Keywords- Low Grade Goan Iron Ore, Process Optimization, Cost of production. Iron Ore Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make ...
Dec 14, 2019018332Iron producers extract the ore from rocks that typically contain other elements like nickel. The mining process starts with digging up ore-rich rocks, which the industry crushes into smaller pieces.
The results are the products pig iron and slag. Pig iron is not suitable as a construction material but is the starting material for the production of steel. It must still be desulphurised. Steel is produced in a second step through the so-called refining process with pure oxygen. The carbon content is reduced from about 4 to a maximum of 1.5.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

Introduction of iron ore Steel slag is a by-product of the steelmaking process. It is composed of various oxides oxidized in the smelting process by impurities such as silicon, manganese, phosphorus and sulfur in pig iron and salts generated by the reaction of these oxides with solvents.
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90 of alumina refineries in the world use the Bayer ...
