6.4 kWh/t. Higher values of the Bond Work Index are achieved in 2 samples and the same amounts 7.059 and 9.526 kWh/ t. The increased value of the Bond Work Index in these samples of limestone is explained by the presence of white-yellow limestone cores and increased magnesium content. Keywords: Bond Work Index, limestone
