NATURAL RESOURCES SUSTAINABILITY: IRON ORE MINING .

In some low grade iron ores, intensive grinding and separation (as well as sintering or pelletising) must be performed to release the mineral. Grinding consumes a significant amount of energy, and this issue is clearly exposed in the EII index. Energy consumption issues due to grinding are a common problem for magnetite.

Iron ore - Wikipedia

This determines the energy inputs required to run a milling operation. Mining of banded iron formations involves coarse crushing and screening, followed by rough crushing and fine grinding to comminute the ore to the point where the crystallized magnetite and quartz are fine enough that the quartz is.
