Quantification of graphite in BM is necessary for designing recycling strategies for graphite using processes such as froth flotation. Commonly available techniques such as ICP techniques (Inductively Coupled Plasma), MP-AES, and XRF (Xray Fluorescence) are not able to determine the amount of carbon due to its low atomic number and inefficient ionization in plasma. TGA/MS running in an oxidative atmosphere is used in this study to develop a reliable method for approximate quantification of total carbon in BM samples. When NMC BM is heated under excess O2, the thermodynamics of the process change compared to heating under an inert atmosphere, and graphite does not take part in the reduction reaction. The presence of excess O2 during TGA/MS instead promotes the combustion of the organic material and graphite resulting in the formation of CO2 and CO, as shown by equations ( ) -( ). 21
