what did ppl out for the 2 environmental and 1 economic advantage of using low grade ore?? I put: Environmental: no SO2 released - no acid rain Less energy required, less fossil fuels burnt Economic: scrap iron is cheap
Oh thank god, definitely put them for the Cu/Fe question and *hopefully* i did for the Barium one...I can't remember... Thought I'd lost a good 5 or 6 marks for a minute! Thanks!
