    25.2 Extracting ores Mining of mineral resources Siyavula

    People extract valuable minerals from the lithosphere. Rock that contains high concentrations of valuable minerals are called ore. Various methods are used to locate potential sites for mining. Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining).

    TOPIC EIGHT EXTRACTION OF METALS CHEMISTRY FORM THREE

    To extract ores containing minerals, a chemical reaction must be used to separate the metal from other elements. The choice of the best method for extraction of a metal from its ore depends on the chemical reactivity of the metal to be extracted. Most ores contain metal oxides. To extract the metal, oxygen must be removed from it.
