It requires 2 kg of ore with a top size of ¾" (19mm). The sample is prepared by MinnovEX to have F 80 of 13 mm, and the test is run at increasing times until the time requirement to reach a P 80 of mm can be interpolated. Higher grinding time indicates higher resistance to grinding, thus a harder ore. A particle size distribution is performed

Introduction to Mineral Processing

Particle Size. The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.

Initial assaying of the six gold ore samples submitted revealed the ore to suffer a nugget effect. To overcome this, flotation tests of bulk samples were performed In order to assess the overall assay of each ore sample and the flotation performance of the ores. These tests Indicated a grind size of 90* 65 mesh would be required for gold liberation.
