Additional separation of the denser material occurs by centrifuge in “cyclones” that swirl the mixture at low and high speeds, forcing the diamonds and other dense minerals to the walls and then out the bottom of the cyclone. Waste water rises at the center of the cyclones and is sucked out and screened to remove waste particles. The DMS process results in a concentrate that generally ...
Despite cyclone technology being well established throughout various process industries, performance modelling of this technology still enjoys considerable attention, a fact that is testament to the poorly understood nature of its operation. De Beers is heavily dependent upon DMS technology, as this forms the primary bulk reduction step in the diamond winning process. A typical industrial DMS ...

discharge hopper or speeding up the cyclone feed pump) will also change the pressure. Within limits, an increase in operating pressure will cause the cut point to drop (finer overflow). This is because the centrifugal force on the particles is increased, forcing more fine particles to the cyclone wall and hence reporting to the underflow ...

The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE. Unlike the rake and spiral classifiers, the overflow ...

TOMRA Sorting diamond recovery solutions replace the conventional concentration and recovery stages such as Dense Media Separation (DMS) and X-Ray Luminescence (XRL) sorting in a diamond recovery process. Advanced X-Ray transmission technology (XRT) reliably detects all diamonds including coated, low-luminescent and Type II diamonds.

Diamond processing / diamond recovery involves the separation of diamonds and other minerals from diamond bearing material. There are different methods when it comes to diamond recovery, one of which requires the use of a DMS plant. A DMS plant, or Dense Media Separation Plant, involves a process that uses the principle of gravity to separate materials with different densities. Dense Media ...
This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands. Producing areas in Canada, South Africa ...
Apart from Alrosa, other important diamond mining companies include BHP Billiton, which is the world's largest mining company; Rio Tinto Group, the owner of the Argyle (100%), Diavik (60%), and Murowa (78%) diamond mines; and Petra Diamonds, the owner of several major diamond mines in Africa.

Diamond Mining Methods Diamond Museum Cape Town. Stage 3 Cyclonic separation plant During this stage the bearing ore is mixed with a solution of ferrosilicon powder and water, which is measured to a specific relative density. This solution is fed into a cyclone, which tumbles the material and forces a separation. Materials with a high density ...
Marine mining involves extracting diamonds from the seabed, hundreds of meters under water. 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
