Iron-ore mining methods vary by the type of ore being mined. There are four main types of iron-ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits. Iron ores. magnetite (Fe 3 O 4, 72.4% Fe) hematite (Fe 2 O 3, 69.9% Fe)

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall.

Jun 14, 2013· Surface mining consists of stripping soil and vegetation away and possibly a limited amount of rock and then removing ore in large quantities. Conversely, subsurface mining involves sinking a mineshaft and digging tunnels to reach a deposit at depth. These two broad categories encompass almost all mining techniques and will be discussed in detail.

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
