The Effect Of Regrinding Chemistry And Particle Breakage

Regrinding rougher flotation concentrates is typically used to liberate valuable minerals from gangue prior to the cleaner separation stage in processing of low grade ores compared to the rougher flotation after primary grinding it is usually more challenging to achieve a satisfactory

Copper ore grinding porphyry copper ores usually are medium to medium hard and require grinding to about 65 mesh to economically liberate the copper minerals from the siliceous gangue sometimes a regrinding circuit is advantageous on the rougher concentrate and on the scavenger concentrate

For the porphyry copper ore tested in these investigations a coarse copper sulphide grain size coupled with a high association with hard microwavetransparent ie quartz and hard microwaveheating ie pyrite minerals resulted in a grind size increase of 5060 m for equivalent liberation or an approximate 25 increase in liberation at an equivalent grind size

Porphyry copper ores usually medium to medium hard require grinding to about 65mesh to economically liberate the copper minerals from the gangue although a clean rougher tailing can often be achieved at 65mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate thus some form of regrinding is necessary

Copper concentrators typically treat up to 100 000 t of ore per day they are located directly at the mines to achieve low transport costs the copper recovery efficiency is over 90 about 95 of the ore input goes into the tailings which are stored in large dams near the mine and are used for water recycling to the flotation stages

The finer an ore is ground the greater the energy that is required so it makes sense to fine grind only those particles that need fine grinding complete liberation is not required for rougher flotation only sufficient liberation to release enough gangue from the valuable mineral to get a high recovery
