Sasza22 Posted June 29, 2019 Share Posted June 29, 2019 I know we shouldn`t worry about the game being too realisitc but that one made me think a bit. Real life aluminium is 90% recycled metal since refining the ore is way more expensive than reusing scrap aluminium. But in ONI aluminum is like copper, easily refined in the rock crusher. First thing is that i didn`t expect it to get added but if it was i thought of it as a later tech metal, more advanced than iron somewhere around steel tech. Space shuttles were build out of aluminium beacause of it low weight. This isn`t really bothering me as unrealistic but more as a missed opportunity of having another steel tier metal.

metallichydra Posted June 29, 2019 Share Posted June 29, 2019 it would be really nice if metals had weight … i mean, those tables must be much smaller when made out of 200 kg of gold, compared to 200 kg of aliminium Link to comment Share on other sites More sharing options...
Gurgel Posted June 29, 2019 Share Posted June 29, 2019 Well, the thing is that real-world Aluminum production uses a _lot_ of electricity. That is why so much gets recycled. I am also unsure whether a completely separate manufacturing chain would make sense. Link to comment Share on other sites More sharing options...

That's because aluminium in nature is bauxite. Greatly simplified it's rusted aluminium where it is together with mainly oxygen and hydrogen. You can create pure aluminium by melting it at a high enough temperature, but heating it that much cost energy. Creating 1 kg of Al from "ore" takes the same amount of energy as recycling 5 kg. Iceland is a big producer of Al (relative to country size at least) because building geothermal and hydro powerplants there and the ship transport is cheaper than getting that amount of electricity from fossil fuels. Relative to the amount of electricity needed for the heating process, the ship transport is basically free. 8% of Earths crust consist of bauxite and we are not running out. The recycle is only due to energy and financial costs. From an environmental point of view, it's one of the places where recycling makes the most sense due to massive amount of energy needed in the process.

As far as I understand the process, the melting is not the issue. You have to do electrolysis in addition, and that is where almost all the energy goes. Historic tidbit: Before the melted electrolysis process was invented, they produced it chemically, with the result that prices were so high people wore the stuff as jewelry.

Sasza22 Posted June 29, 2019 Author Share Posted June 29, 2019 Mostly i thought about it not being refinable through the rock crusher but instead could be melted in the metal refinery (maybe requring something extra) and the resulting aluminium having some sort of better qualtiy like extra overheat temp and could be used similar to steel (at least for buildings that require metal ore).

If not i would say just consider it one more random metal and the same as copper. I hope it will be integrated more tightly. Link to comment Share on other sites More sharing options...

You have to do electrolysis in addition, and that is where almost all the energy goes. Reading that made me go "that makes a lot of sense" and I went to google the process. It looks like Al is first treated to get rid of impurities, but it then has an electrical imbalance, which makes the Al atoms stick together. To get them to become free atoms (hence usable), they have to be liquid and then high current flows through to move electrons around to bring each Al atom to become electrical stable. However this doesn't change the fact that an extreme amount of electrical power is needed. It's also still a fact that the amount of power is so great that production is placed where power is available rather than where workers are available and transport costs doesn't really matter. 26 minutes ago, badgamer123 said: damn why i would learn some IRL stuff in a game lol Apparently I learn something too.
