According to some reports, the De Beers group expects revenue growth, since its equipment for mass sifting of clay and various technological innovations will help to extract diamonds in the deep waters off the coast of Namibia.
Reuters reports that the "green machine", controlled remotely from a mining vessel called Mafuta, extracts diamonds, sifting sand and clay at a depth of 100 m or more under water.
The Mafuta vessel is the largest mining vessel of the operator Debmarine Namibia, a joint venture of the government of Namibia and De Beers, in which the partners own equal shares.
"Ten years ago, a sand sifting machine could develop areas from 200 to 250 square meters. m per hour, and now, according to our estimates, its capacity can reach 1,000 sq. m. m per hour, "said De Beers Marine CEO Domingos Valbom. "This is the best way to produce marine diamonds, but it is necessary to find areas of certain geological characteristics, and for the machine to work, you need a suitable surface."
