Working with natural stone, however, involves different initial steps than working with manufactured stone. Granite and other natural stones are quarried and cut into large stone slabs where exposure to crystalline silica dust is likely. These slabs are further cut to countertop sizes at the quarries or at stone finishing shops.

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.
