The leaching with acids is one of many methods used for recovery of valuable components from industrial wastes. The processing and neutralization of this type of waste is very difficult due to toxic properties. This work shows the results of aluminum leaching from industrial black dross with oxalic acid depending on temperature, acid concentration, effect of liquid to solid ratio (L/S) and time process. The oxalic acid has not been used so far for processing of aluminum black dross. The main purpose of this work was to determine the optimal conditions of this process. The results show that the maximum leaching efficiency of aluminum (75.2 %) was obtained with a liquid to solid ratio of 20:1 using 0.5 mol·dm^-3 oxalic acid at 75 °C for 3 h.
