This definitely reminds me of Tungsten processing chain. And it makes sense, since Tungsten is directly below Molybdenum on the Periodic Table, right?
And it also leaves the question about Chromium, which is above Molybdenum. At this point I think it’s reasonable to say that such complexity would certainly be overwhelming, if applied to such an early-game material. And breaks progression, since you need Chromium for Stainless Steel for Mixers for Chemistry.
Stainless Steel is produced from Ferrochromium (which is reduced from Chromite) instead of pure Chromium though. And making it more complex to get Chromium than Ferrochromium could actually make sense, since Chromium in GT6 is higher tier than Stainless Steel.
Personally I have more trouble finding a Chromite vein anyway.
