mining steps for chemical separation of iron ore

  • Developments in chemical separation of iron ore

    Chemical separation of impurity elements such as silicon aluminum and sulfur from iron ores often occurs in the processing to remove phosphorus from the ore. The treatments may include caustic or acid leaching of the ore with or without a heating treatment and magnetic separations between treatment steps.

  • The Extraction of Iron Chemistry LibreTexts

    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.

  • Developments in the physical separation of iron ore

    The ore is mainly composed of magnetite hematite martite and quartz. It is very difficult to produce a highquality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% 75 μm.
