AbstractA practical and economical new technology is developed to treat the chromium containing residue which consists of carbonate leaching of the residue - extraction of valuable magnesium - chromium detoxification - preparation of magnetic ferrite. In this paper effects of reaction temperature, CO2 partial pressure, liquid to the residue ratio, addition of ammonium carbonate acid applying ultrasonic field on the yield of magnesium in carbonate leaching experiments are investigated under the atmospheric condition. The results calculated by the unreacted shrinking core model (USCM) show good agreement with the experimental data. The new technology will bring about high environmental and economic benefits.
