    14/03/2014· The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

    Iron Making Boundless World History

    In the Bessemer process, molten pig iron from the blast furnace was charged into a large crucible, and air was blown through the molten iron from below, igniting the dissolved carbon from the coke. As the carbon burned off, the melting point of the mixture increased, but the heat from the burning carbon provided the extra energy needed to keep the mixture molten. After the carbon content in

    Iron Ore Smelting Process Bright Hub Engineering

    There are two distinct categories of iron ore mining, surface mining such as open cast or strip mining and underground mining. At the surface iron ore processing plants, the iron ore is put through crushers and ball mills to break it into a uniform and more workable size and then washed with the residue going to tailings. The ore is the transported to the various smelters located locally or on

    Cast iron was too hard and brittle for most uses, but by the late eighteenth century blast-furnace improvements, the replacement of charcoal by coal and then coke, and Cort's new puddling process yielded iron of sufficient quality and quantity to supply Britain's growing industrial demands. Until then, British manufacturers had imported iron from Sweden and Russia, where cheap labor, abundant

    Iron ore mining process and iron ore mining equipments

    Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse. Common iron ore crushers are jaw crusher, cone crusher and fine jaw crusher.

    Iron Ore Smelting Process Bright Hub Engineering

    Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.

    However, new processes were adopted in the ensuing years. The first is referred to today as potting and stamping, but this was superseded by Henry Cort’s puddling process. Cort developed two significant iron manufacturing processes: rolling in 1783 and puddling in 1784. Rolling replaced hammering for consolidating wrought iron and expelling some of the dross. Rolling was 15 times faster than

    Scope of the system that was to be modelled is the material flow between mining pits (cut-backs in the deposit) and the processing plant. Mining pits and processing plant were treated as “black boxes”, meaning their behavior was only modelled on an abstract level. Significantly more detailed were the models for trucks, conveyors, crushers and stockpiles.

    Extraction is the removal of ore from the ground on a large scale by one or more of three principal methods: surface mining, underground mining, and in situ mining (extraction of ore from a deposit using chemical solutions). After the ore is removed from the ground, it is crushed so that the valuable mineral in the ore can be separated from the waste material and concentrated by flotation (a process that
