C. Secondary Crushing and Screening Coarse ore is conveyed from the coarse ore stockpile to the secondary screens. Oversize ore is sent to the secondary crushers that reduce rock size to nominal -0.25 inch and sends it off to the tertiary crushing plant. Undersized material that passes through the screen is discharged to the tertiary crushing

ore. Four general types of operation are carried out: 1. Comminution – particle size reduction by dry crushing of “run-of-mine” ore followed by grinding of dry or slurried material; 2. Sizing – the separation of particles by size, either by screening, or by classification. Classification exploits the differences in settling velocities due

Comminution | Multotec
Crushing and grinding are common comminution processes, where the main aim is the liberation and reduction of the size of the ore. Crushing techniques make use of cone, jaw or gyroscopic crushers, yet grinding techniques are more often performed by milling, such as SAG or ball milling.

11.24 Metallic Minerals Processing
The number of crushing steps necessary to reduce ore to the proper size vary with the type of ore. Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a tertiary crushing. Softer ores, such as some uranium, bauxite, and titanium/zirconium ores, require little or no crushing.

Introduction to Mineral Processing
This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a target size required for physical separation or chemical extraction are returned to the crushing or the grinding circuit. Figure 2.

sensor based ore sorting; however, other alternatives which may be cheaper and/or simpler such as gravity concentration and pre-screening should always be evaluated. Pre-concentration with an ore sorter has the added advantage that it can complement mining selectivity at the bench or stope by determining grade.
