Although above system is recycled tailings, it can be difficult to the gold, silver, copper, lead, the zinc that contain in tailings
It extracts, and carries out separation and produce.
Summary of the invention
The object of the present invention is to provide a kind of non-ferrous metal slags to pass through pretreated comprehensive recycling process, can be by mineral
Valuable element in tailings all extracts.
Above-mentioned technical purpose of the invention technical scheme is that：
A kind of non-ferrous metal slag passes through pretreated comprehensive recycling process, which is characterized in that includes the following steps：
The first step, pelletizing：Slag and chlorinating agent are mixed, with pelletizer by the mixture system of slag and chlorinating agent
Ball；Second step, drying：Pelletizing obtained is subjected to preheating and drying；
Third step, high temperature chlorination roasting：Dried pelletizing is put into calciner and is roasted, the pelletizing after roasting is received
Collection gets up, and the dry dirt of roasting generation and wet dirt are also collected；
4th step, acidleach：Dry dirt and wet dirt are poured into the acid tower equipped with acidleach copper-containing solution and impregnated；
5th step, filters pressing：To the dry dirt and the progress filters pressing of wet dirt, obtained filtrate and filter residue after immersion；
6th step leaches：Filter residue is put into leaching equipment and is leached, leachate and residue is made, by leachate and filtrate
Mixing, remaining residue is lead；
7th step, turbulent flow electrodeposition：Electrodeposition is carried out to leachate and filtrate, bronze, silver powder, copper sheet and zine plate are ionized out.
By using above scheme, the pelletizing after roasting can be used as the use such as iron-smelting raw material, last lead, gold obtained
Powder, silver powder, copper sheet and zine plate purity are relatively high, can directly use.This technique can by lead remaining in mineral tailings,
Gold, silver, copper and zinc extract, and completely handle mineral tailings realization, complete the complete process to solid waste or dangerous waste, discard
Object discharge is relatively low, reduces pollution of the mineral products to environment, the withdrawal ratio of various valuable metals is relatively high, and economic well-being of workers and staff is good.
Preferably, the waste water generated after turbulent flow electrodeposition is imported in leaching equipment, reused.
It by using above scheme, is able to carry out waste water and recycles, make full use of metal ion remaining in waste water
And leaching solvent, both reduce the discharge of waste, and also reduces processing cost.
It is roasted preferably, calciner is located in closed space.
It floats in air by using above scheme since the dry dirt generated in roasting process can raise, closed space
The floating away rear amount lost of dry dirt can be reduced to the greatest extent, both reduced the pollution to environment, and also improved the quantum of output of unit raw material.
Preferably, dry dirt is extracted at wet dirt by exhaust equipment, mix dry dirt with wet dirt.
By using above scheme, dry dirt is directly mixed with wet dirt, facilitates staff is same to transport to next
Walk process.
Preferably, raw material iron content is detected before roasting, the iron content for then detecting the pelletizing after roasting before
Detection is divided into high-iron-content pellet and low iron ball group.
By using above scheme, high-iron-content pellet can directly send to experienced steel mill and be smelted iron, and low iron ball group can send to
Construction site is used as building material, is carried out the sale transport that classification is conducive to the later period to pelletizing, is enable different pelletizings
Suitable place is sent to use.
It is dried preferably, the pelletizing made is put into dryer.
By using above scheme, dryer can dry pelletizing with carrying out constant temperature high efficiency, sufficiently carry out to pelletizing pre-
Heat, drying effect are got well than traditionally using air-heater drying effect.
Preferably, when leachate is mixed with filtrate, while extractant is added and is extracted.
By using above scheme, valuable metal in leachate can be extracted to organic phase by extraction, quasi- for subsequent electrodeposition
For electrolyte, overall recovery efficiency is high.
Preferably, after addition extractant is extracted in leachate and filtrate, then anti-stripping agent is added into mixed liquor,
It stirs evenly.
By using above scheme, the valuable metal in leachate and filtrate can be enriched with by anti-stripping agent, can first be returned
Receiving portions valuable metal improves recovery efficiency, and since electrolytic deposition process makes regeneration of sulfuric acid, can return to and is used as to be stripped or leach,
Sour consumption is reduced, total operation expense is reduced.
Preferably, after slag to be mixed with chlorinating agent to completion, by mixed slag and chlorinating agent pour into damp mill into
Row profit mill.
By using above scheme, profit mill can be improved green ball strength, reduces powder rate of dry balls, makes under the fineness of Iron concentrate
Drop, bentonite ore ratio reduces, pelletizing grade rises.
Preferably, filter residue enters in next step after the multiple filters pressing of filter press.
By using above scheme, filter press can be greatly reduced in final filter residue obtained by multiple filters pressing containing filter
The amount of liquid makes filter residue can be improved leaching efficiency when leaching, and reduces the residual of valuable metal in filter residue.
In conclusion the invention has the advantages that：
1. the pelletizing after roasting can be used as the use such as iron-smelting raw material, finally lead obtained, bronze, silver powder, copper sheet and zine plate are pure
It spends relatively high, can directly use.This technique can extract lead remaining in mineral tailings, gold, silver, copper and zinc,
Mineral tailings realization is completely handled, the complete process to solid waste or dangerous waste is completed, waste discharge is relatively low, reduces mineral products
The withdrawal ratio of pollution to environment, various valuable metals is relatively high, and economic well-being of workers and staff is good；
2. being able to carry out waste water to recycle, metal ion and leaching solvent remaining in waste water are made full use of, was both reduced
The discharge of waste, also reduces processing cost；
3. valuable metal in leachate can be extracted to organic phase by extraction, electrolyte is prepared for subsequent electrodeposition, total recycling effect
Rate is high；Valuable metal in leachate and filtrate can be enriched with by anti-stripping agent, can first recovery section valuable metal, improve back
It produces effects rate, and since electrolytic deposition process makes regeneration of sulfuric acid, can return to and be used as to be stripped or leach, reduce sour consumption, make total operating cost
With reduction.
