ALLUVIAL DIAMOND MINING. Lucapa and its Angolan partners Endiama and Rosas amp; Petalas commenced commercial alluvial diamond mining operations at Lulo in January 2015, with mining company Sociedade Mineira Do Lulo (SML) (Lucapa 40% owner and operator) formally incorporated in May 2016. To date, Lulo has achieved gross revenues of ~US150 million at an average sale price of
The earliest form of marine mining entailed shore diving, where a swimmer would collect diamond bearing gravel from the shallow seabed. Today technology has evolved to specialised ships that mine for diamonds deep out at sea. These specialised ships use a powerful crawler that sucks gravel on the seabed up through flexible hoses/pipes. Alternatively, they use a large scale drill mounted to the
Deep sea mining is a mineral retrieval process that takes place on the 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 oceans surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper
Oct 15, 2009#0183;#32;Contrary to the picture conjured above; the mining is actually carried out with huge vacuum pumps, tubes and ROVs. There are two (edit: well, actually three) forms of offshore diamond mining, horizontal mining and vertical mining. The most common form is horizontal mining. In this form, an ROV crawls across the seabed, equipped with sensors, suction tubes and equipment to sort
The equipment ranges from heavy duty / high capacity primary scalping screens to diamond recovery feeders. The large primary scalping screens (the largest operational on sea going processing plants) have been meticulously designed and tailormade for this specific application and have been designed using the latest finite element and strain gauge techniques.

This is the final recovery equipment used to sort your diamonds from the screened gravel of the small to medium sized operation. There are two types of jigs: Plietz jig. Requires the gravel to be presorted in fractions that vary no more than 45mm in size. Effective with gravel size up to 16mm.
In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the postprocessing is shorter and is a less resourceconsuming task as diamonds are identified in situ of the work area. Offshore Marine Diamond Mining.
