PURPOSE: A precious metal recovery apparatus which operates according to the recovery amount is provided to measure the weight variation of a drum device and control the operation of a pump according to the weight variation, thereby improving the recovery efficiency. CONSTITUTION: A precious metal recovery apparatus comprises a liquid tank(10), a drum device(20), a circulating pipe(31), a pump(35), a control unit(40), and a weight measuring unit. The drum device collects precious metal included in fluid through electrolysis or anionic resin adsorption of the fluid in a drum. The circulating pipe connects the top and bottom of the liquid tank and the drum device to provide forward and reverse circulating paths. The weight measuring unit externally displays the weight variation of the drum device and transmits a corresponding signal. The control unit controls the operation of the pump according to the signal from the weight measuring unit.
