Summary
GregTech has a very elaborate and systematic ore processing system. It's based off of IC2's with the crushed/purified ores and dusts. I made this flowchart to cleanly visualize all ways to get from ore to product. At each step of the process, it is possible to acquire byproducts of that ore, which appear in NEI under "Ore Byproduct List" or on the official FTB wiki page on GregTech Mining and Processing. So let's make a system that does all this. It's going to be expensive (I list the total number of require machines at the end) so I hope you have a good supply of stainless steel and some diamonds and/or tungsten.
