Iron Ore Mining Techniques Metal Extraction

Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef

Iron ore - Wikipedia

Iron is the world's most commonly used metal—steel, of which iron ore is the key ingredient, representing almost 95% of all metal used per year. It is used primarily in structures, ships, automobiles, and machinery. Iron-rich rocks are common worldwide, but ore-grade commercial miningoperations are dominated by the countries listed in the table aside. The major constraint to economics for iron ore deposits is not necess

Iron Mining Process - Minnesota Iron
