Iron ore comes in a variety of forms and looks like rock. It is a mixture of iron, oxygen and other elements, mixed in with sands and clays. Image, right: ore being mined from bell pits at Wilsontown. To make a useable metal, an ironworks has to get rid of the unwanted components of this mixture and keep as much of the iron as possible ...

The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron. The reaction between air and the fuel generates carbon monoxide. This gas reduces the iron (III) oxide in the ore to iron. Refining iron. The metal that leaves the Blast Furnace contains between 4% and 5% of carbon.

Iron Ore Handling Procedures Enhance Export Quality James E. Everett Published Online: 1 Dec 1996 https://// Abstract Iron ore is a major Australian export into a highly competitive market. Customers feed the iron ore into blast furnaces that are tuned to ore of particular composition.
A good indicator during the load is the presence of splatter marks of iron ore filings on the bulkheads. If splatter marks are evident, they should be taken very seriously as an indication that the moisture content is above the TML and the flow moisture point. If the Master is in any doubt, he should contact the owners and the P&I Club ...
The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way. A third group of iron-making techniques classed as smelting ...

This may have weighed up to 5 kilograms (11 pounds) and consisted of almost pure iron with some entrapped slag and pieces of charcoal. The manufacture of iron artifacts then required a shaping operation, which involved heating blooms in a fire and hammering the red-hot metal to produce the desired objects.
concentrates of iron are produced by either: the dry method, in which high grade ore is crushed to remove waste material, leaving a low moisture content in the powdered ore. Iron concentrates obtained by the dry method are susceptible to spontaneous combustion because of the air already trapped within the concentrate during the crushing process.

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). 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.
Step 1 - The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% - % impurities such as carbon which in turn make the metal brittle ...

For an annual production of 20 million tons of iron, which would represent about 40% of the current United States production rate, the flash ironmaking process would require TCF/year (trillion cubic feet per year) of natural gas. This represents less than % of the total United States consumption rate ( TCF/year) [ 64 ].
