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.

Roasting and Processing Sulpho-telluride ore to recover gold. This roasting plant, since closed down, was equipped with eight standard 70-spindle Edwards roasters, though only four were finally in use. Fuel was supplied to four ports on each furnace in the form of pulverized lignite of 8500 B.t.u. value prepared at a central plant.
