Iron Ore Mining | Techniques | Metal Extraction

MINING AND PROCESSING: 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 ore is also being done manually on a small scale.

Mining Methods 101: How the Metals We Need Are Extracted ...

06-07-2016 · Processing. Once the ores have been excavated, the metals themselves must then be extracted from the ore, a process that depends on the metals’ reactivity, according to BBC. Highly reactive metals such as aluminum, for example, can be isolated using an electric current in a technique known as electrolysis. Less reactive metals like iron can ...
