    Oct 23, 2018· S + O 2 → SO 2. 4 P + 5 O 2 → 2 P 2 O 5. Roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity, It is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus.. Roasting of iron is very important in the ore dressing process but this process pollutes the environment, Ore

    IntroductionIron Ore ExtractionIron Ore ProcessingSintering and PelletizingAfter the iron ore has been prepared by crushing and grinding during ore extraction, the ore is actually processed. The aim of this is to reduce the undesirable high proportion of admixtures to a desired minimum in order to increase the iron content. This is done by processes such as flotation or magnetic separation. Subsequently, the milled ores are lumped by sintering or pelletizing in order to optimize chemical reactions in the blast furnace process. Ore processing (or ore dressing) is the separation of ir
