Lustre is a good diagnostic property since most minerals will always appear either metallic or non-metallic. There are a few exceptions to this (e.g., hematite in Figure (PageIndex{1})). Hardness. One of the most important diagnostic properties of a mineral is its hardness. In 1812 German mineralogist Friedrich Mohs came up with a list of 10 ...

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.

Bauxite Mineral. Bauxite is a mixture of minerals which contain, as well as impurities, different concentrations of hydrated aluminium oxides. Gibbsite (alumina trihydrate), boehmite, and diaspore (alumina monohydrates) are the main ore minerals. Bauxite is a high-aluminium-content rock. That is the main ore that aluminium is mined from.

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 …
