Jindal Steel and Power, India’s biggest producer of the alloy by market value, plans to spend $300 million in developing new and existing mines in Africa. The move is part of the company’s strategy to source coal assets abroad to meet raw material demand of its steel and power plants at home. Jindal Africa, the company’s Africa subsidiary, would invest $250 million in developing a coalmine in Mozambique’s coal-rich Moatize region, Ashish Kumar, CEO of Jindal Africa, told ET on the sidelines of an international mining meet.
