Abstract
The invention discloses a method for discharging germanium, arsenic and antimony impurities in zinc smelting. The method comprises that 1.1, ion content of a neutral leached ore solution is increased so that contact and adsorption probability is effectively improved, and pH at a neutral leaching finished point is increased so that regulation and control are realized and thus co-deposition is realized, 1.2, a precipitation base flow of 50m<3> is used, pH is controlled to 4.8-5 by CaCO3, and the germanium, arsenic and antimony impurities are discharged by press filtration and water washing. The method is used for zinc smelting.
Description
Technology neck city
The present invention relates to Metal smelting method, refer in particular in zinc abstraction the method for discharging impurity germanium, arsenic, antimony.
Background technology
At present, known in zinc abstraction, zinc electrolysis plate burns plate reason mainly impurity: cadmium, copper, cobalt, nickel element caused, and can, in zinc abstraction, to impurity: after cadmium, copper, cobalt, nickel are removed, still have zinc electrolysis plate to burn plate.
Summary of the invention
In order to overcome in existing zinc abstraction, zinc electrolysis plate burns plate reason mainly impurity: cadmium, copper, cobalt, nickel element caused.In zinc abstraction, to impurity: after cadmium, copper, cobalt, nickel are removed, zinc electrolysis plate can be still had to burn the deficiency of plate, the invention provides in a kind of zinc abstraction, the major impurity burning plate should be removed: cadmium, copper, cobalt, nickel, remove impurity again: germanium, arsenic, antimony.Work as germanium
arsenic
antimony
when PH > 2, electronegative characteristic; And ironic hydroxide Fe (OH)
3when PH < 5.2, positively charged characteristic: utilize the content improving ironic hydroxide in the solution, increase the probability of ironic hydroxide and germanium, arsenic, antimony Contact-sorption, the regulation and control of the pH value of solution between 2 < PH < 5, make germanium, arsenic, antimony electronegative, the positive lotus of hydroxide sheet iron strip, attract each other together, discharge after coprecipitation.Make zinc electrolysis plate not burn plate in zinc electrolysis is produced, save the expense and time that more renew electrolytic zinc-coated steel sheet, reduce cost, the normal continuous maintaining zinc abstraction is produced, and improves the Quality and yield that zinc is produced.
The present invention solves the new solution that its technical problem adopts: the method for discharging impurity germanium, arsenic, antimony in zinc abstraction, and comprising step is:
1.1, soak the iron-holder of rushing in the process of ore deposit in solution and soak terminal pH value in increasing in increasing;
1.1.1, with reducing iron removing reagent in liquation: the amount of bicarbonate of ammonia, sodium bicarbonate improves the Fe that heavy iron is arranged outward
3+, in solution containing Fe
3+amount, brings up to 4.5-5g/L from 2-2.2g/L, effectively increases Fe (OH)
3with
the probability of Contact-sorption;
1.1.2, with the Caco added in liquation
3amount regulates and controls the pH value of solution, the pH value of solution is adjusted to 2-2.2 < PH < 4.8-5, makes positively charged Fe (OH)
3electronegative with flocculation agent co-absorbed
cooperatively precipitate, significantly reduce the solid content in meutral innersion supernatant liquor, thus decrease because of flow out solution opacity and by impurity: germanium, arsenic, antimony bring to down one cleaning section;
1.2, with 50m
3heavy iron underflow, use Caco
3by the regulation and control of the pH value of solution between 4.8-5, after filter-press water-washing, by impurity: germanium, arsenic, antimony discharge with slag.
Like this, make the impurity in solution: single content of germanium, arsenic, antimony, reaches standard: 0.05mg/L respectively, the summation content standard < 0.2mg/L of germanium, arsenic, antimony.
The significant beneficial effect of the present invention is, in zinc abstraction, zinc electrolysis plate does not burn plate, makes zinc produce normal continuous, saving the expense and the time that more renew plate because burning plate, reducing production cost, improve the Quality and yield that zinc is produced.
Embodiment:
Below in conjunction with embodiment, the invention will be further described.
Discharge the method for impurity germanium, arsenic, antimony in zinc abstraction, comprising step is:
1.1, soak the iron-holder of rushing in the process of ore deposit in solution and soak terminal pH value in increasing in increasing;
1.1.1, use the iron removing reagent reduced in the solution: the amount of ammonium hydrogen carbonate, sodium bicarbonate, improve the Fe that heavy iron is arranged outward
3+, in solution containing Fe
3+amount, brings up to 4.8g/L from 2.1g/L, effectively increases Fe (OH)
3with
the probability of Contact-sorption.
1.1.2, with the Caco added in solution
3amount regulates and controls the pH value of solution, is adjusted to by the pH value of solution: 2.1 < PH < 4.9, makes positively charged Fe (OH)
3electronegative with flocculation agent co-absorbed
cooperatively precipitate, significantly reduce the solid content in meutral innersion supernatant liquor, thus decrease because of flow out solution opacity and by impurity: germanium, arsenic, antimony bring to down one cleaning section.
1.2, with 50m
3heavy iron underflow, use Caco
3by the regulation and control of the pH value of solution 4.9, after filter-press water-washing, by impurity: germanium, arsenic, antimony discharge with slag.
Like this, make the impurity in solution: single content of germanium, arsenic, antimony, reaches standard: 0.05mg/L respectively, the summation content standard of germanium, arsenic, antimony: < 0.2mg/L.
