| Abstract: |
| The dissipative structure theory was briefly introduced, four conditions to form dissipative structure were concluded, and the process of microwave reducing roasting of low-grade zinc oxide ore was analyzed with the theory of dissipative structure. The optimum technology parameters include the amount of active carbon powder of 4.26%, microwave power of 630 W, the heating time of 10 min. As a result, the leaching rate of zinc and iron is 85.36% and 33.25%, respectively. |
