3. Application
Widely used in papermaking,
chemistry, rubber, Pharmaceutical, fertilizer, refractories and
building materials etc
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/20GP
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.
