Developments in chemical separation of iron ore

Jan 01, 2015  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.
