Various crushing techniques are used in the diamond industry. As is common with all mineral treatment plants, crushing plays a role not only in reducing the ore to a size suitable for down-stream processing, but more importantly in liberation of the sought after mineral.
Get QuoteThe ore is then crushed to progressively smaller pieces, removing the finer material. Diamonds are separated from the crushed ore by non-chemical, density-based methods to create a diamond-rich heavy-mineral concentrate (figure 19).

Get QuoteMost 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.
Get QuoteMineral 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.
