Open Pit Mining Techniques|Surface Mines|Rock or Mineral
Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut 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 extractive methods that need tunneling into the earth.

Iron Ore Processing
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

Iron Ore Mining | Techniques | Metal Extraction
MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.

The Step-by-Step Process of Producing Iron from Iron Ore
Now, first of all, pure iron is rarely available (except if one or two meteorites crash). It has to be derived from iron ore that occurs near the surface when mining. Then the iron derived after a long processing in the blast furnace is handed over to the iron and steel industry to make a huge amount of useful materials.

Iron ore
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, led after World War II to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron ore mining methods vary by the type of ore being mined.

Dry Iron Ore Beneficiation | Iron Ore Separation
Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.
