Ore processing in gregtech is a little different than mekanism. In gregtech you process ores to get secondary by products (or more). Mekanism you just process to get multiplicative output. So if you process and ore like ruby you can get other materials out of it like Chrome. Where as in Mekanism if you fully process gold you get 5x gold ingots. I would go into more detail but I'm in class on my phone.
Here is a link to all the ores and the byproducts you can get out of them with proper processing.

Thanks for the link, now I have much more todo as tought - But I'll give my best to get those byproducts which I rly need, other stuff can go into Mekanism's x5 processing.
GT ores can only be processed by GT machines mostly anyway. Mekanism or other mods have only <10% of the GT ores and can't process the other stuff. Also in some cases the byproducts are more important, so again you need GT oreprocessing. For the few things you can process with mekansism building a processing line is not worth the work.
I don't think so since Mekanism changed the work for the Solar Evaporation Tower compleatly an labled it new as Thermal Evaporation Tower, also the recipes have changed so you can easiely go to x2/x3 and since that we have Draconic Evolution in the MP x5 is important for this because actually we don't have the power to run a world with draconium ore in RFTools. This is my meaning for this :).
Well, nobady which has any idea for the AESU and IDSU?
