Deep sea mining - Wikipedia

Deep sea mining is a mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to ...

Deep Lead Mining Plant - Concept - Electronic Encyclopedia ...

Deep Lead Mining Plant. As large deep lead mines developed, simple gold recovery plant constructed on the surface was not efficient in treating large volumes of gravels. Efficiency was gained by treating the gravels high in the air, after which it was simply dumped below, rather than carted away to make way for more treated material.

Brine mining - Wikipedia

Brine mining is the extraction of useful materials which are naturally dissolved in brine. The brine may be seawater, other surface water, groundwater, or hyper-saline solutions from several industries. It differs from solution mining or in-situ leaching in that those methods inject water or chemicals to dissolve materials which are in a solid state; in brine mining, the materials are already dissolved. Brines are important sources of common salt, calcium, iodine, lithium, magnesium, potassium,
