Zinc atom, uses machinery ore grinding to be difficult to the method for ore dressing make zinc, ferrum, indium separate, causes the zinc concentrate of ore dressing output to contain relatively
High ferrum is high, and is associated with the metals such as the indium of high level, copper.Association ferrum in zinc concentrate is at zinc sulfide concentrates roasting process
In inevitably produce a large amount of zinc ferrites and the ferrite of other a small amount of valuable metals, zinc ferrite is at neutral leaching process not
Destroyed, stay in zinc leaching residue with zinc oxide and most ferrum, indium and the most copper not being dissolved.
In order to destroy zinc ferrite to reclaim zinc and indium, rotary kiln evaporation method or hot acid generally need to be used to leach-sink ferrum skill
Art processes.Wherein rotary kiln evaporation method can effectively destroy zinc ferrite, and output zinc oxide and Indium sesquioxide. return zinc metallurgy flow process and return

The valuable metals such as heavy ferrum process zinc, indium, copper are avoided to enter scum, it usually needs first the Fe3+ in leachate to be reduced to Fe2
+, then reclaim copper, indium with displacement method with neutralizing hydrolysis method.The most conventional method is in acid condition, utilizes zinc sulfide concentrates
Ferric ion in reducing leaching liquid, but owing to concentrate utilization rate is low, excess zinc concentrate need to be added, it is easily caused hot acid leachate
In copper generate cuprous sulfide precipitation and enter in reducing slag, and unreacted residue zinc concentrate needs special disposal, causes the method
There is the problems such as valuable metal leaching rate is low, technological process is complicated, energy consumption is high such as zinc in material, indium, copper.
Therefore, how to realize the efficiently leaching of zinc leaching residue, solve the problem that zinc-iron separates and valuable metal efficiently utilizes
Become a key technology difficult problem for zinc hydrometallurgy.
