Is this right? In this mod iron is like a"red color" and cooper is "blue?" In main game cooper is like red/orange and iron is blue, in mine moded game color are changed, or its right in this mod?

Yes, its correct, that its switched compared to base game. Its supposed to be more realistic

but the icon is still the otherway round...

Icons should be fixed in the upcoming version, thanks for pointing this out. Iron oxide is red and chalcocite (copper(I) sulfide, one of the many ore minerals for copper) is bluish-gray.
