KIMBERLITE BASED PRODUCTS

FIELD OF THE INVENTION

In general, this invention relates to the field of material sciences. In particular, this invention pertains to production of Kimberlite based products. This invention also relates to a method of manufacturing kimberlite based products having applications in the field of agriculture. BACKGROUND AND PRIOR ART OF THE INVENTION

It is known that diamonds are formed when carbon deposits are exposed to high pressure and temperature for prolonged periods. Deep within the earth, there are regions that are at a high enough temperature and pressure that the formation of diamonds is thermo dynamically possible. Under the continental crust, diamonds from starting at depths of about 90 miles where pressure is roughly 5 giga pascals and the temperature is around 2200° Fahrenheit. Diamonds are mined in 'kimberlite pipe'. Kimberlite is an ultra potassic, ultra mafic, igneous rock composed of garnet, olivine, phlogopite, and pyroxene with a variety of other trace minerals. Kimberlite occurs in the earth's crust in vertical structures known as Kimberlite pipes. India is host to the largest known number of Proterozoic Kimberlite clan rocks.

A large amount of Kimberlite is required to produce a carat of diamond. Few tones are required to yield a carat of diamond. Large amount of Kimberlite after removal of diamond is available around the globe without any appropriate utility. Kimberlite contains magnesium, trace metals and silica in rich proportions. The present invention provide an answer for developing methods for utilization of industrial and mining wastes such as huge amount s of kimberlite after diamond extraction do not find any economical use. Therefore, present invention objective is to invent method of producing Kimberlite based fertilizers, wherein the kimberlite tailings after removal of diamonds were taken in present invention. OBJECTIVES OF THE INVENTION

Accordingly, the primary object of this invention is to kimberlite based products from Kimberlite which can be used as fertilizers and decontaminates and soil detoxification and as plant nutrient.

Another object of this invention is to develop production method of Kimberlite based fertilizer products. BRIEF DESCRIPTION OF FIGURES
