Native Silver (tarnished yellow) overgrown by Nickeline (pink) and Rammelsbergite (whitish grey rim on Nickeline) and Gersdorffite (light grey, euhedral crystals) and partially replaced by intergrown Acanthite (dull, scratched grey) and Stephanite (slightly lighter, "cleaner" grey)

Locality: Easter-Duffy Deposit, Greater Slave Lake, Northwest Territories, Canada

Plane Polarized Reflected Light, 50X Magnification

Have not had time to take new pictures of my newer rocks, as I have been super busy working on my MSc, so I thought I would upload some reflected light images from my thesis! If it seems like these are something folks want to see, I have loads more where this came from. Plus tumblr has a lack of reflected light microscopy images anyways. Feel free to reach out if you have any questions about this stuff!

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. 👍)

#Mineral processing is like- the pinnacle of geology in my opinion. I feel so biased saying this! lmfao. I love it though! It's why it #matters if you have Bornite or Chalcopyrite in the ground; or if your ore deposit is in an ophiolite or a porphyry; or if your gold is in a #quartz vein or a fault zone. If your gold is stuck as native in quartz you might not be able to get it out!#To be clear I'm a geologist too. Technically in engineering because that's where this stuff is taught but I identify as Geologist~#mining #mineral processing #geology #I hope I didn't talk too much! I tried to give a good explanation without teaching a class. It's so much info. lol

I was rewatching one of the MRE power hours and I love how different Arin and Dan's thresholds for food are. Like, Dan rejects food that objectively sound delicious but Arin draws the line at "yeah no dude this is literally poisonous" LMAOO

#had this thought after rewatching the episode with the mini heater specifically #when dan rejected the chicken fried rice MRE but was raring to go with that blueberry cobbler and arin had to be like #“no dude i'm pretty sure we can't eat this. i think the chemicals from the heater got in it and it's toxic as fuck now” LMFAO #oh aron... arin “mineral deposits and BPA” hanson how we love you so /gen #game grumps #10 minute power hour #10mph #arin hanson #dan avidan #food mention #my posts

I love when I see a long DNI list with a bunch of words I don’t recognise on it cuz I just know I’m about to discover a new identity label

And yeah I’ll be a good little bunny and not interact or bother folks because that’s just fine by me, it’s nice to know up front that we’re not gonna get along

(If you have a long and curated DNI list we’re not gonna get along that’s just the facts I don’t need “list all the things I hate” energy in my life)

I will give it to ya though, it’s a much better and safer idea than listing all your triggers - but I could probably backhack it and make some key guesses and that’s not good

#brought to you by googling someone’s dni list for fun #and spending 2 whole minutes wondering who tf identifies as a geology term for things formed underground #i wanna be a mineral deposit #the only acceptable dni list is that one tumblr post of dni if you use tumblr

Just Desserts continental northern map made using this method! :D (Patreon)

#My art #Just Desserts #The JD residents all live on the northmost landmass in the middle green area - which I've been calling The Basin #It's a fairly flat area that has a very extreme mountain range to its north #They jut up extremely and then clifface on the coastline - keeps the Basin very protected from high moisture!#I've mentioned before how the JD universe doesn't really have summers - I mean that's Partially true #The Basin only experiences three seasons but the more south you go the more seasonal variation there is #But Residents can't stand the heat - even ones that are pastries that would require heat to bake don't fare well day after day #So none live in warmer climes! Other things do tho :)#It's funny to me how piecemeal this idea came together haha #The map-making trick is hecka cool! And it was definitely the push I needed but there are other bits of this that fell in line first #Most especially the fun little idea that I've doodled here or there and talked about in bits and pieces #Of how since the residents are candy that they mine teeth like cavities haha - it's canon now! >:3c #The northern mountains are the silhouette of the lower half of a human jaw! And with how they jut up - the mountains are shaped like teeth!#The Basin is the basin of the mouth/jaw where the tongue would normally be - the tasty bit haha #And residents do have a calcium-mining industry up there - and if the deposits happen to form in a specific shape well ♪ Hehehe #I'm still parsing what I'd like the mineral to Do exactly - it's more likely to be a building material than a food item but hmm #Why would they have such a need for it! Something more to consider #For now it's just a fun idea that finally got put to reality hehe ♪ And it was a fun thing to work on! :D #I'm not sure yet of what other landmasses might be around - maybe this is the whole world! - or what other fauna and flora there is #I'm back on thinking about Elemental Magic so there's that lol I can't help it #I'd like for the JD universe's magic system to be a little more defined :) Every little step helps!#See if you can identify the other silhouettes I used! :D

If muriatic acid won't clean my dang toilet, I will make a whole sideblog for that piece of garbage

#non sims #rl stuff #I have been cleaning that toilet Intensely for the last three days and I have barely made a dent #for clarification: my toilet is that way because of the previous inhabitant. I did not cause at least a decade's worth of mineral deposits #the sheer amount of acidic things I have already used is crazy

Alive and awake but at what cost, really?

#[ ooc. ] don't try to make it logical or edit your soul according to the fashion. rather; follow your most intense obsessions mercilessly.#[ my coffee machine is half-broken. well not /broken/ but continuously stuck with mineral deposit i think. ]#[ i hate technology; let me be able to force it to do a mineral deposit clean thing. or a deep clean. why do i need to wait. ]#[ for it to tell me it's needed-- IT'S OBVIOUSLY NEEDED I CAN /SEE/ it in the tube!! but i can't get the tube loose. ]#[ technology please. ]
