In the ore processing chapter the quest for gem slurries claims that ruby slurry gives 3x aluminium and chromium compared to normal processing, and that sapphire slurry gives 2x the aluminium.

I did a quick test comparing the amount of chromium/aluminium you get from slurries and normal processing. By normal processing I mean: crushed ore -> wash -> sift -> macerate gems -> electrolyze dust.

I inputted 640 crushed ore in each processing line and got these results:
Normal ore processing:

• Ruby
  • 364 chromium dust
  • 304 aluminium dust
• Sapphire
  • 559 aluminium dust

Gem slurry line:

• Ruby
  • 320 chromium dust
  • 640 aluminium dust
• Sapphire
  • 640 aluminium dust

What we can see is that ruby slurry actually gives less chromium than normal ore processing, and that it does give more aluminium but not as much as stated in the quest.

Your solution

Increase the amount of chromium and aluminium given by the gem slurry line to make it worth building.

Additional information

At this point in EV you don't really need more aluminium and there are imo better sources than sapphire, so I don't think that is as important. However you will need a fair bit of chromium for all the different alloys you can make in the ABS, so it would be nice to get more chromium out of your ruby ore. This would also incentivize the player to build at least the ruby slurry line, since it is quite useless right now.

Also, idk if this is a GTCEu problem.

Since this is marked as Unverified, I figured I'd have a quick look. Walking through the recipes by hand and filling in the numbers in a spreadsheet, I can confirm that ruby slurry gives less chromium, and also only 2x aluminium.

Here's what I think happened: The 3x numbers check out if you do zero ore processing. If you just crush your ruby ore with a hammer and toss it in the lake like you're in the stone age, and then electrolyze the resulting dust, then yes, ruby slurry is 3x better for chromium and aluminium. But with washing and sifting, we get a lot of chromium on the side.

Johannes' numbers for sapphire also check out.

Until we or they fix it at least we should update (remove?) the quest since the slurries aren't useful right now. Does gt even use them, really? I see barely any mention if I google for it.

Yeah I figured it was a GT issue, I could change the text in the quest to say the slurries are useless. If we don't want to change the quest, I guess we just do nothing.

Something interesting about the slurries is they use crushed ore rather than purified ore, if the recipes were changed to allow purified ores then the ruby slurry would become chromium positive again from the ore washing step. Using purified ore would also be consistent with other processing lines (e.g bauxite/platline). Would still be a suggestion for GT but would be a simple change to make the slurries worth it.
