I think that there should be possible to enrich dark ores in the enrichment chamber, vanilla diamond ores and lapis lazuli can be enriced into dyeBlue/lapizlazili dust and diamonds into diamond gem.

Why? It's railcraft that is addin the ore, so have it here makes most sense. You have integration with other mods right?

I already register the Ores with the Ore Dictionary, any further integration would have to be on the Mekanism side.

Ask aidan instead of CJ.
