From Raw Material to Finished Product: Unveiling the Journey of Steel
The journey begins with the acquisition of raw materials. Steel, primarily composed of iron ore, undergoes an intricate extraction process. Iron ore is mined from deposits around the world, often in the form of hematite or magnetite. These ores are then processed to extract the iron content, which serves as the foundation for steel production.
