Marine diamond mining in Namibia occurs within the Atlantic Ocean's Benguela upwelling system, a biologically productive system that supports a high abundance of marine organisms; therefore, any effects on the ecosystem must be carefully considered. Any operator must comply with the provisions of the Environmental …
Ocean Mining, also known as Deep-Sea Mining, is the process of retrieving valuable metals and rare earth minerals from the ocean floor. Speculation about ocean mining dates back to the 1960s, when geologists of the day suggested that metals found in naturally occurring seabed deposits could be harvested to meet the rising demands of a ...
The last half century has seen a massive shift in geological thinking, and technological innovation and developments, in all facets of diamond exploration, mining, processing, recovery ...

MARINE MINING. involves utilizing special mining ships to harvest diamonds from the ocean floor. Vertical diamond mining employs a huge, ship …
Marine Mining. Marine mining is similar to alluvial mining in that it is mining gravel and sediment in bodies of water. However, marine mining takes place in the ocean on the seafloor. Earlier forms of marine mining had divers going out to sea to collect gravel containing diamonds and bringing back to land. Today, this process is done by …
Marine diamond mining takes place primarily along the 1,400 km stretch of coastline of southern Namibia and northwestern South Africa. Namibia has the richest known...
Marine Diamond Mining. This method of mining for diamonds, which is among the most recent mining innovations, attaches crawlers to ships to collect seabed gravel that would subsequently be processed. Naturally, this only happens in nations with access to water. 4. Alluvial (Artisanal) Mining
Marine diamond mining is much the same process but takes place in coastal waters and involves a ship with specialized technology that either sucks up gravel on the seabed …
Marine mining. In Marine mining, diamonds are extracted from the sea bed deep underwater. Ships with specialised technology and powerful crawlers are used to get the diamond from the deep underwater for this specific purpose of diamond mining. These crawlers pull the gravel on the seabed using flexible pipes or hoses.
Debmarine Namibia is a joint venture marine diamond prospecting and recovery company, owned in equal shares by the Government of the Republic of Namibia and De Beers Group. Debmarine Namibia began operations in January 2002 and recovers marine diamonds off the southern coast of Namibia in the Atlantic 1 mining licence area.
Our diamond exploration and mining takes place along the south-west coast, offshore in the shallow waters and inland areas of Namibia's //Karas Region. Diamonds extend into the surf zone as well as shallow marine areas and the mainland-based operations are found in the town of Oranjemund and satellite mines along the Orange River.
The 3 standard types of diamond mining include open-pit mining, hard-rock mining and alluvial mining. There's also marine diamond mining which is extremely damaging since eco-systems that haven't even been fully understood are being destroyed. Each year, over 150 million carats of diamonds are extracted from the Earth through mining.
History | Debmarine Namibia is Namibia's leading marine diamond mining company and is a recognised world leader in marine diamond exploration and mining technology.
Marine diamonds mining is a relatively new method for mining diamonds: Only since the nineteen sixties did the idea arise to draw diamonds from the seabed at sites located opposite estuaries. This type of mining is conducted through the use of huge pumps that are installed upon the mining vessel. The ship is located a few kilometers …
Marine diamond mining in Namibia occurs within the Atlantic Ocean's Benguela upwelling system, a biologically productive system that supports a high …
Diamonds are harvested from the ocean floor using remote-controlled vehicles and ships equipped with technology to separate diamonds from sediments. Ocean diamond mining poses long-term …
Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic
Diamond-bearing gravels were discovered as early as 1903 close to the Limpopo River, 35km north-east of the present mine. De Beers Group began a sampling programme in 1969 to locate the source of these alluvial diamonds. Viable kimberlite pipes were discovered in 1980. Work on the mine started in 1990 and full production was achieved …
Alluvial diamond mining remains important, and the discovery and development of several diamond pipes will make hard rock mining an important contributor to Angola's production. One mine of particular note is the Lulo Mine, owned by Lucapa Diamond Company. It is an alluvial mine that produces some of the world's largest type IIa diamonds.
It's a technology-intensive endeavor that extracts diamond-bearing gravel from the seabed, revolutionizing how diamonds are mined from marine diamond mines. Likewise, vertical diamond mining has reshaped the excavation of kimberlite pipes, extending deep into Earth's crust to retrieve gem-quality diamonds later fashioned into …
Marine diamond mining is used to retrieve diamonds deposited in marine environments. In this process, after scouting the location, large vessels with dredges remove sediment from the ocean floor. The sediment is then sorted on the ship, where the diamonds are removed and the excess sediment is then returned to the ocean floor. ...
For marine diamond mining it is especially cognitive legitimacy which has played a key role in securing the SLO status of approval. In fact, marine diamond mining is a sector strongly embedded in Namibian society (Interviewee 4, 2018; Interviewee 7, 2018; Interviewee 1, 2018).
In Namibian waters off the west coast of Southern Africa, enormous mining vessels suck diamonds from the seabed.
In 2005, marine diamond mining operations surpassed production from terrestrial deposits for the first time, making Debmarine the leading diamond miner in the country (Schneider, 2020). Mining ...
Offshore Marine Diamond Mining. Coastal ships fitted with vacuum suction tubes for marine mining. Deposits of diamonds found in marine bodies are a result of kimberlite pipe erosion. When heavy rain occurs, …
Debmarine Namibia is a joint venture marine diamond prospecting and recovery company, owned in equal shares by the Government of the Republic of Namibia and De Beers Group. …
This article presents this conceptual framework and applies it to the case of marine diamond mining in Namibia.
Marine diamond mines are divided into three types: ancient beach mines, existing beach mines, and offshore mines, and offshore mine deposits can be mined at least 200m deep. The earliest …
Deeper water and the prevailing sea conditions required the development of new, unique, marine mining equipment. The first large scale mining production of 22 kct was achieved by De Beers in 1989 with an output of 22 kct. Annual marine output from all sources now exceeds 0.6 Mct worth some US.$ 170 M, and rising to 0.7-0.8 Mct for 1998.
The marine diamond mining sector, off the southwestern coast of Namibia, is responsible for diamond production of between 1.5-million and 2-million carats a year, with about 95% of the diamonds ...
The third method, marine diamond mining, extracts diamonds from the ocean floor. While the earliest form of marine diamond mining laboriously required a swimmer to collect gravel from a shallow …
