THE EFFECTS OF IMPURITIES ON LIME QUALITY Penta
Magnesium Oxide (MgO) is a problem in high calcium lime as it affects the reactivity of the lime The dissociation temperatures (temperature when CO2 is driven off) for high calcium oxide is about 898°C, while magnesium oxide is about 760°C This makes the magnesium oxide “hard burned” and therefore, slow slaking and less activeThe scheme imposes limits on these chemical components, as shown in Table 1 For example, high purity limestone has more than 543%CaO (equivalent to 97% calcium carbonate), less than 10% MgO, less than 06% SiO2 and less than 01% Fe2O3 Locations where high purity limestone was found to occur are indicated on the map with a red starLimestone resources NERC Open Research Archive
