The invention discloses a dynamic desorption process for gold-loaded carbon, which comprises the following steps that: the gold-loaded carbon is in a loose suspension state when desorption solution flows by further to form a liquid-solid two-phase circulating fluidized bed; and in the dynamic desorption of the fluidized bed, when gold-loaded carbon particles at the axial central part of a desorption device overturn up and down, the gold-loaded carbon particles constantly move upwards under the action of the driving speed of the desorption solution, flow around and flow downwards along the circumferential wall of the desorption device when the gold-loaded carbon particles flow to the top, namely a highest interface of the fluidized bed due to the action of fluid resistance, are gathered into a central desorption solution inlet through the conical bottom when the gold-loaded carbon particles reach the bottom, flow upwards again to perform another cycle and repeat the process again and again to form the dynamic desorption of circulating fluidization. The process ensures that: the gold-loaded carbon particles perform various processes in a flow state; the whole desorption device is inan isothermal and uniform state compared with the conventional static desorption; and the mass transfer and heat transfer rates between the desorption solution and the carbon particles are large, which all strengthen the desorption chemical reaction process. The dynamic desorption of the gold-loaded carbon is more efficient than the static desorption, and desorption time is shortened.
