Automation and Robotics in Mining and Mineral Processing
All mining operations have a least some limited mineral processing available on site. Usually the sophistication of the complex is determined by unit process operations needed to make the product, or distribution and transportation costs (Fig. 57.1). The mineral extraction process can occur using many potential mining methods.

The particle size is reduced in each compression, resulting into finer particle size distribution as the material passes through the chamber. The CSS will affect the product size significantly, and because the same feed was used in both simulations, the reduction of the particle size in Fig. 10 is limited due to the larger CSS.
