open pit mining of iron ore

Open Pit Mining - an overview ScienceDirect Topics

4.2 Open-pit mining. Open-pit mining is probably most advanced because of developments in mining low-grade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow low-cost removal of most of the resource.

Mining of Iron Ores – IspatGuru

2014-3-14  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

Iron ore extraction techniques - ScienceDirect

2015-1-1  Open pit mining of iron ore is fundamentally simple when compared to underground mining. While ore grades have to be maintained at high levels in order to satisfy the market, commercial advantage is gained by the application of high-capacity modern mining equipment, but volumes have to be high and costs so low to remain competitive.

Open-Pit Mining Definition Anglo American

Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth.
