    H 2 Generation In Wet Grinding Of Granite And Single

    Abstract. Granite and single crystals of quartz, alkali feldspar, biotite and muscovite are ground in pH-controlled and pure water solutions using a ball mill at ambient condition to examine the production of H 2.The amount of H 2 generated by grinding is linearly related with the surface area of ground samples. The slope of the straight line indicates H 2 productivity of each mineral 3.9 ...
