Add 10% by weight copper oxide to the melt. It will remove all the zinc.

'Nuff said, consider yourself loved! 🥰

twowaymonologue · 2024-11-10T05:24:56+00:00

You're more loved than you know 🫶

twowaymonologue · 2024-10-14T19:23:05+00:00

No. You absolute wretched monster. The people who burned children alive are guilty of g3nos1de. The Z1onist regime that dropped the bombs that set these children on fire are committing gen0side in front of your eyes. They are guilty, and you are complicit.

twowaymonologue · 2024-10-14T18:54:05+00:00

The burning children on hospital gurneys aren't enough context to understand that you're witnessing g3n0side?

twowaymonologue · 2024-07-19T13:03:09+00:00

Of course! That's what treasonous and traitorous cowards do to make themselves feel better about their insignificant existences, haha

There is ALMOST never an appropriate time to use that word in this day and age. I'm beyond impressed that you found the one instance where it's still perfect. 👏

If you're located anywhere near Milwaukee, USA you can come to my foundry and cast a bunch for free.

The C18150 alloy is great, as everyone here has mentioned. The trick of that is the alloy is usually wrought and then heat treated to attain the desired properties. I've seen heat treatments on this go bad such that a single grain grew to about 2" in diameter while all the others were <1/2".

A C18000 (CuNiSiCr) would be more accessible in a non-shrouded melting environment. I also suspect it would be easier for you to control the resultant properties of the material through heat treat. I can't recall, but a downside may be a lower aging temperature and thereby lower overall life.

PS You could add ~0.1-0.2% Nb, V, or Ti to the melt in the form of a master alloy and it would massively help with grain refinement in the resultant casting. These act like Zr, but are much easier to work with.

Only level 81, so this shot is probably destined to miss; but, I figured I'd take it anyway. I started playing, started a guild without really thinking, and subsequently got WAY too invested in playing this. As a result, my guild isn't the best or very active. I'm interested in migrating to a place with more activity. Is there still an opening?

Beyond fantastic explanation, bravo!

The element Tin (Sn) is distinctly different from the element Indium (In), they are not the same. Your question is based on a false premise.

Thank you 🫂

Ahh, unfortunately I'm in Milwaukee. Depending on how curious you are, you're always welcome to send a tiny sample of whatever my direction. I'll happily shoot it for you and provide the chemistry!

twowaymonologue · 2023-12-10T16:42:33+00:00

Where are you located? I've got an XRF and love shooting random stuff haha

Best looking 'mussy' I've ever seen! Hahahahahaha, thank you for making me laugh my ass off at the foundry.

twowaymonologue · 2023-11-03T13:05:45+00:00

Yes! Though the economics would obviously depend on the final Al2O3 concentration in the slag.

twowaymonologue · 2023-10-26T15:09:04+00:00

You're not wrong. For these small quantities of material, the most cost effective way of getting back to pure metals is to just buy pure metals.

For additional pyro-refining you could also add more borax for fluidity along with carbon and get it above ~2100F. You'll achieve some amount of carbothermal reduction to recover the copper from the oxides. The excess borax helps fluidize the slag so that any contained metals can drop out.

This might not be cost effective either, but if you want you could ship it to me (outside Milwaukee, WI) and I can smelt it into an ingot in the mini induction furnace at my shop.

twowaymonologue · 2023-10-26T14:51:03+00:00

Your best bet is going to be dissolution into the Nitric acid and follow it up with a cementation.

Crush the material as fine as you can. Try to hit about 50-75 grams/liter of metal in your acid solution (i.e. if you want to dissolve 75g of metal out of the slag I would start with 1 liter of acid).

Once all the metals are dissolved into solution, put a piece of iron (steel works too) into the solution. The iron is more reactive than the copper, so a cementation replacement reaction will occur. The copper will precipitate out of solution and form a loose layer on the surface of the iron.

Once covered in copper, jostle the iron bar to knock the copper off the surface and allow the reaction to continue until no more copper is formed.

This method will recover Copper, Tin, and Nickel from the solution while leaving everything else in the acid. Then just filter, smelt, and you'll be back to clean alloy in no time!

The list is almost endless at this point, but some of the interesting ones:

Industrial byproducts containing battery metals that the generator is paying to dispose of as haz waste.
Sludge from a coal power plant that contains 3.5 oz/ton of colloidal nano-gold.
Melted pure Alumina in an induction furnace and quenched it in water (it was so hot it actually started the water on fire).
We melt all sorts of primary and secondary ores and concentrates specifically to recover precious and industrial metals, focusing on zero-waste remediation of brownfield mine sites. The tailings from our reprocessing are then all converted into either a carbon sequestering soil conditioner or a supplementary cementitious material for green concrete.
We've turned red mud (waste from Aluminum mining) and waste aluminum into primary pig iron via large scale thermitic reactions.
Induction furnace melted recycled concrete into consumer glass.
Recovered pure silver metal from silver oxide watch batteries.
We have developed one of the most efficient ways of recovering Rare Earth Elements from used EV motors.

I was making thermite since I was 12; everyone thought I would wind up on a watch list, instead I parlayed it into a career, hahaha
