Description
Technical field
The present invention relates to a kind of high-sulfur copper cigarette ash wet processing and reclaim the technique of the valuable metals such as copper, particularly relate to a kind of in sulfuric acid medium Oxidation Leaching high-sulfur ash of copper converter reclaim the method for copper, i.e. sulfuric acid leaching copper cigarette ash under blowing air condition, leach liquor obtains electrolytic copper by extraction-electrolysis, from leached mud, reclaim lead, bismuth and silver, from raffinate, reclaim zinc and cadmium, belong to technical field of wet metallurgy.
Background technology
To the processing of copper cigarette ash, in early days take pyrogenic process as main, recent development trend is take wet method or wet method-pyrogenic process process integration as main.At present, copper cigarette ash mainly contains following several treatment process both at home and abroad:
Blast-furnace method
Blast-furnace method is that copper cigarette ash is added to tackiness agent, makes pelletizing.Pelletizing is packed together with flux, coke into melting in smelting furnace, lead smelting becomes lead bullion again, and copper is smelted into matte, and zinc forms tutty fume recovery, and arsenic is fixed with the form of arsenic matte.The problem that this method exists is that tackiness agent does not generally contain valuable metal, increases the treatment capacity of stove; In copper cigarette ash, the content of iron is low, and in order to obtain, fusing point is low, the slag of good fluidity, must add a large amount of ferrous materials, forms with working the slag; Simultaneously blast furnace smelting unavoidably produces secondary pollution, and the purity that reclaims product is not high, and the rate of recovery not high (40%-70%) of copper, lead, zinc.
Selecting smelting combination method
The basic procedure of selecting smelting combination method: copper cigarette ash is after leaching, solid-liquid separation, and the heavy copper of leach liquor displacement, is oxidized neutralized ex iron arsenic, and condensing crystal is prepared Zinc Sulphate Heptahydrate; Leached mud obtains copper ore concentrates, inferior concentrate, chats by ore dressing, and these three kinds of materials directly return to converter melting, and arsenic is enriched in mine tailing, stores up.This method lead and bismuth are dispersed, and the rate of recovery is low.
Wet method-pyrogenic process process integration
Wet method-pyrogenic process process integration basic procedure: dilute acid pretreatment ash of copper converter-displacement is sunk copper-deironing-condensing crystal and produced zinc sulfate.Leached mud is produced lead bullion further to reclaim plumbous grade for metal through fire reduction melting.This method weak point be fuel rate up to 30%, environmental pollution is more serious, valuable element comprehensive recovery is on the low side, product structure is unreasonable etc.
Full wet processing process
The identical point of full wet processing process and wet method-pyrogenic process integrated process is the recovery of copper and zinc all to adopt same process flow, and acid leaching residue is adopted to the technique of carbonate conversion-nitric acid leaching-sulfuric acid depositing.The method is fully used resource, has reduced environmental pollution, technology maturation.Shortcoming is that operating process is long, and deironing burden is heavy, is not suitable for processing the copper cigarette ash that sulfur-bearing is high.
Process copper smelting ash additive method and also have pressure leaching process, sodium sulphite-alkali system Oxidation Leaching method and villaumite lixiviation process etc.
Except above-mentioned technique, people have have also researched and developed the technique of various processing copper cigarette ash.For example
1. the Chinese invention patent that publication number is CN1493707 has provided " novel process that a kind of ash of copper converter slag is agglomerating and agglomerating formula thereof ", it is characterized in that: after first adding additive in ash of copper converter slag, roll over through mixing, be pressed into agglomerate, then drop into smelting in smelting furnace and reclaim plumbous; Its agglomerating formula is: in every 100 kilograms of slags, add 2-10 kilogram of lime, 2-10 kilogram cement, 5-15 kilogram bituminous coal.This technique has solved the poor problem of furnace charge air permeability in former smelting technology, can improve the throughput of smelting furnace, improves metal recovery rate, reduces energy consumption.
2. the Chinese invention patent that publication number is CN101519728 has provided " a kind of ash of copper converter is prepared the method for bismuth oxide ", first ash of copper converter is leached with dilute sulphuric acid, and sulphuric leachate reclaims copper, zinc; Then leached mud is added the sodium-chlor vitriol oil to leach, leach liquor is replaced with iron, obtains sponge bismuth; Again sponge bismuth is prepared to bismuth oxide through washing, nitric acid dissolve, transition, calcining again.This technological process is simpler, adopts wet process, good operational environment.
3. the Chinese invention patent that publication number is CN101519729 has provided " a kind of method of preparing lead sulfate tribasic with ash of copper converter ", its step comprises: leach ash of copper converter (1) with dilute sulphuric acid, obtains leach liquor and leaded, the bismuth leached mud of cupric, zinc; It is characterized in that its step also comprises: (2) add the sodium-chlor vitriol oil to leach leaded, bismuth leached mud, obtain bismuth-containing leach liquor and villaumite leached mud; (3) villaumite leached mud is transformed and obtains volatile salt conversion slag with volatile salt; (4) volatile salt is transformed to slag nitric acid dissolve; (5) volatile salt after nitric acid dissolve is transformed to slag lysate sulfuric acid precipitation; (6) the synthetic lead sulfate tribasic of lead sulfate precipitation sodium hydroxide precipitation being obtained.The method of this technique all adopts wet process, is leached the lead in cigarette ash is changed into lead carbonate by segmentation, then uses the acid-soluble solution of pin, sulfuric acid precipitation, then add sodium hydroxide to synthesize lead sulfate tribasic, this technological process is simpler, adopt wet process, good operational environment.
The method that above patent application 1 is mentioned, can not efficient recovery copper to reclaim metallic lead as main, the inevitable contaminate environment of fusion process.The equal conventional hydrometallurgical processes of method of patent application 2 and patent application 3 is processed copper cigarette ash, but is not suitable for processing the copper cigarette ash that sulfur-bearing is high.
Summary of the invention
