    Occurrence

    Gallium is found in various natural sources, including minerals, rocks, and the Earth's crust.

    • Relatively rare element, constituting about 0.0019% of Earth's crust
    • Never found as free metal in nature
    • No major gallium minerals; typically extracted from bauxite and zinc ores
    • Widely dispersed in small amounts in various minerals
    • Present in coal and other fossil fuels in trace amounts
