Diamond Recovery Methods - News from All Diamond

Mar 30, 2016  Crushing . Since kimberlite is formed underground, it is a relatively hard rock, similar to granite. The first step to finding the ‘needle in a haystack’ , is crushing the kimberlite ore. This has to be done in a controlled way in order to avoid breaking or damaging the s trapped inside.

Kimberlite rock Britannica

Kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains s in its rock matrix. It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass). It is a mica peridotite, and its most abundant mineral constituent is olivine.

kimberlite is an unwanted effect in the normal processing route, a novel processing route may take advantage of this. Instead of crushing the kimberlite rock, the kimberlite can simply be soaked in water (with appropriate added salts), using the internal forces within the kimberlite to break it apart. this would have two notable advantages.
