Without diamond grit (bort or boart as it is known) much of the world’s modern manufacturing would be made far more difficult than it is While diamond mining has been taking in place in South Africa for almost a century and a half, the country’s diamond sector is far from reaching the end of its life
Diamond Geology: Formation and Types of Diamond Deposits Formation in the Earth Diamond is a polymorph form of carbonThe other form is graphite For carbon to turn into diamond, 3 factors are needed: time, very high temperature (around 1,00000 degrees) and very high pressure above 30 kilobars (kb) The Pressure and Temperature conditions within the earth, are known as geotherms

Description The Williamson diamond mine is a large open pit mine currently about 90 meters (300 ft) deep Diamond mining operations at the Williamson diamond mine are composed of four distinct activities: mining of the pit, re-treatment of tailings to recover missed diamonds, and gravel mining both on the property and adjacent to the property where gravel has been alluvially deposited
Diamond Geology Page 7 debeersgroup Alluvial deposits may become lithified to form solid rock and these are commonly known as palaeo-placers The Witwatersrand gold deposits are an example, and in fact they have produced minor quantities of diamond along with other by-products In
The geology of Diamonds consist of crystalline carbon although a significant proportion of diamonds are derived from placid deposits ie hosted in sediments, placid’s are secondary deposits and all diamonds were at one time or another hosted by kimberlite igneous rocks The name Kimberlite comes from the town of Kimberley which grew up around the prolific diamond mines in northern South Africa
