Silica based Product Identified for Production from Kimberlite Tailing

Abstract

National Mineral Development Corporation is involved in diamond mining in the country & Kimberlite produce as a mines waste during kimberlite mining .N M D C is producing around 0.9 million tones of Kimberlite per year in Panna. With estimated life of 20 years for Panna mines , it is pertinent to look for commercial application of kimber-lite . Around 3-4 million tones of Kimberlite is already available from Panna mines accumulated during previous mining . Due to the fact that Kimberlite / Diamond ratio is 100 tones of kimberlite per 10 carat of Diamond produ-ced, there is a need to look for development of multi — product which are of bulk usage from the Kimberlite. Technological option for Eco- friendly & Economically Efficient Utilization of Kimberlite needed and in view of their wide application, also bulk usage, the following three products were identified to be developed from Kimberlite.
