Gold ores are natural mineral formations containing gold in varying quantities. Gold is typically found in combination with other minerals and elements, and the composition of gold ores can vary widely. Common minerals associated with gold ores include quartz, pyrite, arsenopyrite, chalcopyrite, and tellurides like calaverite and sylvanite.

In the context of its processing, gold deposits are typically classified, for the purposes of simplification, as: 1) free milling, and 2) refractory ores (including complex and carbonaceous). Based on their mineralogical characteristics and their mineral processing techniques required to liberate them, however, gold ores can be classified further.
