4.1 Process Overview 4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions.
Mining is the process by which naturally-formed materials are extracted from the earth. These materials include gold, iron ore, coal, lead, silver, lithium (also from salt deserts), etc. Quarrying involves extracting materials from the surface of the earth.
