Okay... so here's some suggestions regarding ores and resources:
Suggestion Topic: Silver Ore
So right now, silver is made from centrifuging gold. It would be nice if it was actually generated as ore. I'm not sure if silver ores have been suggested and rejected before, but if they have, a reason for why would be nice.
Suggestion Topic: Electrum
Apparently, electrum is a real alloy of gold and silver. It also naturally appears in the real world. It could be used for cables, perhaps same tier as gold and slightly less lossage, since it's a good material for wires in the real world. (citation needed) It could be generated as ore or crafted with silver and gold dust, perhaps 1+1 or 3+1 like bronze.
Suggestion Topic: Uranium
Right now, doing the full ore processing for uranium ultimately yields 6 uranium 238 + 1 uranium 235. It would be nice if there would more 235, and maybe even at the cost of less 238. Because now the unbalanced ratio of 1:6 causes a lot of 238 to be left over in crafting enriched fuel, and the leftovers just get thrown in a chest and forgotten about.
Suggestion Topic: Stone Dust
Stone dust is something you get from ore washing and use for CF foam (probably that's the only use). It would be nice if compressing 4-9 stone dusts gives one block of smooth/regular stone. As some one who basically only uses CF for reinforced stone, all of my stone dust either gets thrown into a recycler or sits in a chest.
So that's it for now, I might add more suggestions if I think of any.
