- Bauxite is the most
important aluminium ore.
- Bauxite is
reddish-brown, white, tan, and tan-yellow.
- They were formed by
lateritization (see laterite) of various silicate rocks such as granite,
gneiss, basalt, syenite and shale.
- Bauxite is the name
for a mixture of similar minerals that contain hydrated aluminum
oxides.
- Bauxite is a
naturally occurring, heterogeneous ore composed chiefly of aluminous
oxide minerals as gibbsite (Al2O3.3H2O), the trihydrate, bohemite,
diaspore (Al2O3.H2O) and monohydrates etc.
- The major
technological barriers to improving the Bayer process are the inability
to significantly increase the rate of alumina precipitation, the
inability to increase thermal efficiency, the need for higher
temperature and pressure digestion, and a relatively low
yield.
- ResonantSonics
technology has the potential to yield improvements in several of the
Bayer processing steps.
- M2M-Technology is a
novel, patented combination of well known process and equipment
technology. Implementation of an M2M facility typically reduces specific
residue generation by 8% and increases alumina production by
4%.
- Bauxite is typically
mined in open-pits and either processed into alumina near the mining
operation, or shipped to smelting markets
around the world for
processing.
- Eighty percent of
world bauxite production, mainly from large blanket type deposits is
from surface mines, with the rest, mainly from Southern Europe and
Hungary, from underground excavations.
- The typical
processing of Guyanese bauxite is straightforward: Bauxite is crushed to
-9 cm, washed and screened, crushed to -4 cm,
rewashed, then rotary
kiln calcined, with some final de-ironing before shipment.
- There is a large
U.S. market for bauxite processing.
- Bauxite production
has increased annually since 1998 at an average rate of almost
6%py.
- Demand for
non-metallurgical grades of bauxite and alumina is growing less quickly
than smelter grade material for aluminium production.
- Europe, the second
largest market, is projected to register sales of 52 million metric tons
by 2010.
- It is used in the
production of synthetic corundum and aluminous Refractories.
- Bauxite is widely
used in the manufacture of refractory bricks, which are utilized as
lining materials in furnaces and kilns.
- Bauxite is used in
the manufacture of alum, aluminous sulphates and other
chemicals.
- Refractory-grade
bauxite also is used to produce brown-fused alumina, a significant
product in China.
- Strong growth in the
demand for aluminium, especially from China, is expected to keep unit
values for bauxite relatively buoyant.
- On a world-wide
average 4 to 5 tonnes of bauxite are needed to produce two tonnes of
alumina, from which one tonne of aluminium can be produced.
