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
Gemstone irradiation Gemstone irradiation The gemstone irradiation is a process in which a gemstone is artificially irradiated in order to enhance its optical properties. High levels of ionizing radiation can change the atomic structure of the gemstone's crystal lattice, which in turn alters the optical properties within it. As a result, the gemstone's color may be significantly altered or the visibility of its inclusions may be lessened. The process, widely practised in jewelry industry, is done in either a nuclear reactor for neutron bombardment, a particle accelerator for electron bombardment, or a gamma ray facility using the radioactive isotope cobalt-60. Irradiation has
