Description
Technical field
A kind of method the present invention relates to desulfurization enriching Cu silver antimony is evaporated in vacuo in many metal smelt slags from sulfur-bearing, belonging to has
Non-ferrous metal pyrometallurgy and vacuum metallurgy technology field.
Background technology
The many metal smelt slags of sulfur-bearing are lead bullion liquation decoppering and the sulfur-bearing metallurgical slag for adding sulphur copper removal process to produce.Removed in liquate
During copper, the reduction of solubility with temperature of the Cu in lead liquid and reduce, when lead liquid temperature degree drops to below 1225K, analysis
The crystallization for going out is not fine copper, but the copper-lead solid solution containing Pb, it is floated on lead liquid level with solid state.While the As in lead bullion
Copper arsenic and copper-lead compound are formed with Sb and Cu, and the impurity element such as almost all of Fe, Ni, Co, S, because insoluble in lead
Also float on lead liquid level.After lead bullion is through liquation decoppering, the copper in lead is remained in typically using adding the method for sulphur copper removal to remove, formed
Cu2S density ratio lead is small, but insoluble in lead in, float on lead liquid level in solid dross state.Contain in many metal smelt slags of sulfur-bearing
Lead amount is very high but cannot directly enter lead refinery practice, because the impurity such as Cu, Ag, Sb, S, As, Fe, Ni, Co therein is to lead
Property has a great impact, for example, its hardness is increased toughness reduction, corrosion resistance decrease etc..Therefore the reply many metal smeltings of sulfur-bearing
Refining slag otherwise processed, and the various valuable metals of synthetical recovery.
At present, many metal smelt slags of sulfur-bearing are typically processed using soda iron chip filter, to reclaim copper therein, lead and expensive
Metal.Conventional pyrogenic process recovery process also has reverberatory smelting method, blast-furnace method, converter smelting process, electric furnace smelting process.It is wet
Method technique has the acid-hatching of young eggs, ammonia leaching process and alkaline leaching.The lead bullion that pyrogenic process recovery process is obtained returns refining, and copper matte regulus reclaims copper, and pyrogenic process is returned
Receipts process energy consumption is high, and long flow path, noble metal dispersion, production cost is high.Wet recycling process produces a large amount of waste water, waste liquid, increases
The cost of sewage disposal.Additionally, many metal smelt slags of sulfur-bearing meeting substantial amounts of lead skim of output when leaching, brings to solid-liquor separation
It is greatly difficult.
Method for being evaporated in vacuo processes many metal smelt slags of sulfur-bearing, Chinese invention patent application publication No.
CN102676832A discloses a kind of method that copper dross slag vacuum distillation separates copper and lead, and it steams there is provided a kind of copper dross slag vacuum
Be placed in copper dross slag in vacuum environment from copper and the method for lead by cut, adds reducing agent coke powder, is 5-200Pa, temperature in pressure
To be carried out under conditions of 900-1300 DEG C separated 30-180 minutes, Pb and PbS in copper dross slag enter gas under distillation
Phase, it is condensed to obtain lead bullion afterwards；Cu in copper dross slag2S, Cu are stayed in bottoms matte, so as in realizing copper dross slag
Copper is separated with lead.Chinese invention patent application publication No. 102373336A disclose it is a kind of separate refining lead produce in copper dross slag copper and
The method of silver, there is provided a kind of method that separation refining lead produces copper and silver in copper dross slag, refining lead is produced into copper dross slag is through reduction treatment
Solid alloy material, 5Pa is less than in pressure, 1100~1200 DEG C, is incubated 30~60min, 1400~1600 DEG C, is incubated 1~3h,
The volatile matter for obtaining is pb-ag alloy, and residue is copper alloy；Enter conventional lead smelting procedure using pb-ag alloy as raw material again
Or electrorefining operation, silver is enriched in the earth of positive pole, that is, be recycled silver；Copper alloy is in conventional manner directly as raw material
It is recycled metallic copper.
The present invention is with the appeal method identical studied of patent, the method for all employing vacuum distillation, but presence is permitted
Many crucial differences, first, the present invention directly carries out vacuum distillation concentration of valuable metals to many metal smelt slags of sulfur-bearing, are not required to
To be reduced using coke powder, simplify technological process；Second, particle diameter and shape of the present invention to the handled many metal smelt slags of sulfur-bearing
Shape do not require, without ball milling pretreatment or is reduced into solid material, and adaptability to raw material is strong；Third, experiment rule of the invention
Mould is the experimental size that 500Kg/ stoves are far longer than patent CN102676832A 2.5Kg/ stoves and patent 102373336A 20Kg；
Fourth, the present invention uses vacuum distillation fractional condensaion technology not only realizes lead bronze described in patent CN102676832A
Separate, also achieve the separation of metal and metal sulfide, and the present invention copper silver is not separated with specially
The copper silver of sharp 102373336A is separated larger difference.
To sum up, the present invention directly uses the method desulfurization enriching Cu silver antimony of vacuum distillation to many metal smelt slags of sulfur-bearing, will
Metal sulfide and metal carry out fractional condensaion, realize the separation of metal and metal sulfide, and lead and copper silver antimony point
From simplifying technological process.Both the effective rate of utilization and economic benefit of resource had been improve, the pollution to environment had been alleviated again, had
Have the advantages that to smelt that flow is short, environmentally friendly, working condition is good, meet the requirement of energy-conservation and clean manufacturing.
