Abstract

Sample from Doomara: A low grade graphite sample from Doomara village, Ajmer, Rajasthan, received for beneficiation tests, assayed, C, 8.19; Ash, 84.37; volatile matter, 4.92; and moisture, 2.52 percent. The gangue minerals present in the sample were mica, quartz and tourmaline with traces of calcite. Graphite was found to be intimately associated with mica even at 200 mesh and therefore a high grade of graphite concentrate obtained after one reflotation assayed 56.65% ash indicating that it was not possible to produce even foundry grade graphite from the sample. Sample from Lotiyana: This sample was of a lower grade than even the one from Doomara and graphite in this also was very intimately associated with mica even at -200 mesh. It was not possible to produce even a low grade concentrate for foundry purposes. As received the sample assayed C, 2.17% Ash, 84.03%; volatile matter, 13.52% and moisture 0.28%.
