A color-coded periodic table of the elements displays each element's symbol and atomic number, with categories such as alkali metals, noble gases, halogens, transition metals, and actinoid elements distinguished by different background colors. — boron group element Modern version of the periodic table of the elements (printable).

Gallium does not occur in independent minerals in concentrated forms, meaning it is not mined as a primary ore. Instead, it is extracted as a by-product during the processing of other materials.12

The primary sources from which gallium is recovered include:

Zinc blende12
Iron pyrites12
Bauxite12
Germanite12

While a rare mineral known as gallite (CuGaS $_{2}$ ) does exist, it is not economically significant for the extraction of the metal.2
