DIAMOND FORMATION AND SEPARATION
The formation of diamonds occurred deep within the earth about 55 million years ago. The intense heat and pressure of volcanic Kimberlite magma carried diamond ore closer to the surface, forming Kimberlite pipes. Of the 5,000 Kimberlite pipes found on earth only 23 of them are rich enough with diamonds to be mined.
Separating diamonds from Kimberlite host rock does not require chemicals. Diamond-bearing ore is reduced in size, mixed with water and crushed. Magnetic sand is added to enhance mineral separation. The diamonds are separated further with the use of x-rays, photo-electric sensors and air blasts.
