Iron processing: Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting.
Back — The roof or upper part in any underground mining cavity. Backfill — Mine waste or rock used to support the roof after coal removal. Barren — Said of rock or vein material containing no minerals of value, and of strata without coal, or containing coal in seams too thin to be workable.
Iron Ore Agglomeration Processes and their Historical Development. There are four types of agglomerating processes which have been developed (Fig 1).
Origins & development of the villages, including iron ore mining & Furness Railway.
The Sintering Process of Iron Ore Fines Sintering plants are normally associated with the production of hot metal in blast furnaces in integrated steel pants.
A Agglomerating Processes. Fine particles of limestone (flux) and iron ore are difficult to handle and transport because of dusting and decomposition.
There are several methods by which a limited supply of hot metal could be stretched by increasing scrap utilization. Process optimization of current oxygen steelmaking technologies will result in small improvements in yield by reducing both the iron content and total volume of slag produced.
Types of surface mining . Strip mining: This process involves the method of extracting the mineral by removing soil and rock which are deposited on the surface.Coal and Lignite are the two principle minerals that are extracted through this method.

Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries.
then reacts with the iron ore to form carbon dioxide and pure iron. Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace.
