Diamond Pipe Mining – Open Ground/Underground. The Mir open-pit mine (“World” or “Peace”) in Russian city, Mirny. Before any actual mining even takes place, prospectors need to locate the diamond
There are a limited number of commercially available diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply. Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action.
Diamond mining is generally less harmful to the environment than other types of mining, such as gold mining, because it does not make use of toxic chemicals. Despite serious environmental risks, effective regulation and proper planning can minimize diamond mining’s environmental impact. The Canadian Arctic is a very fragile ecosystem, but it is heavily regulated to protect the surroundings ...
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

Answering Mining's Big Questions ... Barrick Gold has ownership in seven of the 20 largest gold mines on the globe based on annual output.
Trucks with 250 tonne payloads and tyres twice as tall as an average man carry diamond-rich kimberlite from the mines to be processed, and we train a workforce to run them. Off the Namibian coast, we recover diamonds from the ocean floor using advanced technology on vessels that are virtually floating mines.
De Beers has built a prestigious reputation over the years, derived primarily from one attribute: quality diamonds. The company, which has been the leader in diamonds for more than 100 years, has notoriously remained silent about its exploration tacticsuntil now. De Beers recently opened up about its exploration strategies and how the ...

Without diamond mining there wouldn’t be diamonds so we should at least know some basic facts about 4 commonly used types of diamond mining based on mining techniques: open pit mining, hard-rock mining, alluvial mining, and the marine diamond mining as the latest technique, all of which leave damaging effects on the earth, sometimes irreversible. As mining moves deeper into the earth and ...

Processing Methods Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are Rotary Pan plants and Dense Media Separation (DMS). Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery.
Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds.
Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites. By withdrawing a small diameter core of rock from the orebody, geologists can analyse the core by chemical assay and conduct petrologic, structural and mineralogical studies of
In addition, as more easily minable deposits are depleted, mining technology and equipment and mining systems for extracting problematic deposits will have to be developed. Surface Mining. Surface mining is a generic term describing several methods of mining mineral deposits from the surface, which entails removing the vegetation, top soil, and rock (called overburden materials) above the ...
Alluvial diamond mining is the term used to describe the process through which diamonds are recovered from such deposits of sand, gravel and clay. Large concentrations of alluvial diamond deposits are mined on an industrial basis. However, ...
