The process of dissolving soluble minerals from a solid ore or concentrate by means of an alkaline solvent. E.g. Sodium hydroxide is used for dissolving aluminium from bauxite and leaching wolframite and scheelite ores. Ammonium hydroxide is used for extracting metals such as copper and nickel that form soluble ammines from their ores.
