Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing

Copper mining usually is processed in very large, open pits. The process of mining requires the rock to be loosened by blasting. The process begins by drilling the rock to place the explosive. The blasted rock is then scooped up into large dump trucks that haul it to crushing plant. Zenith is a supplier and manufacturer of copper mining equipment
