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.
#0183;#32;Mining and concentrating. Although workable known reserves of rutile are diminishing, ilmenite deposits are abundant. Typical mining is by open pit. A suction bucket wheel on a floating dredge supplies a mineralrich sand to a set of screens called
Openpit mining Openpit is one of the most common mining methods used and starts from the earth''s surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
Openpit Mining Operations. Openpit mines are dug on benches that are between four and sixtymeters in size, depending on the size of machinery used to excavate. The walls of most openpit mines are dug at an angle and include steps to prevent avalanches from occurring inside the build site.
Mining. The ore is removed from the ground in either open pit or underground mines. Underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Openpit 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.

As an important raw material of iron, the magnetite plays a great role in the iron industry.
The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can be sustained. There are many advantages to the open pit mining method, namely: 1.

Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and openpit mining (see Fig. ).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.
Openpit mining. Ore is extracted from LKAB''s surface mines by means of bench mining. The method is based on mining the ore in descending levels through drilling and blasting. The thickness of the slabs, known as the bench height, is 15 metres, and the slabs are worked downwards.
Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from
The Mining Process. 1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
