The purpose of the present invention is to efficiently recover gold in metal sulfide ores at low cost. This gold recovery method uses an acidic leaching solution including a chloride ion and/or a bromide ion as an anion and copper and iron as a cation, and includes: a step for heating and leaching gold from a base metal sulfide ore into the acidic leaching solution; a step for causing the adsorption of gold in the acidic leaching solution onto activated carbon; and a step for obtaining a concentrated gold solution by eluting with an alkaline solution the gold adsorbed onto the activated carbon. |
