RE: RE: RE: RE: RE: RE: cost of production you are right.. somewhere i read that a cubic ft of graphite weighs 44 lbs but that is not correct
it weighs 127.86 lbs or about 2 times that of water.
so divide my # of tons by 2.9= 9.6 tons of rock to get 1 tonne of graphite.
much better numbers now.
thanks you for showing me the error of my eyes
