Olivine Mineral | Physical
Olivine is typically inexperienced in color however also can be yellow-inexperienced, greenish yellow, or brown. It is obvious to translucent with a glassy luster and a hardness between 6.5 and 7.0. It is the simplest not unusual igneous mineral with these residences. The properties of olivine are summarized within the table.

Bauxite: The principal ore of aluminum.
Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale. It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite''s value or usefulness.

In addition, iron silicate is available in a wide range of particle sizes, which can be quite useful for removing very tough coatings such as chlorinated rubber that require the use of large particles.

Aluminium oxide
Both the hardness and abrasion-resistant characteristics of the coating originate from the high strength of aluminium oxide, yet the porous coating layer produced with conventional direct current anodizing procedures is within a 60-70 Rockwell hardness C range which is comparable only to hardened carbon steel alloys, but considerably inferior to the hardness of natural and synthetic corundum.

Earth Science for Kids: Minerals
Hardness - The hardness describes how easy it is to scratch the surface of a mineral. Scientists often use the Moh''s scale to describe hardness. Using the Moh''s scale, a "1" is the softest mineral and a "10" is the hardest. One example of hardness is diamond. Diamond has a hardness of 10 because it is the hardest of all the minerals.

Alumina hydrate is separated from bauxite ore using the Bayer process, with average particle size ranging from 80-100 micron. The block crystals of alumina hydrate impart good chemical reactivity. Alumina hydrate can react with a base as well as an acid, and finds use in many applications as raw material.

Mohs Hardness Scale
The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.
