Extracting iron from iron ore using a blast furnace.The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke.Coke is produced by heating coal in the absence of air.Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
Processing iron ore concentrate - mc world.Iron ore concentrate - iron ore.Iron ore concentrate iron ore concentrate is an output product from processing ores which have been grinded to separate disadvantageous elements and produce a higher quality product with about 65 iron in comparison with the fine and lump.
Iron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores.This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
The processing of the iron ore commences once the ore has been transported to the sorting plant from the underground and surface mines.The processing takes place in three stages sorting, concentration and pelletizing.Once the iron ore concentrate has passed the pelletizing plant, the end product small, round iron ore balls, known as iron.
The extraction of iron from its ores is quite a technical process.The iron ore is first roasted in air to produce ironiii 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.
