Extract

In this investigation a graphical method, based on the ultimate analysis, is applied to the classification of the carbonaceous minerals of organic origin. It is necessary in any such study to disregard those ingredients (e.g. ash-forming compounds, sulphur, nitrogen, and free moisture) whose presence, while greatly influencing the commercial value of a carbonaceous mineral, has no significance in regard to its classification. These extraneous or adventitious ingredients have therefore been eliminated by calculation, so as to reduce each analysis to terms of its essential elements—carbon, hydrogen, and oxygen.
