Birla Corpn, the flagship company of the M P Birla group, will invest around Rs 950 crore to set up new units in four states.
The company will set up three grinding-cum-blending units in Madhya Pradesh, one grinding unit in Bihar, one blending unit in Uttar Pradesh and another in Jharkhand, which will have a combined capacity of 4.5 million tonne.
Also, in the first week of August, the company started its mechanical mining at its Chanderia mine in Rajasthan after an interim order by the Supreme Court on July 29. Due to the mine's proximity to Chittorgarh Fort - a heritage structure - the Jodhpur High Court had banned mining at the site in August 2011.
