NMDC has signed an Agreement for Collaborative Research with CSIR-IMMT, Bhubaneswar, on ‘Feasibility Studies for Preparation of Fused Magnesia from Kimberlite Tailings’. NMDC operates the only mechanised diamond mine in Southeast Asia at Panna in Madhya Pradesh. This mine produces around 10 carats of diamond (2g) per 100 tonnes of kimberlite processed, which is dumped as waste after the recovery of diamonds. Kimberlite tailings are used for the development of value-added products and are also known to be a good source of caustic magnesia.
Addressing this research gap for the best utilisation of kimberlite that is available and has accumulated over the years at Panna Diamond Mines, NMDC has initiated the Research Agreement to study the processing and preparation of fused MgO and TiO2.
NMDC is a state-controlled mineral producer of the Government of India. It is fully owned by the Government of India and is under administrative control of the Ministry of Steel.
