Processes and Procedures in the Extraction of Iron

The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) 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 into it from beneath via small pipes known as tuyeres.

The Chemical Reaction That Causes Rust

Jan 22, 2020· The Chemical Reaction That Forms Rust . Although rust is considered the result of an oxidation reaction, it's worth noting not all iron oxides are rust. Rust forms when oxygen reacts with iron, but simply putting iron and oxygen together isn't sufficient. Although about 21% of air consists of oxygen,   rusting doesn't occur in dry air. It

How to Write the Balanced Chemical Reaction for the

Apr 26, 2018· If you're interested in writing a balanced equation for the entire process, you need only know the initial reactants and the products of the reaction. The reactants are iron (Fe), oxygen (O 2) and water (H 2 O), and the product is iron (III) hydroxide Fe(OH) 3, so Fe + O 2 + H 2 O → Fe(OH) 3. In a balanced equation, the same number of oxygen
