (garnet being one of the more common ones) most of the time they are inclusion rich, ridiculously small, an undesirable color, or all three of these.

Finding gemstones that are good quality is hard, your character will not stumble upon it, pick up the rock and immediately know if the location is good enough to mine gemstones. If you are determined to make it a gemstone mine, have your character hold the mineral up to the sun/a light source and let them be able to see light coming through, though it is considerably thick.

Moving into metal mining! Metal mining is both easier and more complicated to write! Why is it complicated? Because unless it is gold or silver you are unlikely to see the desired metal itself. Why is it easy? welllll, I am going to try to make it easy. First things first, a lot of metals are chromaphores, this means that when the element is present, it will influence the color! Copper is an excellent example of this, old pennies oxidize and turn blue/teal/green, so do most rocks bearing copper! Looking for iron? It will probably stain the rocks dingy and brownish red. Things to note: copper and iron can be found in mineable amounts together! If you do this, iron will be present in the form of pyrite, or fool's gold, this has a nice cubic shape and can be described as such, the copper will typically leave a teal residue or veining across the rock, which in this case will almost exclusively be black to dark gray (Its basalt) but it can be found as the mineral chalcopyrite also (looks like fool's gold but it doesn't make cute crystals). Malachite is also a copper ore, in my experience I have never seen malachite from a mine that has looked like some of the stuff I have seen in gem shops, azurite (A darker blue mineral) can be present also, but again, these are usually very fine grained and would not be able to be used as jewelry, but obviously, in some places it must happen, just much less frequently.

Another thing I will briefly mention is that, if you are writing about metals remember that these metals will require a smelting process to extract a pure metal, this usually requires some other material (For iron, it is charcoal). Also remember alloys! Most useable metals are a mix of different metals to make them harder. This even includes gold jewelry. Last comment about metals, a very interesting plot for a fictional universe would be the use of lead. Lead ore was a hot commodity before we knew it was toxic, the side effects (Being nuts) could really create some tension.

Lastly in terms of mined material, I will briefly mention coal and stone in general just to say, coal is a sedimentary rock, distinctly different from the typical environments necessary to form most gemstones and heavy metal deposits (Yes, there are exceptions). Coal is dark black/gray, which is quite uncommon for sedimentary rocks which tend to range from reds/tans/browns/grays. When coal is lifted it will feel much lighter than you anticipate, which is the polar opposite of what happens when you lift a metal rich rock, which will feel immensely heavy. Finally, Coal will not turn into diamonds in nature, diamonds need mantle pressures and temperatures to form, there will be no diamonds under a coal mine unless there was a mantle derived eruption that got covered in a swamp, that became coal and as they dug they exposed the kimberlite pipe (I mention this because I just read this in a story and it hurt my feelings). Finally, If you want to write about a mine that is definitely necessary but want the content to be pretty low-maintenance, but profitable for whoever owns it, owning a granite/marble/ or really any desirable stone quarry would be perfect.

Now I will move onto what kind of mining exists today, I will not talk about every exclusive mine, but I will talk about ones that are common that are on my radar. First up, the one everyone talks about in books, underground mining. Underground mining is used when you are getting the material from the 'primary'/original source. The rock is rich in copper? Lets mine said rock. However, mining underground is the most dangerous form of mining, there can easily be a lack of oxygen because of insufficient ventilation (That's why people will carry something with an open flame when going into abandoned mines; if the flame goes out there is not enough oxygen and you have to turn back). There can also be lots of collapses due to overhead rocks, enough said. Cave mining is primarily done when the amount of rock above the deposit is too great to strip mine.

Now lets talk about strip mining! Strip mining is when you just mine on the surface, and dig deeper and deeper into the ground to obtain your desired resource whether it be stone, coal, gemstones, or anything else. It truly is less glamorous, but it is safer than digging a tunnel. That said it has its own issues, sure the oxygen is good, and you don't have to worry about the rocks collapsing over your head, but oh wait, the rocks can collapse over your head. Landslides can occur due to the over steepening of sides, excessive rainfall, and most importantly, old faults or planes of weakness that happen to be facing towards the mine (the diagram will help this make sense). Both of these types of mines can also create ecological damage, which can be mitigated nowadays, but then maybe not so much. Namely acid mine drainage, I will not talk much on the effects but a quick google search will give you plenty of information that might be useful for writing.

Now both of these are trying to mine a targeted rock, but sometimes its best to let nature do the work so we can do less. Diamonds, gold, corundum (rubies/sapphires), and garnets all have one thing in common. They are dense! So when erosion happens, and that sediment makes its way into a river, everything will separate based on its density. This is just because faster moving water can hold heavier sediments, and slower moving water will drop those heavy sediments leaving only the lighter sediments within the water. Lots of places that mine the things listed above will pan/sieve in active rivers and streams, or they can surface mine where rivers and streams used to be! These are called placer deposits. There is one setback though, the gemstones will not be perfect crystal shaped, they will be rounded due to being thrown around in a river (like beach glass). These are sapphires, but they have been rounded over time in the river.

Final thoughts, writing about a mine can seem nerve-racking, intimidating, or just something that you want to briefly mention and move on from, but truly I think going into the weeds could really add something to a story! Even if stories are slightly inaccurate about information, I am still 100x more excited to see it mentioned in more detail than to see it as a sentence. Besides it is fantasy, it doesn't always have to be exactly like earth.

Grabbed this in SF a couple of weeks ago after finding a store that intersects with several of my interests: bugs, minerals and plants (plus taxidermy and other sorts of remains including human skulls).

Ricky: “this store is laser targeted at you”

I think chalcopyrite (or pyrite) and quartz is one of my favourite mineral combos.
