Read MoreThe bond work index of granite is expected to be the highest due to the ore being mostly composed of the hard mineral quartz. Bond Work index values of granite presented in literature range from around 14-15. Limestone is theorized to have a Bond Work index with a value of around 11. This is due to the main presence of calcite, a softer mineral.
