Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. Primary Crusher
The optimization process aims to minimize the unit cost (€/m3) of the operations that integrate the primary blast, secondary and crushing rock, taking into account preestablished criteria to obtain a lower global cost per m3. In this way, a pseudooptimal geometry of the blast was generated through the resolution of the model by the Solver Excel tool.
