Hi I am doing a little work the Life Cycle Assessment on diamond mining. I am trying to find a 'rule of thumb' for the tonne of rock mined, compared to the tonne of rock processed (so that I can work out on average how much explosive is used per carat of diamond). Is there a general rule that I could apply - say for every tonne of procssed ore, it is likely that X more tonnes were blasted.
