Description
Technical field
The present invention relates to wet processes to practice zinc technical field, and in particular to de-magging Novel environment-friendlymaterial material in a kind of Zinc Hydrometallurgy Process
Production method.
Background technique
In the production of zinc refining, 80% or more is accounted for using Zinc hydrometallurgy process.The raw material zinc sulphide of wet zinc-making system
Magnesium in concentrate and partial supplementary material constantly enters system, and recycles and be enriched in wet zinc-making system, if do not taken effectively
Measure, content of magnesium can be continuously increased in system, can reach 40g/L or more so that magnesium be easy in the lower pipeline of temperature or
Chamber wall crystallization improves blocking risk, causes potential threat to zinc abstraction equipment；High magnesium ion concentration will increase solution viscosity,
Current efficiency is reduced in electrolytic process, increases energy consumption；Meanwhile high magnesium ion concentration can reduce the zinc output efficiency of system.Cause
This needs the magnesium that will be enriched in solution to clear out of system, to guarantee the balance of magnesium in zinc abstraction system, it is ensured that zinc electrolysis is smooth
It carries out.
Currently, most common except magnesium method has in wet zinc-making system: crystallisation by cooling method, the heavy zinc row magnesium processes of neutralization etc.,
There is its advantage and disadvantage.The principle of crystallisation by cooling method demagging is the variation based on magnesium salts solubility, when the close saturation of content of magnesium, is adopted
With pressure or Temperature fall, Mg2+Then with MgSO4 Crystallization is precipitated, but in actual operation, often there is a large amount of zinc sulfate,
The salts such as calcium sulfate are precipitated simultaneously, keep demagging effect undesirable, while also resulting in a large amount of losses of zinc.And it neutralizes heavy zinc and arranges magnesium processes
It is that addition lime carries out neutralization precipitation in liquid after electrolysis, is precipitated out zinc, magnesium plasma all from solution, the method is not only
Large quantities of lime is consumed, many waste residues and waste water are generated, while causing the loss and cost recovery raising of a large amount of zinc.
The method of above-mentioned removing magnesium ion, first to recycle zinc as major measure, and zinc can only be with the shape of material containing zinc
Formula recycling, cost recovery is all higher, and the rate of recovery of zinc is also undesirable.Several distinct issues are faced with, first is that the quantity of slag is big, very
The problems such as difficult discharge for fundamentally solving slag, storage and comprehensive utilization；Second is operating cost height；Third is the waste residue generated
The value of comprehensive utilization is low, and long-term environmental protection management difficulty is big, and enterprise's long period steady production can not be supported to run.
Thus, it explores new technique and realizes that the open circuit of magnesium in zinc hydrometallurgy is very important.
Summary of the invention
The purpose of the present invention is to provide a kind of production methods of de-magging Novel environment-friendlymaterial material in Zinc Hydrometallurgy Process, can
Selectivity gets off the magnesium precipitate in zinc electrolyte, and reduces environmental pollution.
In order to solve the above technical problems, the invention adopts the following technical scheme:
The production method of de-magging Novel environment-friendlymaterial material in a kind of Zinc Hydrometallurgy Process, comprising the following steps: delay basic zinc carbonate
Slow be added in hydrofluoric acid is synthesized, while the performance improving agent A and activator B prepared in advance is added, and synthesizes de-magging Novel ring
By being dehydrated, being dried de-magging Novel environment-friendlymaterial material can be obtained, filtrate returns to preparation hydrofluoric acid and follows in the slurry for protecting material
Ring uses.
Further, the mass percentage concentration of basic zinc carbonate is 57%.
Further, the temperature of Synthesis is 30-80 DEG C.
Further, the mass percentage concentration of hydrofluoric acid is 12-30%.
Further, performance improving agent A 7L and activator B 3L is added in every cube of basic zinc carbonate.
Further, generated time 2-8h.
Compared with prior art, the beneficial effects of the present invention are:
1. de-magging Novel environment-friendlymaterial material of the invention can selectively get off the magnesium precipitate in zinc electrolyte, while to electric zinc system
System will not be brought a negative impact, and just meet the needs of zinc industry development.
2. the zinc-containing solution Returning process after demagging uses, fundamentally solve that domestic demagging at present is expensive and ring
The heavy-polluted problem in border.
