Deepsea Mining In Namibia
Namibia is one of the first countries that issued Mining in Namibia, mining licences regarding deep sea mining. studies that took place in 1970s discovered considerable amounts of phosphate deposits. The significance of seabed mining in Namibia's blue economy is highlighted by the country's status as a "phosphate factory". This is due to the exceptional upwellings of the Benguela Current ecosystem, a transboundary ocean current that spans from South Africa in the south to Angola in the north, passing through Namibia. Those deposits were found in depths between 180 and 300 meters below the sea level. In 2011 the Government of Namibia, Namibian government issued licences regarding the exploitation of the seabed phosphate resources after the necessary Environmental impact assessment, Environmental Impact Assessments (EIAs). The action plan that stood out was that of Namibian Marine Phosphates (NMP), a joint venture formed in 2008 between two Australian-based companies, Minemakers and U ...

Manganese
Manganese is a chemical element; it has Symbol (chemistry), symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent, as a rubber additive, and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese is commonly found in labo ...

Underwater Mining
Seabed mining, also known as seafloor mining is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains. The increased requirement for minerals and metals used in the technology sector has led to a renewed interest in the mining of seabed mineral resources, including massive polymetallic sulfide deposits around hydrothermal vents, cobalt-rich crusts on the sides of seamounts and fields of manganese nodules on the abyssal plains. While the seabed provides a high concentration of valuable minerals, there is an unknown risk of ecological damage on marine species because of a lack of data. Resources The varied geological and biological processes occurring in the ocean produce economically viable concentrations of a range of minerals, notably in the vicinity of hydrothermal ven ...

Deep Sea Mining
Deep sea mining is the extraction of minerals from the seabed of the deep sea. The main ores of commercial interest are polymetallic nodules, which are found at depths of primarily on the abyssal plain. The Clarion–Clipperton zone (CCZ) alone contains over 21 billion metric tons of these nodules, with minerals such as copper, nickel, cobalt and manganese making up roughly 30% of their weight. It is estimated that the global ocean floor holds more than 120 million tons of cobalt, five times the amount found in terrestrial reserves. , only exploratory licenses have been issued, with no commercial-scale deep sea mining operations yet. The International Seabed Authority (ISA) regulates all mineral-related activities in international waters and has granted 31 exploration licenses so far: 19 for polymetallic nodules, mostly in the CCZ; 7 for polymetallic sulphides in mid-ocean ridges; and 5 for cobalt-rich crusts in the Western Pacific Ocean. There is a push for deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Beers
The De Beers Group is a South African–British corporation that specializes in the diamond industry, including mining, exploitation, retail, inscription, grading, trading and industrial diamond manufacturing. The company is active in open-pit, underground, large-scale alluvial and coastal mining. It operates in 35 countries, with mining taking place in Botswana, Namibia, South Africa, and Canada. It also has an artisanal mining business, Gemfair, which operates in Sierra Leone. From its inception in 1888 until the start of the 21st century, De Beers controlled 80% to 85% of rough diamond distribution and was considered a monopoly. By 2000, the company's control of the world diamond supply decreased to 63%. The company was founded in 1888 by British businessman Cecil Rhodes, who was financed by the South African diamond magnate Alfred Beit and the London-based N M Rothschild & Sons bank. In 1926, Ernest Oppenheimer, a German immigrant to Britain and later South Africa who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond Mining
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) can color a diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, oran ...

Overexploitation
Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
