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. Small, low-capacity mines have rapidly disappeared.

Methods and tools of indigenous mining Flashcards
Stone hammers and pounders were used to break large ore. Iron chisels were used to plug the smaller ore. These were pointed at both ends with one end fixed in a wooden handle. Stone wedges were used to enlarge ancient mines or trenches. Fire was used to crack the rock which was then cooled rapidly with water.
