3.1 Opencast Mines Opencast mining is extraction of commercial minerals from the Earth’s surface using open-pit workings. About 60 % of metallic ores, 85 % of non-metallic ores, 100 % of non-metallics, and 35 % of coal are produced by this method. The distribution of mineral resources of the world is shown in Fig. 3.1.
