Diamond Mining Process - Least glamourous but essential

The diamond mining process is as old as the discovery of diamonds in India…this was approximately in the 9th Century BC. The exact origin of diamonds is still something of a mystery. Its know that diamonds were created by nature more than 3 billion years ago.

How Are Diamonds Mined And Extracted From the Ground

In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the post-processing is shorter and is a less resource-consuming task as diamonds are identified in situ of the work area.

Drilling - Wikipedia

Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point.The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is ...
