| Abstract: |
| The oxygen enriched side blowing bath smelting of zinc leaching residue and low grade oxygen sulfur lead-zinc ore can realize the efficient utilization of low-grade oxygen sulfur lead-zinc ore. At present, there are problems of high energy consumption and low productivity due to high melting temperature and low fluidity of slag. Factage thermodynamic software was used to study the influence of slag composition on slag melting temperature through calculation. The results show that the melting temperature of slag rises gradually with the decrease of mass ratio of slag to ore. Under the same slag ore mass ratio, binary alkalinity has a great influence on the melting temperature of slag, which drops first and then rises with the decrease of alkalinity. When the mass ratio of slag to ore is 3.07 and w(CaO)/w(SiO2)=0.5, the melting temperature of slag reaches the lowest value of 1 327 ℃. |
