Aluminum Mineral Processing and Metallurgy: Iron-Rich

Mar 27, 2018The heterogeneous minerals in iron-rich bauxite are treated with conventional techniques, such as gravity concentration,magnetic separation,flotation,roasting followed by magnetic separation [21, 22] and chemical leaching [23, 24]. All of these conventional techniques cannot recover iron and aluminum from iron-rich bauxite effectively.

Bauxite: The aluminum mineral bauxite information and pictures

Bauxite is not a mineral, but rather a group of aluminum oxides. The term is generally used to describe the economically important mixture of these minerals, which form a mass of the individually classified members of Gibbsite, Boehmite, and Diaspore.

Bauxite an overview ScienceDirect Topics

The principal aluminum hydroxide minerals found in varying proportions within bauxite are gibbsite (trihydrated) and boehmite and diaspore (both monohydrated). The content of aluminum oxide is 30–60%. Bauxite is generally extracted by open cast mining from strata, typically 4–6 m thick under a shallow covering of topsoil and vegetation (Table I).
