  • Mining - Prospecting and exploration | Britannica

    Mining - Mining - Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and location with respect ...

    Several magnetic proximity detection systems have been developed for mining vehicles and mobile machinery to protect nearby workers. Magnetic field generators are often used in these systems to establish magnetic fields around the equipment. A sensor worn by a .

  • Q & A: Is gold magnetic? | Department of Physics ...

    Oct 22, 2007 · Shawn - Pure gold is not magnetic. That is, it doesn't form a magnet on its own. If you put it in a magnetic field it will magnetize a tiny bit, but only so long as it's in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. There are alloys of gold, for example gold with more than about 20% of the atoms replaced by iron, which do magnetize on their own, at ...

  • Mining and Mineral Exploration - Geometrics

    Mining and Mineral Exploration Home › Solutions › Mining and Mineral Exploration 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.

  • Coal mining - Prospecting and exploration | Britannica

    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 ...

  • Mineral Gallery - The Magnetic Minerals

    The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.
