RE:88 tonnes of waste for 1 tonne of graphiteHave to burst your little balloon again Alex, the limstone morphed marble is calcium based, not Kilmar Dolomite which is a magnesium based depost and every ton is Portland cement grade feedstock. Or, it is also recommended by the Agri Center, Montreal as an effective acid inhibitor, and soil conditionner. Not one pound of waste at all. The company that wants to put the cement kiln in at Van Leek hill wants every pound of it! No waste Alex, all pay dirt! And there are two more cement kilns in the province Alex and both need limestone derivatives! Sorry for the bad news!
