The invention discloses a method for cooperatively extracting mercury and antimony from a mercury-antimony mixed ore, and relates to adsorption of mercury. The method for cooperatively extracting the mercury and the antimony from the mercury-antimony mixed ore comprises the following steps of 1, carrying out primary leaching and primary solid-liquid separation to obtain a mercury-antimony rich solution; 2, carrying out electrodeposition twice on the mercury-antimony rich solution to obtain a mercury-antimony alloy; 3, carrying out vacuum separation on the mercury-antimony alloy to obtain crude mercury and crude antimony; and 4, refining the crude mercury to obtain refined mercury and refining the crude antimony to obtain a 1# antimony ingot. The method has the characteristics that the operation is simple, the whole process is clean and environmentally friendly, and the recovery rate of the mercury and the antimony is high; and the comprehensive recovery rate of the mercury is greater than 99%, and the comprehensive recovery rate of the antimony is greater than 97%.
