Rotary rigs are larger and faster than cable tool rigs and can also drill to greater depths, yield a smoother well bore, and diminish the time water sands are exposed to the drilling process. Cable tool rigs are sometimes favored when there are no pressing time constraints and the operator wishes to save money. Their use, however, is restricted ...
Processing of diamond ores begins with crushing. Typically, an ore is crushed initially to below 250 mm by means of a gyratory crusher and then to 75 mm using a cone crusher. The final stage of crushing is done by means of a high-pressure roller mill to further reduce the size below 25 mm. The incremental size reduction is helpful for ...

After hundreds of years of scientific advancements, diamond mining has now become an incredibly skilled process, enabling the diamond miner to extract precious stones without risks of damaging them.
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. When the diamond-rich depth is reached, the raw ...
