Characteristics of the iron ore processing technology in recent years. 1. Pre separation process (1) Pre separation of low grade magnetite ore. The successful development and application of big lump ore dry permanent magnetic separators and high efficiency magnetic drums (magnetic pulleys) have enabled the beneficiation of low grade magnetite ore to discard 10 to 30 of tailings in advance.
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.
