Process for smelting zinc with wet method of high temperature and high acid-jarosite iron removing-iron vitriol slag pickling by two stages

The invention provides a process for smelting zinc with a wet method of high temperature and high acid-jarosite iron removing-iron vitriol slag pickling at two stages, belonging to the technical field of non-ferrous metal smelting. The process comprises the following steps of neutral leaching, acid leaching at the first stage, acid leaching at the second stage, pre-neutralizing, settling vitriol and pickling to obtain zinc metal with a high recovery rate. The total recovery rate of zinc metal is 94.45%. The loss of valuable metal in iron vitriol slag is less, the recovery rate of metal is high, and the pollution of vitriol slag to the environment is improved.
