Adverse Effects Of Iron Ore Open Pit Mining

Iron ore, being one of the most important industrial raw materials, is exploited and consumed in large quantities in many industries, and its usage is increasing every year 1,2.The open-pit mining method is generally preferred in mining activities due to its extensive applicability to various kinds of exposed rock, its minimum production loss and its high production rate.

Mining of Iron Ores – IspatGuru

Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally limited to float ores. Mining of reef ore is also being done manually on a small ...

Open Pit Mining - an overview ScienceDirect Topics

Large, low-grade ore deposits are usually economically attractive because it permits high recovery of the resource and allows sufficient space for large and efficient mining equipment. An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery.

Mining of Iron Ores – IspatGuru

Open pit and open cut mining are the least expensive techniques for the ore extraction. Overburden and stripping ratios are important in determining whether a deposit is to be mined. The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1

Reading: Effects of Mining Geology

After mining finishes, the mine area must undergo rehabilitation. Waste dumps are contoured to flatten them out, to further stabilise them. If the ore contains sulfides it is usually covered with a layer of clay to prevent access of rain and oxygen from the air, which can oxidise the sulfides to produce sulfuric acid, a phenomenon known as acid mine drainage.

Basics of an open pit mine - Mine Engineer.Com

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the ...
