Without having a rising pipe between a collector which mines manganese nodules scattered around sea bottom and a mining surface ship, manganese nodules are carried a net-type or a box-type recovery ...
In coal mining regions of the state, these metals may also occur from both deep and surface mining activities. Iron and manganese often occur together in groundwater but manganese usually occurs in much lower concentrations than iron. Both iron and manganese are readily apparent in drinking water supplies.
Manganese is a mineral that is found naturally in the environment and is one of the most abundant metals on the earth's surface, in air, water, and soil. It can be found in both groundwater and surface water from natural sources or as a result of human activity such as mining and industrial discharges. Manganese is used in various industries ...

manganese processing, preparation of the ore for use in various products.. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.
Manganese Steel has self-hardening properties as a consequence of which tractors, cement mixers, rock crushers, elevators and shovel containers, as well as in the rail industry (switches and crossings) and other high-impact conditions have been used for a long time in the mining industry.
