- The process developed
in the U K to produce magnesium hydroxide from seawater is described,
together with the heat treatment that the hydroxide receives to produce
the active oxide.
- The operating
conditions that might be used for the production of good quality caustic
magnesia, i.e. caustic MgO with a low B2O3 content has been
determined.
- Worldwide, about 6
million tons of MgO are produced from sea water each year, with US
consumption around 730 thousand tons.
- MgO usage varies
widely. Higher-purity products produced from seawater/brine tend to be
used for refractory or industrial uses.
- The lime technology of
obtaining magnesium oxide from sea water and salt lake natural brine has
been finished rather well and become widespread not only in the USA, but
also in Great Britain, Germany, Austria, Mexico etc.
- MgO were produced
worldwide from magnesite ores with 1 million tons produced from brines
and seawater. China was the largest producer from natural magnesite,
accounting for nearly one half the amount produced.
- The process of
isothermally sintering magnesium oxide obtained from seawater by
substoichiometric and by overstoichiometric precipitation.
- Magnesium oxide
obtained from seawater2-9 is a high-quality refractory material, and its
advantages lie not only in the huge
reserves of seawater10 (1 m3
contains 0.945 kg of magnesium), but in the higher purity of the
sintered magnesium oxide (> 98 % MgO).
- The titration method is
used to monitor the carbonate content of sea water, fresh water and
lime, in order to ensure that calcium carbonate is not precipitated out
with magnesium hydroxide.
