The leaching slag cannot be reused in a steel mill due to its high residual content of zinc. The alkali fusionalkali leaching method can convert ZnFe 2 O 4 into ZnO, Na 2 ZnO 2 and Fe 2 O 3 through the alkali fusion process, and then zinc in the ZnO and Na 2 ZnO 2 can be leached out by the alkali leaching method, so as to achieve efficient ...
