An apparatus and method utilizing a strip solution for removing gold from the loaded activated carbon used to accumulate such gold leached from gold bearing ore, and for electrically removing such gold from the strip solution by electrowinning. The apparatus includes a pair of strip columns fillable with loaded activated carbon. The strip columns are connectable individually and in series in respective continuous loops using a valved crossover pipe assembly to an electrowinning device, with the strip solution being pumped therethrough. The loaded carbon in the first strip column is firstly partially stripped with the valved crossover pipes closed to flow, such stripping being completed therein by opening flow therebetween through the crossover pipes to serially connect the columns while the loaded carbon in the second strip column is being partially stripped, and closing the flow therebetween to complete the stripping in the second strip column, so as to more efficiently use the dynamics of the strip solution used therewith.
