These ships use a powerful crawler that sucks up gravel on the seabed through flexible pipes. Sometimes a large-scale drill mounted to a ship is used to excavate for diamonds. Step 3: Ore processing. Diamonds are recovered from ore in five stages: Crushing. Once diamond-bearing ore and gravel is collected, it is transported to a primary crusher.

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.

Source: Geoscience Australia. Diamonds are made of pure carbon in a crystallised form, although they often contain inclusions of other minerals and are an excellent refractor of light. Diamonds are usually clear, although they have a range of colours, such as are pink, golden or blue. Diamonds rate a 10 on the Mohs scale of hardness (from 1

Processing. Debswana introduced in-pit crushing at Jwaneng in the mid-1990s. Following secondary crushing, dense-medium cyclones separate 99% of the waste from the diamonds. Tailings from this process are recrushed and recycled. Security is a key feature of plant design, especially the materials-handling systems.

1- Crushing. The first step in kimberlite ore processing is crushing. 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

Diamond Ore Processing
Some alluvial mines can completely skip the crushing stage if the diamonds are found in sand, earth or fine gravels. Crushing is a multi-stage process of breaking the rocks into ever smaller pieces and re-circulating larger pieces until everything is the right size to enter the processing plant.
