Abstract
This is an experimental work on a local oolitic iron ore deposit. The objective was to determine the operating conditions of batch rod mill operations which yield maximum liberation of the oolites from the cementing gangue minerals. The recommended operating conditions were expressed as size of crushing rods, rods/ore mass ratio and time of operation. Also calculated is Bond's constant to be used for estimating the power requirements of large mills. Scaling up of the results could be done using Gow's formula.
