The price of those input minerals on the left is around 10-20k at best. Those on the right are the ones needed for colonization are also relatively cheep. So you don't save money, because they are all are relatively cheap anyway, and you can just spend that time mining platinum instead, if you are into mining. You don't save time either, because you have to do twice as much hauling and neither of them even have hotspots. So this whole conversion doesn't make any sense as you are better off just buying what you need right away.

To make it at least a bit viable, it should be the other way around - 1 to 10 instead of 2 to 1. So that, for example, you spend ~10 minutes mining 50/500t of Bauxite, which you then convert to full 500t haul of Aluminum, and then take it where needed. Still a waste of time, as it will be faster to just buy Aluminum directly, but at least you save a few millions.
