Mineral processing is the art and technology of treating ores from the mining areas in order to separate the valuable minerals from the waste rock. It includes processes to provide a more concentrated material for the procedures of the following extractive metallurgy. The two main processes to increase the concentration of minerals are leaching and flotation.

 · In this study, a comparison of laboratory batch and column experiments on metal release profile from a mineral processing waste (MPW) is presented. Batch (equilibrium) and column (dynamic) leaching tests were conducted on ground MPW at different liquid–solid ratios (LS) to determine the mechanisms controlling metal release. Additionally, the effect of pH on metal release is also .

Monazite is a poorly soluble mineral of rare earth phosphate. It is an ore of the rare earths which is difficult to break down; in industry either concentrated sulphuric acid or caustic soda is used to attack finely ground monazite at between 140 °C and 400 °C. In these processes, the rare earths are converted into different solid compounds, undergoing an incomplete conversion.

 · Leaching is a process where metal ore is soluble and impurities are insoluble. Leaching is widely used in extractive metallurgy techniques which convert metals into soluble salts in aqueous media. The extraction of metals from their ores naturally is much cleaner and preferred than the traditional heap leaching using chemicals such as cyanide because the former ( bioleaching) leaves .

Leaching Process

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 chemical reaction of this leaching process is given as follows.
