Iron : Copper Ratio

[stm]

Is it just me or are ore requirements for sience heavily weighted for iron?
red: 2:1
green: 5.5:1.5
grey: 14:5
blue: 24:15
violett: 157.5:57.5
yellow: 33.3 :49.8 (finally one that uses more copper)
white: 44:101.8 (Ok, this uses sinificantly more copper)
total:280.3:231.6
In total (averaged over all equally, since space sience has no use on its own) this gives a need of 21% more iron than copper and in the beginning this starts out a lot worse.
But nevertheless iron and copper are of similar abundance by default. Even heat-pipes use more than twice the amount of iron than copper.
I liked the change that stone is needed a lot more than before, but you always had the possibility to use it for walls or concrete (which incedently needs even more iron)
So what am I supposed to do with all the surpluss copper on the map?

Nice Links, which I had read already when they came out, and which do not answer the question what to do with the surplus (exept maybe play on expensive)

This should be untrue, except if there is a bug in map gen. On average, with identical settings for both iron and copper, mapgen gives appropriate ratios to match the need for science.
I insist that it's on average, so it's not always perfect balance.
That's why the links answer to your questin : if you explore a big enough area of your map, you should get good ratio of iron:copper.

You don't have to mine it, so if you don't want it, you can just ignore it.

Install one of the many mods that give you an "ore eraser", and delete the offensive copper ore.
