Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth.
Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective. The method of extraction was by

General Methods of Extraction In this lesson, we will discuss the extraction of four metals Aluminium, Copper, Iron and ZincIn the periodic table, Aluminium is a metal of Group 13 and Copper, Iron and Zinc are transition metalsIn general, metals are extracted from their ore (a naturally occurring substance) Aluminium is extracted,
The eventual aim of the block caving method is that the friable ore needs no blasting and continues to fracture and break up on its own, flowing down the drawbells to the extraction level, where it is removed from the ore chute mouths with loaders and sent off for processing.
for economic extraction is called a metal ore. Economic extraction means that the cost of getting the metal out of the ore is sufficiently less than How is a Metal Extracted from its Ore? The method used to extract a metal from its ore depends on where the metal is in the reactivity series.
Iron Ore. Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. The ores are generally prosperous in iron oxides and fluctuate in color ranging from dark grey, bright yellow, deep purple, to even rusty red.
