#Quartz Processing

Then all those years of building - were they worth anything? Yes - they're just hoping you don't realize it.

Rebecca Sugar going in for the kill with some sketches out of absolutely nowhere. Here's my best attempt at getting an okay-ish image out of a blurry vertical phone recording of a screen. Original video was posted on the official rebeccasugar account on TikTok - a big thank you to @jeejyboard for bringing it to my attention.

DARK | GLOW

They stayed up until 5 am and now it's almost 4 pm.

[edit] This was way too dark than I thought. Here's a brighter version.

thinking about this post about rose quartz (no hate to op bc this is a good post). i did get hints of this when watching future and i think that because steven universe future is mostly about steven coming to terms with his family inadvertently traumatizing him and rose being the foundation of that that steven is going to have less compassion for her and the things she left for him

steven is someone who's been hurt by what rose did although she had the best intentions and i think su future is trying to say that if that person hurt you, you dont have to forgive them or give as much grace as you normally would. that's important for a lot of traumatized people to learn in a world where forgiveness is often coerced and no amends are made. its important for steven specifically because he's been forgiving people who hurt him for literal years. him having less compassion or metered compassion instead of giving his whole self over to someone else is HUGE for him. that its for rose specifically is HUGE for him. its important to learn that you can be angry at the people who hurt you regardless of who they are or what they personally endured (in rose's case, familial abuse from the diamonds)

but like in the post thats linked, that lesson may tend to come off as mean spirited towards rose and her memory. that is a good criticism of the show because in the end rose is almost completely forgotten about, the reasons for her actions are pushed past by the finale or just called "excuses", hell some of the characters stop calling her rose and go back to calling her pink diamond. that is...mm. i didn't like that and honestly i think its indicative of the attitude towards rose that the show takes on. she chose that identity instead of remaining a diamond and as much as she admired humans for their ability to change she also changed! arguably rose's creation of her identity is a kind of self destruction that ends with steven, its motivated by love and by self hatred and its so interesting and heartwrenching to piece together. but in the end she's dead and everyone is moving on without her. its incredibly bittersweet.

i don't expect steven to be completely accepting of all of his mother's flaws and mistakes because he's in the middle of healing his own trauma and we only got so many episodes. but not casting rose in an entirely negative light wouldve been nice even if from steven's perspective and the shows message that wasn't going to happen. its arguable whether this method of forgetting rose and slowly watching her fade out of the tapestry of the show and out of the crystal gem's lives is sustainable long term. can steven ever completely put her aside and should he?

rose isnt present anymore but steven is. it comes down to whether you should have compassion for the dead or have compassion for yourself. steven choses compassion for himself but in a way i believe he also chose compassion for her. he forgives himself, something rose couldn't do. i believe she would've wanted him to

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. 👍)

Rest in peace Pink Diamond you would've loved Garma Zabi

[nikailustracion]

Just add a little few shades

Some process photos vs final result ☺

Does anyone else heavily identify with Pink Diamond and her backstory and feel sick to their stomach when people openly hate her, and then spiral into self loathing because the majority of the fandom hates her and views her as an irredeemable villain, and by extension that makes you think YOU are an irredeemable monster, and feel like the Crewniverse just made the entire show to point at people like Pink Diamond and say “Go fuck yourself and die” and the entire show nearly ruined your only real human connection with someone because of how poorly it was handled and written, and you feel like now that the show is over nothing will ever be the same again and you constantly have thoughts in your head that you deserved to die and probably should have a long time ago and you are a terrible person no matter what you try to do or say and you will forever be tainted by evil or is it just me?

Stranded at work today so I decided to sneak a draw on the workplace's computer.

rose quartz: how did she baby? Like, I get eating to gems, they just shape shift a stomach and remove the contents later, but a baby? We've all been to sex ed, you need a sperm and an egg. But rose is inorganic, so she has none, so how? I would get it if Steven is not related to Greg at all and is only a gem, but he's not so?

so because i missed out on the makeship sale of randy dialtowb i was like “oh well i can go to one of those companies that make plushies from drawings u submit!” and i drew my own randy plushie concept and waited for months and everything and,

hes uh

hes something !
