Introduction is given to experiment on changing reaction zone lining into Mg Cr Al bricks in volatilization kiln for treating zinc leaching residue and practice for achieving domestic leads in same industry after continuous operation for 244 days by using this kind of brick lined volatilization kiln.

,twostage rosting-weak acid leaching and pressure leaching,that have achieved good results with zinc leaching rates of above 96% and iron leaching rates of around 50% and shown good prospect for future industrialization.

Study on sticking mechanism of kiln crusts in zinc leached residue volatile kiln;

An experimental study of the enrichment of indium and germanium via high temperature volatilization of zinc residue;

This paper proposes an expert control and fault diagnosis scheme for the leaching zinc process, which concerns determining and tracking the optimal pHs of the leach overflows, and ensuring the safe running of the process.
