Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

How Underground Mining Works | HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Significant Impacts Of Iron Smelting Environmental ...

The development of the iron smelting plants in the area will create a large number of jobs for the local and the regional population and he people will be involved both directly and indirectly. According to the plan each plant will employ 200 workers from the village and specialized training will be given.

TMT Bars Manufacturing Process - JSW Neosteel

Coke, ore and sinter are fed, or 'charged', into the top of the blast furnace, together with limestone. A hot air blast is injected through nozzles in the base of the furnace. This causes reduction of iron ore and the iron in the ore and sinter is melted out to form a pool of molten metal in …
