The iron ore is predominantly mined by opencast mining throughout the country. The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays.
The molten layer that sits atop the liquid iron in a blast furnace is called slag. It is drained off and hardens into a rock-like material. I used to have a chunk of slag - it was grey and had a glassy appearance.

Iron, which includes its refined product steel, is the most widely used of all the metals. Iron and steel products are used in many construction and industrial applications, such as appliances, bridges, buildings, containers, highways, machinery, tools, and vehicles.
SLAG is an industrial waste product – there is no standards about the quality of it. What is in it depends on what was the raw material used for the production of iron – e.g. scrape metal, iron ore,.. Orcem claims that absolutely none of the Orcem's material or products are toxic.
Aug 18, 2012· Iron ore - Wikipedia, the free encyclopedia. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey ... what are the byproducts of mining copper - Gold Ore Crusher
use of iron ore waste products Steel is a malleable alloy of iron, carbon (and alloying elements) and also the main end product of iron ore treatmentore, siderite, limestone and iron-bearing waste products rich in iron (like scale, etc) is used, Get Price; Blast furnace Wikipedia.
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being ...

For iron ore mines, the stripping ratio ranges around 2-2.5.15 This means that for every tonne of iron ore produced, double the quantity of waste is generated. In 2003-04 itself, SAIL generated 4.76 million tonnes of overburden and rejects from its 12 mines in the country.16
46) Limestone is added to the iron producing mixture in a furnace to A) add carbon to the mixture. B) provide an additional reducing agent to extract all of the iron from the ore. C) combine with silicates to remove impurities in the form of a slag. D) produce a more corrosion resistant iron.

Iron can also be converted into steel, one of the most popular finished products of Iron ore with 98% of all iron ore mined going to its production. Iron ore is primarily mined and refined through a process called smelting. Smelting is a heating process in which the Iron ore is heated along with coke (charcoal) and limestone in a blast furnace ...
Waste rock can be processed to a desired gradation by crushing and sizing, like any other source of aggregate. The hardness of the waste rock is determined by the rock type. For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense.
Figure 1 shows the process flow of this approach carried out in an ore dressing plant of iron mine. In this flowsheet, there are four products excepting iron concentrate. They are waste rock, coarse tailings, fine tailings and muddy tailings.

Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
