Click to chat· The Bond work index values and the grinding time for size reduction under 1mm were interpreted for each ore along with the values of d50 and d80 (50 and 80 passing size of the material respectively) of the ground material (Fig. 5). As expected the grinding time increased with the increasing grindability index values of the ores. It is worth to note that these findings were all in accordance with the mineralogical and structural features of ores. For instance the Bond work index for ore A was lower compared to other ores due to its over faulted and altered structure. In addition the presence of quite high amounts of relatively softer gangue minerals such as serpentine and magnesite in ore
