Mining and Mineral Processing 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 …

Open-cut mining is a process of resource extraction where it is dug up from the surface. Also known as open-pit mining or open-cast mining, it is the most common form of extraction for minerals or coal in Australia. The technique of open-cut mining is used when the deposits are close enough to the surface to be readily extracted.
