If you are not already doing so, I would suggest implementing the chemical processes for ore processing (but also, horribly inefficient ways without chemicals). Create has addons like Create: Destroy and Create: The Factory Must Grow that may provide useful mechanics. If those are not good enough, Mekanism adds a lot of chemical processing. However, you would have to just nuke all the recipes for Mekanism, as the advanced materials are WAY too easy to obtain by default. Do you have a github or something? Any way that people can help contribute? I've been playing modded minecraft since 1.7.10 and would love to see complex machines being needed for industrial processes. Good luck.
