The invention provides a process for surely obtaining rhodium sponge with content of tellurium reduced, while recovering Rh in rhodium sponge from a water solution of chlordene ammonium rhodate containing Te. By analyzing mass concentration ratio Te/Rh of contained Te in the solution, when it is determined that Te/Rh is higher than a predetermined value, a special step for separating Te from the solution is repeated, until the value of Te/Rh is below the predetermined value to obtain a chlordane ammonium rhodate solution with Te/Rh reduced, and rhodium sponge is obtained by reduction process of the solution.
