Chapter 3 Mining and Mineral Processing
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 …Web

Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.Web

Most iron ore mining operations use the 'open pit' method, where miners drill into the rock and blast the ore-bearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it's usually necessary to sink vertical mine shafts to access coal which is deposited in layers …Web
