Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.

SEGREGATION TREATMENT. The minus 10 mesh ore is mixed with approximately 1% of common salt and the same quantity of fine coke. Granulometric size of common salt is not important, although for better mixing fine salt is preferred; the coke should be ground to at least 48 mesh. Also, for proper segregation, the ore must contain some 23% of moisture.

the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water and initial flotation reagents to form slurry. The ore is then ground in rod and ball mills. The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semiautogenous mills (steel balls are added to the ore).
