Description

The production method of high purity lead
Technical field
The present invention relates to plumbous smelting process, relate in particular to the production method of high purity lead.
Background technology
The main raw material of producing high purity lead at present is a concentrate of lead sulfide ore, and the general composition of concentrate of lead sulfide ore is: lead 40~75%, and zinc 1~10%, sulphur 16~20% also often contains association or associated metals such as silver, copper, iron, arsenic, antimony.The plumbous purity of high purity lead is 99.994%-99.999%.As shown in Figure 1, the traditional technology of producing high purity lead from concentrate of lead sulfide ore is: earlier with the concentrate of lead sulfide ore pyrometallurgical smelting, remove desulfuration, slag etc., obtain the lead bullion piece, remove copper then, add star metal again, positive plate, wet method electrolysis production high purity lead are made in casting.The wet method electrolysis process requires the antimony content of positive plate between 0.35%-0.8%, and copper content is not higher than 0.05%.The problem of the existence of this technology is: need to add absorption and the collection that star metal is beneficial to the anode sludge, increased process procedure and production cost.
The store battery consumption of lead accounts for significant proportion in the consumption of lead, so waste and old lead acid accumulator is the main raw material of secondary lead.As shown in Figure 2, the technology of producing lead bullion from waste and old lead acid accumulator is: disassemble the waste and old lead acid accumulator of recovery, separate its plastic casing, acid solution obtains the used and scrapped battery lead plaster; Lead plaster is sent in the smelting furnace, and furnace temperature rises to 1100 ℃, and molten bullion separates because of difference of specific gravity with waste, plumbous melt cast regeneration lead bullion piece; The lead bullion piece of will regenerating is sent in the smelting furnace, adds the SODIUMNITRATE oxidation at 750 ℃ and removes impurity such as antimony, iron, is cooled to 350 ℃ of adding red phosphorus Celsius and removes copper again, obtains the lead bullion of purity 99.98%.The problem that this technology exists is: exist and remove the antimony process procedure, increased production cost; Adopt this technology from waste and old lead acid accumulator, to make lead bullion and have economic rationality, if make high purity lead then need adopt the wet method electrolysis process, and do not contain associated metals such as gold and silver in the secondary lead, consider to lack feasibility from the cost angle, therefore waste and old lead acid accumulator can not be as the starting material source that produces high purity lead in production reality, only can produce lead bullion, so traditional technology has hindered plumbous regeneration.
Summary of the invention
The technical problem to be solved in the present invention provided that a kind of technical process is simple, production cost is low, enlarge starting material source, the metal properties that reappears secondary lead of producing high purity lead, help improving the novel method of production high purity lead of the recovery utilization rate of secondary lead.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
(1) the concentrate of lead sulfide ore sulphur removal is restored smelting and be primary lead bullion piece;
(2) disassemble waste and old lead acid accumulator, get the used and scrapped battery lead plaster, the lead plaster melting is regeneration lead bullion piece;
(3) antimony content in above-mentioned primary lead bullion piece of analysis and the regeneration lead bullion piece, the 0.35%-0.8% that accounts for the lead gross weight by antimony content carries out proportioning to primary lead bullion piece and regeneration lead bullion piece, send into smelting furnace after preparing 450 ℃ of-600 ℃ of meltings, then furnace temperature is reduced to 330 ℃-350 ℃, add the red phosphorus copper removal, be not higher than 0.05% to copper content, molten bullion;
(4) above-mentioned molten bullion is cast into positive plate and carries out the wet method electrolysis, make high purity lead.
The present invention utilizes primary lead bullion piece need add the high characteristic of antimony content in the just suitable electrolysis of star metal, the regeneration lead bullion piece, the technology of primary lead being produced high purity lead and Production of Secondary Lead lead bullion unites two into one, and primary lead bullion piece carries out proportioning with regeneration lead bullion piece by antimony content and produces high purity lead.At first, the present invention can solve the difficult problem that primary lead bullion piece need not to add star metal, regeneration lead bullion piece need not to remove antimony and produce high purity lead, optimizes traditional technology, reduces technical process, saves the antimony resource; Secondly, the present invention is with secondary lead proportioning primary lead, make lead content and reach 99.994% high purity lead, the metals such as gold and silver that do not influence association in the primary lead of proportioning adsorb in the anode sludge, make the present invention have economic rationality, enlarge the starting material source that produces high purity lead, improved the recovery utilization rate of lead acid cell secondary lead, reached the purpose of reappearing the secondary lead metal properties fully.
