3. Application
1). In Magnesium Sulphate production, Magnesium Oxide MgO is a main raw material. Star Grace MgO great advantage is lower SiO2 content. That means the reactions are complete with less impurity. As a result, the yield of magnesium sulphate by 1MT MgO can be increased 200kg more than other source, and it is roughly 5MT/20’GP more.
2). In Abrasive production, Magnesium Oxide MgO can be used in abrasive stones. As the owner of magnesite, we have the best quality ore with low SiO2 and CaO content to calcine MgO powder, which is suitable to use in manufacture abrasive stones and grinding wheels. In the production, low CaO can make the stones hard. Low SiO2 can make the stones smooth. And moderate LOI can shorten the setting time.
3). In Agriculture, Magnesium Oxide MgO is used as magnesium supplement in compound fertilizer. Magnesium is an essential element for plant growth, as the central core of the chlorophyll molecule in plant tissue.
4). In Feed additives, Magnesium Oxide MgO is recognized as an essential nutrient for sheep or cows. Magnesium supplementation is needed to prevent hypomagnesaemia (grass tetany-staggers)
and milk fever (when calcium is also low) in beef (and dairy) cows from calving to peak milk production.
5). In construction, Magnesium Oxide MgO is used in produce industry floor, building boards and cement. Magnesium board is more and more popular in construction.
6). In Refractory, Magnesium Oxide MgO e is used as a refractory agent of crucibles.
7). In Water treatment, Magnesium Oxide MgO is used to remove the hydrogen sulfide of wastewater.
8). In Civil Engineering, Magnesium Oxide MgO has high capacity to absorb water to improve the soil coherence.
9). In Hydrometallurgy industry, Magnesium Oxide MgO is used to precipitate the hydroxides of metals from acid leachate solutions of their respective ores
10). In Soil Decontamination, Magnesium Oxide MgO is used to get rid of heavy metals of soil.
11). In power station and steel industry, Magnesium Oxide MgO is used as desulfurizer
12). In Rubber industry, MgO is used as filler, acid acceptor, anti-scorch ingredient, curing acid.
