Sesa Goa Iron Ore, a Vedanta Group company, is engaged in the exploration, mining, and processing of iron ore. The company was founded in 1954, as Scambi Economic SA Goa. Since then, it has grown to be one of the country's top low-cost producers of iron ore. During 1991-1995, it diversified into pig iron and metallurgical coke manufacturing.
Similarly, recycling is used in most steel production. According to the U.S. Geological Survey (USGS), 40% of U.S. steel production in 2011 came from basic oxygen furnaces (BOF), whose inputs are almost 80% pig iron (molten iron), whereas 60% of production came from electric arc furnaces (EAF), which use more than 90% scrap.
PITTSBURGH-- (BUSINESS WIRE)-- United States Steel Corporation (NYSE: X) ("U. S. Steel") announced today it would expand its low-cost iron ore competitive advantage and increase its self-sufficiency by supplying domestic feedstock to its growing fleet of electric arc furnaces (EAFs).

Iron and steel manufacturing in the United States produces 7% of industrial emissions. Steelmaking is energy- and emissions-intensive, requiring high process temperatures and a source of carbon to drive reactions. Generating heat and the chemical reactions that occur during steelmaking processes both produce significant emissions.
The Steel Manufacturing Process. The steel production process is a multi-faceted journey that begins with extracting and processing iron ore, a primary raw material essential to steel making. Iron ore undergoes a series of refining steps to extract the iron content, culminating in the creation of molten iron. This molten iron is then subjected ...
