view moreOpen-pit mining is the most common method used to extract iron ore. It involves using large machines to excavate large pits in the ground. The extracted iron ore is then transported to a processing plant where it is crushed and filtered to remove impurities. Strip mining Strip mining is another method used to mine iron ore.
view moreThe process of extracting iron involves a number of steps. The first step to concentrate the iron ore and remove its contents of silica. To further remove any existing impurities, a complex process takes place in a blast furnace. The charge is where materials are placed into the blast furnace. These materials are: Ore, Limestone and Coke.

view moreThe extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxidewhich is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace.
view moreThrough this process, ferrous oxide also oxidizes to ferric oxide. The blast furnace reduces iron from the iron oxide, but the complete reduction reaction requires the addition of coke and limestone to the roasted ore. After the completion of different processes in the blast furnace, molten iron flows from the bottom of the blast furnace.
view moreThe most common of the modern methods used to extract iron from its ores is coke smelting in a blast furnace. The development of this technique is largely credited to Abraham Darby, who set up his Brass and Iron Works in Shopshire in 1709, which was important in the creation of the industrial era that followed.

view moreThe primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.

view moreThe cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps: 1) Concentration The ore is crushed in jaw crushers and is broken to small pieces of about 1 inch in size. The crushed ore is concentrated by gravity separation process in which it is washed with water to remove clay, sand, etc.

view moreThe aim of ore dressing is increasing the concentration of iron in the ore by removing the unwanted impurities and improve the properties of the ore which helps in the successive stages of extraction, The ore dressing process …
view moreGravity separation process and the strong magnetic separation process are mainly adopted to the extraction of weak magnetic iron ores with coarse (2mm - 20mm) and medium particles. • Heavy media separation and jigging process are often used to deal with the extraction of weak magnetic iron ores with coarse and extra coarse (> 20mm) particles;
view moreThe most common of the modern methods used to extract iron from its ores is coke smelting in a blast furnace. The development of this technique is largely credited to Abraham Darby, who …
view moreThe ferromagnetic ore particles will then get attracted and separated from the impurities easily. Froth Floatation: This is one of the methods of extraction of metals from ores by using two mediums together. Both oil and water are used to separate impurities. It can only be done when the ore forms froth when compressed air is passed in this medium.

view moreExtracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy. The steps need the ore to be concentrated first, followed by the extraction of the metal from the …
view moreExtraction of iron is a lengthy process which commences from Concentration through calcination roasting. Water and other volatile impurities like sulfur and carbonates are removed by the process of Concentration. The concentrated ore is blended with limestone (CaCO3) and Coke and fed into a blast furnace from the top.
view moreComplete iron extraction process Mixture is smashed into tiny parts and heated into high temperature. Hot air is entered from bottom of the furnace. Heat is generated by burning coke. Also carbon monoxide gas is produced by burning coke. In the furnace, bottom and top temperatures are about 1500 0 C and 200 0 C respectively.
