Iron ore is a crucial raw material for the global steel industry, and its supply chain is a complex network that involves multiple stakeholders and activities. The iron ore supply chain begins with the mining of iron ore, which is …
Six steps to process iron ore. 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
The production of steel from iron ore (primary steel) requires a number of energy-intensive steps with a cumulative energy input of 15–24 GJ/t, much of it as coal, while the melting of pure scrap steel to produce new steel (recycled or secondary steel) requires only 1.3–6.0 GJ/t [2], all of which can be supplied by electricity that ...
Now that the iron ore is in pellet form ready for processing, the steel-making process begins. The first step is iron smelting, which is an industrial process used to extract usable iron from raw ore with heat and chemical agents. Iron smelting takes place in a blast furnace for intense heating, along with limestone and coke, and converted to ...
Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet Company, an iron ore mining and processing facility located on the Mesabi Iron Range of Minnesota. Creating steel from low-grade iron ore requires a long process of mining, crushing,
#1. Making the Iron. Steel is a metal alloy made of iron and carbon. Thus, the steel manufacturing process starts by making iron. To do this, limestone, coke, and iron ore are combined and put into a blast furnace. The elements are melted together to create a hot metal known as molten iron. #2. Primary Steelmaking.

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
