Overview. The hydrometallurgical processing of copper sulfide ore - as well as other minerals, such as iron ores, etc. - starts with crushing it into a fine powder and then separating the valuable minerals by means of a flotation process. Volumetric flow measurements are required to maintain a proper process control and efficiency.

Leaching Process Examples. The leaching process example includes the leaching of bauxite or Al2O3 . 2H₂O with the concentrated and heated sodium hydroxide. The concentrated NaOH here tends to dissolve the aluminium present in the given bauxite, while on the other hand, the impurities like SiO2, TiO2, and Fe2O3 do not get dissolved.

The Bayer process is the principal industrial method for refining bauxite to produce alumina (aluminum oxide). Lime, typically in the form of slaked lime (milk of lime), is used in several components of mineral processing. These include digestion, causticisation, filtration, filter-aid production (tri-calcium aluminate formation) and oxalate ...
