    11.23.2 Process Description2-5,41 Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.The Six Main Steps of Iron Ore Processing Multotec Canada,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 crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.

  • Iron Ore,Production Process of Iron Ore,Iron Ore

    Iron ore is an important raw material for iron and steel production enterprises. After crushing, grinding, magnetic separation, gravity concentration etc, gradually we can get iron from natural minerals (iron ore). It is the mineral aggregates that contain iron or iron compounds which can be used economically. Production Process of Iron OreCreating Steel HowStuffWorks,Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.The heat of oxidation raises the temperature and keeps the iron molten. As the air passes through the molten pig iron, impurities unite with the oxygen to form oxides.
