Bauxite mining, which is considered as surface mining, is land extensive, noisy and dusty. Mining pits are often interspersed with small rural communities, thereby requiring companies relocate the people and/or to monetarily compensate them. An increasing concern is the loss of habitat for Jamaica's unique plant and animal species.

Bauxite has a low Mohs hardness of 1.5-3.0, a dull, earthy luster, and low specific gravity of 2.0-2.5. Bauxite forms in moist tropical or subtropical climates when the aluminum-silicate minerals in clayey soils are leached and converted to basic oxides.
Bauxite is a natural product of weathering and occurs as a white to grey to reddish orange-brown crust at or near the Earth's surface in regions that have, or have had in the past, high rainfall. Bauxite is generally hard, …
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amo…
Ongoing research to evaluate the properties of bauxite is being carried out by Australia and Brazil, while an ongoing research project in China suggests that bauxite has various behaviours, based on the parent rock and how the materials weather.
Physical Properties Bauxite Bauxite is normally a soft substance, having a Mohs hardness of only 1 to 3. It has a pisolitic structure, an earthy sheen, and a specific gravity of 2.0 to 2.5, ranging from white to grey to reddish brown. These characteristics are important for recognising bauxite, but they have no bearing on its value or utility.
In this study, physical, chemical, and surface charge properties of bauxite residue derived from a combined process were investigated. Results indicated that the main alkaline solids in bauxite residue were katoite, sodalite, and calcite. These minerals also lead to a higher acid neutralizing capacity of bauxite residue.
Bauxite is a sedimentary rock, which contains relatively high levels of aluminium. It is the main source of aluminium and gallium. Bauxite appears dull in luster and is reddish-brown, white, or tan in color. The rock was discovered in 1821 by French geologist Pierre Berthier, near the village of Les Braux in Provence, southern France.
Bauxite physical properties Bauxite is typically a soft material with a Mohs hardness of 1 to 3. It has a pisolitic structure, an earthy sheen, and a specific gravity of 2.0 to 2.5 and ranges in colour from white to grey to reddish-brown. These properties aid in identifying bauxite, but they do not influence its value or application.
Bauxite is a natural, very hard mineral used predominantly in road systems for its high-friction and anti-skid properties. The majority of public sector systems will specify that Calcined Bauxite be used in their road and pedestrian crossing installations.
Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals, plus various mixtures of silica, iron oxide, titania, aluminosilicate, and other impurities in minor or trace amounts.

Answer: Bauxite typically has a Mohs hardness range of 1-3, making it a soft substance. It has an earthy shine, a specific gravity between 2.0 - 2.5, and exists in white, grey and reddish brown colours. These traits are essential for distinguishing bauxite, but they show little influence on how valuable or helpful it is.
