energy for extraction of copper chromium and calcium??
« on: March 18, 2006, 07:42:54 AM »
 ???hi all, I'm still keeping on with this assignment and was wondering if anyone would know where to find the energy required for the extraction of copper, chromium and calcium?
I already have 30 – 40 million btu/tonne for copper if that makes any difference.
Thanks heaps for your help :D
