This potentially blocks the sulphides that are formed during the desulphurisation process to reach the slag phase thus hampering the desulphurisation efficiency. In this research it was aimed to obtain experimental evidence for the postulated hampering effect of graphite on the hot metal desulphurisation efficiency at an industrial process.
