Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 5070% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...
The steel industry contributes around 8% of the world's carbon emissions and is largely (73%) reliant on blast furnace and basic oxygen furnace (BOF) technologies to separate oxygen from the iron oxides that make up iron ore and produce the strong, permanent material known as steel. Making steel involves several applications of extreme heat.

The Production of Iron. First the ore is graded and crushed and the fine. particles sintered. Sintering is the process of. converting fine particles into a continuous mass. Iron ore powder is compacted and then heated to a. temperature below the melting point of the metal. in the ore, this results in the waste being.

At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.
13. Driving Force for Sintering As with all processes, sintering is accompanied by an increase in the free energy of the system. The sources that give rise to the amount of free energy are commonly referred to as the driving forces for sintering. The main possible driving forces are The curvature of the particle surfaces An externally applied pressure A chemical reaction

Modern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an ironrich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.
Steel Making Process Steps: The first step involves mining iron ore or as easy it can be described as the first step in the process of making steel from iron ore. This is a very polluting process that uses coal for blasting, etc. It releases several pollutants such as oxides of sulphur, PM, and fugitive dust.
The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from Mta capacity to 28 Mta in the forthcoming years.
