The coal gangue is mainly composed of quartz, silicate minerals, sandstones, carbonates, and aluminous rocks, whereas its primary chemical components include SiO 2, Al 4 (OH) 8 Si 4 O 10, and CaCO 3. Certain minerals such as chlorides, carbonates, and oxides are straightforwardly dissolved by the chemical solution and are lost during chemical corrosion.

The presence of basic gangue minerals such as calcite and magnesite will promote higher acid consumption and also influence pH changes affecting bacterial activity. Chemical and biological weathering in situ can provide access paths to solution transport, while slime and clayey formation can retard solution permeation and leaching kinetics.

Mineralogy in Copper Processing

In spite of the relatively low copper content in such gangue minerals, they can account for significant amounts of the total copper content of the sample which is rarely recovered during processing. A leachability ranking was developed to describe the amenability of individual copper minerals to acid leaching, where 1 represents complete leaching and 0 is totally unable to leach (Table 1).
