Description
Technical field
The present invention relates to a kind of methods of arsenic removal antimony fluorine in leachate from Zn dust, belong to zinc wet cleaning impurity removing technology neck
Domain.
Background technology
Zinc oxide fumes are essentially from Zinc Concentrate Roasting Dust, lead pyrometallurgical smelting flue dust, smelting iron and steel cigarette ash and zinc smelting
Slag and secondary resource pyrogenic attack flue dust are refined, in processing procedure, chlorine generation volatile compound ZnCl2、PbCl2, aoxidizing
It is collected in Zn dust, therefore zinc oxide fumes are very high containing chlorine, fluorine ion can enter electrodeposition system during dust treatment,
Corrode cathode-anode plate, be mainly shown as：Fluorine ion can destroy the pellumina on cathode aluminum plate surface, make fresh surface with zinc is precipitated
Allumen is formed, is bonded, zinc metal sheet difficulty is caused to be removed, cathode aluminum plate consumption is caused to increase.
Zn dust generally takes sulfuric acid leaching to handle in the industrial production, and zinc is recycled in the form of electric zinc, lead, silver, indium enrichment
Into in acid leaching residue, cadmium, copper segregation enter in copper-cadmium slag or copper ashes, then process for separation and purification are taken further to recycle again.But
Arsenic, antimony are harmful element into leachate, and As contents may be up to 5 ~ 30g/L, and Sb contents may be up to 0.5 ~ 5g/L, it is necessary to take
Measure removes arsenic antimony, As ＜ 1mg/L, Sb ＜ 1mg/L in supernatant in control, As ＜ 0.1mg/L, Sb ＜ 0.1mg/ in new liquid
Otherwise L is easy to cause in Purification of zinc sulfate solution and electrolytic process and generates poison gas AsH3And SbH3, and it is in ball that can cause zinc is precipitated
Luxuriant shape, striated and rarefaction reduce current efficiency.Since iron-holder is considerably less in flue dust, industrially frequently with
The mode of ferrous sulfate heptahydrate is added to supplement iron ion, realizes goethite crystals method or ferric hydroxide colloid removing arsenic, antimony member
Element.The shortcomings that the method is：Reaction time is long, needs 6 ~ 12h；The ferrous sulfate heptahydrate amount of supplement is very big, when in material contain As1
When ~ 2%, 10,000 tons of flue dust are often handled, require supplementation with 3000 ~ 5000 tons of ferrous sulfate heptahydrates, it is 120 ~ 2,000,000 yuan to be worth, cost
It is higher.
Therefore, flue dust is generally higher containing impurity such as arsenic, antimony, fluorine, and not iron content, using traditional Iron removal by two steps method, need to lead to
Compressed air adds a large amount of ferrous sulfate or ferrous ion or ferro-compound and oxidant hydrogen peroxide, reagent consumption
Greatly, production cost is high, and the reaction time is long, the sad filter of scum.Impurity fluorine is difficult to remove using traditional alkali washing process, after enrichment raising
Electrolysis system is endangered, reduces current efficiency.
Invention content
The purpose of the present invention is be directed to above-mentioned existing industrial technology there are the problem of, propose one kind from Zn dust leachate
The method of arsenic removal antimony fluorine, this method by adding in cleanser and oxide powder and zinc into flue dust leachate, one-step removal arsenic impurities,
Antimony, fluorine, dust removal rate is high, at low cost.
The purpose of the present invention is realized by the following means：
The method of arsenic removal antimony fluorine, includes the following steps in a kind of leachate from Zn dust：
（1）The Zn dust leachate of zinc abstraction production system is taken, adds in oxide powder and zinc and cleanser, temperature 30 under agitation
~ 90 DEG C, react 0.5 ~ 2h；
（2）Step（1）After reaction, stop stirring, then 0.1 ~ 1h of natural subsidence carries out plate-frame filtering, is purified slag
With liquid after removal of impurities, liquid contains arsenic≤2mg/L, containing antimony≤2mg/L, fluorine-containing≤240mg/L after removal of impurities.
Step（1）The flue dust leachate is the solution rich in zinc sulfate, and containing 100 ~ 160g/L of zinc, impurity content is high, contains
1 ~ 10g/L of arsenic, containing 0.2 ~ 2g/L of antimony, fluorine-containing 300 ~ 800mg/L；
Step（1）Purity >=98% of the oxide powder and zinc, addition are 1 ~ 10g/L.
Step（1）The cleanser is polysilicon acid polyferric sulfate, polymeric aluminium ferrum silicate or polymeric aluminum sulfate iron, and addition is
1~10g/L。
The features of the present invention：This method by into flue dust leachate add in cleanser and oxide powder and zinc, one-step removal it is miscellaneous
Matter arsenic, antimony, fluorine, dust removal rate is high, arsenic removal efficiency >=99%, except antimony rate >=98%, fluoride removing rate >=56%.Present invention process flow is short, examination
Agent is at low cost, and technological operation is simple.
