Diamond Mining Process - Least glamourous but essential
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 is washed away. The grease is then …
How To Process Alluvial Diamond Mining - MC World
how to process alluvial diamond mining Alluvial diamond mining process. Some diamonds were released from volcanic pipes by erosion of the earth’s surfacethey were then washed away down ancient riverbeds or to coastal areas. This action created alluvial deposits from which diamonds are recovered.
ALLUVIAL DIAMOND MINING FACT SHEET
Formal alluvial mining requires a considerable amount of material (called the ‘over-burden’) to be removed first to get to the gravel bed underneath, where diamonds are found. When diamonds are found on the ocean shore or on riverbeds, the gravel is removed and then taken to a plant where it is washed and screened for diamonds.
Alluvial Diamond Mining - Gathering Diamonds On The Surface
Alluvial diamond mining is an above ground form of mining which concentrates on gathering diamonds on the surface. This is the most traditional and oldest mining method in the diamond industry, which originated hundreds of years ago in India. This method is widespread even today, mainly in Brazil and Africa.
Diamond Mining Methods | Diamond Museum Cape Town
Tunnels are constructed in two levels, one above the other with funnels built to connect the two. Mining begins on the top level by blasting ore, which falls through the funnels and collects on the second tunnel. Here, loaders collect the broken ore and bring back to the surface for processing.
How Are Diamonds Mined? There Are Actually 3 Different Methods
Meet the 3 different methods. Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds.

The diamond mining life cycle - Mining for schools
Today specialised ships mine for diamonds deep out to sea. 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
Alluvial Mining: Gold, Diamonds and Platinum | Is it ...
Alluvial mining can be a very simple process. For instance, small-scale alluvial mining that’s undertaken by individual laborers involves digging and sifting through materials such as mud, sand …
How Are Diamonds Mined And Extracted From the Ground
Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters.
Imilingo and the the future of alluvial diamond mining
Dec 11, 2018 · Imilingo Mineral Processing has made massive inroads into Africa’s alluvial diamond mining sector thanks to its unique dredging and sorting technology. Its latest technological innovation, the iDredgeXRT – which combines dredging with sensor-based sorting – will be instrumental in changing the alluvial mining game in Africa and will help ...
Processing Methods | Diamcor Mining Inc.
In a Rotary Pan plant, crushed ore, when mining kimberlite, or alluvial gravel and soil is mixed with water to create a liquid slurry called “puddle” which has a density in the 1.3 to 1.5 g/cm3 range. The mix is stirred in the pan by angled rotating “teeth”.
