Liberability: A new approach for measuring ore comminution

The grinding test was performed by using the Capco jar mill 337SS with ball charge 1.3 kg and average ball diameter φ 28 mm. The target P80 should align with the Bond tests and therefore 17 minutes grinding time was used for the MINeRAL PROCeSSING. Meschac-Bill Kime Arthur Kaniki. Grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. Twelve mono-sized ore fractions were prepared and wet ground batchwise. The mill was run for 0.5 to 30 min intervals. The shortest interval provided data more closely related to the breakage MINeRAL PROCeSSING Academia.edu
