  • Ocean Mining The Canadian Encyclopedia

    Ocean MiningConventional Underground MiningDeep-Ocean ExplorationSeveral types of valuable mineraldeposits exist under the oceans and other large bodies of water. Where water is shallow, placer deposits can be recovered by large dredges (eg, tin minerals off the coasts of Java and Borneo). Where deposits lie in shallow water near the shore, dams may be built around sections of the shoreline and the areas pumped out so that shovels or scrapers can be used to excavate the material. Diamond-bearing gravels are mined in this way along the coast of southwestern Africa.

    A Comprehensive Breakdown of The Mining Process and All Its intricacies.Prospecting/SurveyingExplorationMine-Site Design/PlanningDevelopmentProductionClosure/ReclamationThe mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economyand the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have broken down the mining process into six comprehensive steps.See more on thebossmagazine

    OverviewBrief historyResources minedExtraction methodsEnvironmental impactsControversySee alsoExternal links

    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 (4,600 to 12,100 ft) 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 the surface to be pr

  • Mining the Ocean Floor with Robots West Coast Placer

    DepositsMiningExplorationThe ocean also has types of deposits that we can’t find on land. One special mineral deposit is called Polymetallic Nodules. These are concretions of metallic minerals that occur under the ocean. The nodules grow sort of like stalactites do in a cave, over time layers of metallic minerals precipitate out of seawater and add to the nodule. The growth of nodules is one of the slowest known geological processes taking place at a rate of one centimetre over several million years. Polymetallic nodules are roughly the
  • The Mining Process – Waihi Gold

    A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

  • The Voisey's Bay Mine

    DiscoveryNegotiationsMining and ProcessingIn 1993, the diamond prospectors Al Chislett and Chris Verbiski inadvertently discovered large nickel, copper, and cobalt deposits at Voisey's Bay while under contract with Diamond Resources. Their find proved to be one of the most significant nickel discoveries of the late-20th century and attracted attention from international mining companies, including Canadian-owned Falconbridge and Inco (which later changed its name to Vale Inco after merging with Brazilian-owned Companhia Vale do Rio Doce in 200

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing ...
