Coarse waste rejection at this location has far greater benefits as it allows 30 of all ore to be rejected as gangue 4 valueless material without expending energy to grind it to a fine size the benefits include an energy saving of 3050 and a significant coarsening of flotation tailings.
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.

Grinding process after the normal flotation the obvious temptation is to recover the value of the tailings it must be noticed that coarse ore particle recovery implies the grinding of them to liberate ore and to get a commercialgrade product it could impact on some downstream process as thickening sand dam building.
A systematic study with dbd and a mixed collector sibx and dbd system was conducted on the coarse grind 105 m of the nussir ore sample and the results showed a synergistic interaction between the two reagents the beneficiated copper concentrate using this mixture of collectors is indeed of improved copper grade and recovery.
In several gold mills nearly 50 of the gold content of the ore is recovered in a higher grade concentrate by the introduction of a unit cell between the grinding mill and classifier facility with which coarse particles float and of the greater liberation of fine particles are presented in the diagrammatic flowsheets figures 2 3 4.

Metal recoveries are high at 96 copper and 85 gold and a coarse grind size of 210 microns is achievable the m ill feed averages 06 copper and 01gt gold native copper ores would also be able to be treated at little eva but at lower recoveries 5060 single stage crushing of rom ore two stage grinding via a primary sag.
Copper ore storage many mills store not only the coarse ore but also the fine ore in open stockpiles using ore as the side walls and drawing the live ore from the center during prolonged periods of crusher maintenance the ore walls can be bulldozed over the ore feeders to provide an uninterrupted supply of ore for milling grinding copper ore.
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 on the rougher flotation copper.
