Description
Technical field
The present invention relates to a kind of method of vacuum distilling desulfurization enriching Cu silver antimony from sulfur-bearing many Metal smeltings slag, belong to non-ferrous metal pyrometallurgy and vacuum metallurgy technology field.
Background technology
Sulfur-bearing many Metal smeltings slag is lead bullion liquation decoppering and the sulfur-bearing metallurgical slag adding sulphur copper removal process and produce.In liquation decoppering process, the reduction of the solubility with temperature of Cu in plumbous liquid and reducing, when plumbous liquid temp drops to below 1225K, the crystallization of precipitation is not fine copper, but containing the copper-lead sosoloid of Pb, it floats on plumbous liquid level with solid state.As simultaneously in lead bullion and Sb and Cu formation copper arsenic and copper-lead compound, and the impurity element such as nearly all Fe, Ni, Co, S, also float on plumbous liquid level because being insoluble to lead.Lead bullion is after liquation decoppering, and the copper remained in lead generally adopts the method removing adding sulphur copper removal, the Cu of formation
2s density ratio lead is little, is insoluble to again in lead, floats on plumbous liquid level in solid dross state.In sulfur-bearing many Metal smeltings slag, lead tolerance is very high but can not directly enter plumbous refinery practice, because the character of the impurity such as Cu, Ag, Sb, S, As, Fe, Ni, Co wherein to lead has a great impact, such as make its hardness increase toughness to reduce, erosion resistance weakens.Therefore sulfur-bearing many Metal smeltings slag otherwise processed is tackled, and the various valuable metal of synthetical recovery.
At present, sulfur-bearing many Metal smeltings slag generally adopts soda iron chip filter to process, to reclaim copper, lead and precious metal wherein.Conventional pyrogenic process recovery process also has reverberatory smelting method, blast-furnace method, converter smelting process, electric furnace smelting process.Wet processing has pickling process, ammonia leaching process and alkaline leaching.The lead bullion that pyrogenic process recovery process obtains returns refining, and copper matte regulus reclaims copper, and pyrogenic process recovery process energy consumption is high, long flow path, noble metal dispersion, and production cost is high.Wet recycling process produces a large amount of waste water, waste liquid, adds the cost of sewage disposal.In addition, sulfur-bearing many Metal smeltings slag lead skim that meeting output is a large amount of when leaching, carrys out difficulty greatly to liquid-solid decoupled band.
For method process sulfur-bearing many Metal smeltings slag of vacuum distilling, Chinese invention patent application publication No. CN102676832A discloses a kind of copper dross slag vacuum distilling separating copper and plumbous method, it provide a kind of copper dross slag vacuum distilling separating copper and plumbous method, copper dross slag is placed in vacuum environment, add reductive agent coke powder, pressure be 5-200Pa, temperature carries out fractionation by distillation 30-180 minute under being the condition of 900-1300 DEG C, Pb and PbS in copper dross slag enters gas phase under distillation, after condensation, namely obtain lead bullion; Cu in copper dross slag
2s, Cu stay in distillation residue matte, thus realize being separated of copper and lead in copper dross slag.Chinese invention patent application publication No. 102373336A discloses a kind of method being separated copper and silver in refining plumbous product copper dross slag, provide a kind of method being separated copper and silver in refining plumbous product copper dross slag, it is solid alloy material that refining lead is produced copper dross slag through reduction treatment, 5Pa is less than, 1100 ~ 1200 DEG C, insulation 30 ~ 60min at pressure, 1400 ~ 1600 DEG C, insulation 1 ~ 3h, the volatile matter obtained is pb-ag alloy, and resistates is copper alloy; Again pb-ag alloy is entered conventional plumbous smelting procedure or electrorefining operation as raw material, silver is enriched in the anode sludge, is namely recycled silver; Copper alloy, directly as raw material, is namely recycled metallic copper in conventional manner.
The present invention is identical with the method that appeal patent is studied, and all have employed the method for vacuum distilling, but there is the difference of many keys, one, the present invention directly carries out vacuum distilling concentration of valuable metals to sulfur-bearing many Metal smeltings slag, does not need to adopt coke powder reduction, simplifies technical process; Its two, the present invention is to the particle diameter of handled sulfur-bearing many Metal smeltings slag and shape not requirement, and without the need to ball milling pretreatment or be reduced into solid materials, adaptability to raw material is strong; Its three, experimental size of the present invention is the experimental size that 500Kg/ stove is far longer than patent CN102676832A2.5Kg/ stove and patent 102373336A20Kg; They are four years old, what the present invention adopted is the separation that vacuum distilling fractional condensation technology not only achieves the lead bronze described in patent CN102676832A, also achieve being separated of metal and metallic sulfide, and the present invention is not separated to copper silver and has been separated larger difference with the copper silver of patent 102373336A.
To sum up, the present invention directly adopts the method desulfurization enriching Cu silver antimony of vacuum distilling to sulfur-bearing many Metal smeltings slag, metallic sulfide and metal is carried out fractional condensation, achieves being separated of metal and metallic sulfide, and being separated of lead and copper silver antimony, simplify technical process.Both improve effective rate of utilization and the economic benefit of resource, alleviated again the pollution to environment, and had and smelt the advantages such as flow process is short, environmentally friendly, labor condition is good, meet energy-conservation and requirement that is cleaner production.
