Dry milling can provide reduced transportation costs compared to wet grinding because 50% of the gross weight is liquid in many wet slurry processes. Because the removal of the liquid from a wet grinding process involves not only another process step but also requires large amounts of energy, dry grinding can provide reduced energy costs.

The Electric Automatic Laboratory Mortar Grinder Mill Model 911MPEMG100 is used to reproducibly grind, homogenize and mix a wide range of solid materials in dry / wet or cryogenic condition.

Dry grinding has significantly lower media and liner wear than wet grinding; thus, the Fe concentration in the pulp of downstream process for the same mineral is relatively lower after dry grinding. Dry grinding produces rougher surfaces (mechanically activated centers) and more agglomerated particles than wet grinding.

Reduced grinding media wear may imply that lesser iron hydroxide precipitates build up on the surface of the mineral hence improving collector adsorption and subsequently mineral recovery. Therefore, this suggests that dry grinding could result in improved sulphide mineral recovery as compared to wet grinding.
