Mineral Extraction - an overview | ScienceDirect Topics
Mineral extraction sites which include strip mines quarries and underground mines contribute to surface water and groundwater pollution erosion and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals.
