The cleavage properties of a mineral are described in terms of the number of cleavages and, if more than one cleavage, the angles between the cleavages. The number of cleavages is the number or directions in which the mineral cleaves. A mineral may exhibit 100 cleavage surfaces parallel to each other. Those represent a single cleavage …
The photos above (Figure 3.16) show examples of different mineral habits. Habit, a property closely related to crystal shape, includes shape and size of crystal faces, how forms combine, how well developed different forms are, and the way multiple crystals grow together.Habit, thus, is the characteristic appearance a mineral can have.
A mineral is defined in part by a specific chemical composition.

1. Introduction. Bauxite residue (BR) is a highly alkaline, saline, and sodic waste material of the Bayer process, where aluminum (Al) is extracted from bauxite by caustic soda (Power et al., 2011; Santini et al., 2015).Currently, the global BR stockpile exceeds 4.6 billion tons, and the annual production is over 200 million tons per year.
Mineral Color. A mineral's color can be very distinctive at times. Take azurite (in the picture below), known for its deep blue color, or olivine, named for its olive green color.
Hematite is a mineral and a common form of iron oxide. It is known for its distinctive reddish-brown to black metallic luster. The name "hematite" is derived from the Greek word "haima," which means blood, due to its reddish color when it is powdered or in a fine-grained form.
