Claims (4)

1. Способ выщелачивания цинкового концентрата в атмосферных условиях в присутствии трехвалентного железа, отличающийся тем, что цинковый концентрат обрабатывают в условиях, где, помимо трехвалентного железа, имеются такие зародыши ярозита, содержание серной кислоты на стадии выщелачивания поддерживают в интервале 10-40 г/л, а температуру поддерживают в области 80°С - точки кипения раствора и на стадию выщелачивания подают кислород, так что цинковый концентрат растворяется, а железо осаждается в виде ярозита.1. The method of leaching zinc concentrate in atmospheric conditions in the presence of ferric iron, characterized in that the zinc concentrate is processed in conditions where, in addition to ferric iron, there are such nuclei of jarosite, the sulfuric acid content in the leaching stage is maintained in the range of 10-40 g / l and the temperature is maintained at 80 ° C — the boiling points of the solution and oxygen is supplied to the leaching stage, so that the zinc concentrate dissolves and the iron precipitates in the form of jarosite. 2. Способ по п. 1, отличающийся тем, что цинковый концентрат подают в конечную часть такой стадии, где одновременно выщелачивают ферриты цинкового огарка и осаждают растворенное железо в виде ярозита. 2. The method according to p. 1, characterized in that the zinc concentrate is fed to the final part of such a stage, where zinc cinder ferrites are leached out simultaneously and dissolved iron is precipitated in the form of jarosite. 3. Способ по п. 1, отличающийся тем, что цинковый концентрат подают в способ, где из остатка нейтрального выщелачивания цинкового огарка сначала выщелачивают ферриты, а затем на отдельной стадии способа осаждают железо в виде ярозита, так что цинковый концентрат подают в конце стадии осаждения ярозита. 3. The method according to p. 1, characterized in that the zinc concentrate is fed to the method, where ferrites are first leached from the neutral zinc leach residue and then iron is precipitated in the form of jarosite in a separate process step, so that the zinc concentrate is fed at the end of the precipitation stage jarosite. 4. Способ по п.1, отличающийся тем, что ярозит рециркулируют от конца стадии выщелачивания/осаждения в начало. 4. The method according to claim 1, characterized in that the jarosite is recycled from the end of the leaching / precipitation stage to the beginning.
