Horizontal marine diamond mining uses a crawler to suck gravel from the ocean floor to the surface via flexible pipes, while vertical diamond mining uses a large, ship-mounted drill to pull up the diamond-bearing gravel. Diamond mine locations These mining techniques occur in diamond mines all over the world.
The process of diamond ... Pit-mining is the most common way to recover diamonds. In pit mining, ... The first step in processing diamonds is comminution i.e. breaking the ore by crushing and milling.

How Are Diamonds Mined? Although your search for a natural diamond may begin with a trusted online retailer or in a velvet lined glass case, diamonds come from—or are more accurately mined from—a source much closer to earth. About one hundred miles underground, heat and pressure from the earth crystallize carbon into rough diamonds.
When the diamond-rich depth is reached, the raw material extracted from the ground is then transported to a special screening plant for further processing. There's another form of alluvial mining called artisanal mining. In essence, it is basically the same method employed by gold diggers which involves the screening and straining of mud.
A 'sky mining' facility extracts carbon dioxide from the atmosphere, which is then liquified, purified and mixed with hydrogen split from molecules of rainwater to make methane. This is inserted into a diamond mill, where the diamonds are grown in balls of plasma at around 8,000°C via chemical vapour deposition.

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
Inside these Diamond Mills we grow our Skydiamonds on a tiny seeds (which we also make) in a ball of plasma running at about 1,000 degrees Celsius – roughly the temperature of the outer layer of the sun. We power our Sky Mine and entire process with energy made from the wind and sun. Each carat of sky mined diamond takes just over 40kWh of ...
This process reduces large run-of-mine lumps into smaller pieces, making them easier to handle, and releases or liberates the diamonds to be recovered in subsequent steps. Crushing is done in stages to "gently" free the diamonds from the kimberlite rock and produce a target size, usually less than 25 mm, for further processing.

Pipe mining is like the process for mining coal underground. The "blueground" (a term used to describe the earth in which diamonds are formed) is crushed and flushed with water as it moves on conveyor belts through tubes. Once the diamond-bearing matter is washed, it is dropped onto greased belts. Diamonds stick to the grease; other matter ...
