Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
General. India has the fourth largest iron ore reserves in the world after Russia, Brazil, and Australia. As per the survey conducted by the Indian Bureau of Mines (IBM) in April 2000, India had 9919 million tonnes of recoverable reserves of haematite and 3546 million tonnes of magnetite.As good quality iron ore deposits are depleting very fast, beneficiation
Sep 18, 2019 How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
