Kimberlite tailings doubtful at best that it could ever be used as a construction material. In fact kimberlite exposed to water or air will alter to serpentine soil with very fine particles extremely fast. Some mines use this characteristic and stockpile kimberlite ore in outside pits and after a couple of years it can then be processed without any crushing hence better preserving the diamonds it contains. New process is described for the preparation of free flowing hydrated amorphous silica from kimberlite tailing. The process comprises treating of kimberlite with acid, further reacting it with alkali solution to obtain soluble metal silicate
Kimberlite the extreme magma composition that it reflects in terms of low silica content and high levels of incompatible trace-element enrichment make an understanding of kimberlite petrogenesis important. In this regard, the study of kimberlite has the potential to provide information about the composition of the deep mantle and melting processes occurring at or near the interface between the cratonic continental lithosphere and the underlying convecting asthenospheric mantle. Many kimberlite structures are emplaced as carrot-shaped, vertical intrusions termed "pipes". This classic carrot shape is formed due to a complex intrusive process of kimberlitic magma, which inherits a large proportion of CO
