Most natural diamonds are formed in Earth’s lithospheric mantle; however, the exact mechanisms behind their genesis remain debated. Given the occurrence of electrochemical processes in Earth’s mantle and the high electrical conductivity of mantle melts and fluids, we have developed a model whereby localized electric fields play a central role in diamond formation.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Diamonds are usually clear, although they have a range of colours, such as are pink, golden or blue. Diamonds rate a 10 on the Mohs scale of hardness (from 1 - 10). This makes diamond the hardest natural mineral on Earth. Diamond has a very high melting point of 4000 C which is 2.5 times hotter than the melting point of steel.
