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
Buffalo Head Hills kimberlite field in mudstones that are interbedded with some of the kimberlite deposits are consistent with the Late Cretaceous age. The BHH kimberlite pipes cover areas ranging from one to . They represent maar-style volcanoes which have a vertical-walled volcanic crater of explosive origin, surrounded by a low rim of ejecta and filled with water. Pyroclastic fall and surge are the two volcanic mechanisms of deposition. There are also deposits formed by hydraulic reworking of kimberlite from tephra cones and/or extra-crater fall and surge deposits. The pyroclastic fall deposits are poorly sorted and massive, while the surge deposits are better sorted, fine
