Abstract:

 

The hydrometallurgical treatment of zinc sulfide concentrates involves  the separation of zinc from iron, since most zinc concentrates contain  5-12% iron.  Several processes, such as hematite, magnetite, goethite  and jarosite, have been developed for the removal of iron from  solution prior to zinc electrolysis.  The precipitation of iron is  controlled by a set of thermodynamic and kinetic factors operative  both in iron solutions and in precipitates.  Identifying these factors  and their relations is important for the control of these processes.   Inbrief, thermodynamic stability regions of iron compounds formed  during the jarosite and goethite processes, which are commercially  used in the zinc industry, are outlined in this paper.
