The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced ...
Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earths crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron making blast furnaces.
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.
When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crushers CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
