Production of Iron And Steel
The most commonly used process for converting pig iron into steel is the basic oxygen process. In this process, pig iron and up to about 30% steel scrap is charged into a barrel-shaped refractory-lined converter into which an oxygen lance is inserted as shown in the below figure. Steelmaking in the basic-oxygen furnace.

The six main steps of iron ore processing
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.
Haber-Bosch Process
The Haber-Bosch process was one of the most successful and well-studied reactions, and is named after Fritz Haber (1868–1934) and Carl Bosch (1874–1940). Haber first proposed the use of a high-pressure reaction technique. Furthermore, in order to overcome the low conversion-per-pass of ammonia, he introduced an important concept: the ...
