  • Prospecting - Wikipedia

    OverviewHistorical methodsThe gold rushesModern ProspectingSee alsoExternal links

    Prospecting is the first stage of the geological analysis (second – exploration) of a territory. It is the search for minerals, fossils, precious metals or mineral specimens, and is also known as fossicking. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to

    Coal mining - Coal mining - Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is ...

    Mineralstar Mining: Prospecting Methods. The suction dredge is a relative newcomer to the prospecting world, having only been used widely since the 1950s. The dredge is the ultimate gold-getting tool for recovery of stream-bound placer gold, because it allows the prospector to actually work gravels in the course of the active streambed.. The dredge operates by forcing high pressure water from ...

    There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

  • Mining - Wikipedia

    Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
