Abstract:

A detailed characterization study was conducted on Sivaganga graphite ore deposit. The representative graphite samples of rod mill discharge were collected from the beneficiation plant of Tamilnadu Minerals Limited (TAMIN). The rod mill discharge was subjected to flotation to enrich the carbon values. The rod mill discharge and products
obtained from flotation were carefully characterarized by XRD, Zeta probe. Flotation reagent functional groups identification was carried out by Fourier Transform Infrared Spectroscopy (FTIR). The x-ray diffraction results of rod mill discharge was revealed that in the feed material, graphite, kaolinite and quartz mineral phases are present whereas in its ash sample quartz and hematite mineral phases are present. It was observed that graphite, kaolinite and quartz are present in concentrate and tailings samples like feed sample. However, only quartz phase has been observed in tailings ash sample. The zeta potential study clearly show that the combination of MIBC, ethyl alcohol and kerosene (i.e., MEK) having the point of zero charge at pH around 8. From this it is concluded that the MEK combination is work better for flotation than other reagents. Various frothers selected for FTIR study. From this study, it is concluded that MIBC yields better efficiency than other frothers.The possible reasons could be due to differences in their functional groups. Combination of MIBC and ethyl alcohol ratio of 90:10 frother provides better efficiency than the individual frother.
