Abstract
In the lead electrolytic method, smooth electrodeposition lead is recovered by adding Noigen BN-1390 and/or Noigen BN-2560 to an electrolyte comprising lead and sulfamic acid in a concentration of 1 to 700 mg/L. Therefore, smooth electrodeposition lead can be recovered without setting a fluorine removing device.
Description
Technical field
The present invention relates to a kind of recovery and carry out the method for the Pb that contains in the dry type cigarette ash that the dry type stove of melt processed produced by recycling melting raw materials stoves such as non-ferrous metal metallurgy, base or electronic units and to trade waste.
Background technology
For the Pb that contains in the dry type cigarette ash that reclaims non-ferrous metal metallurgy, cigarette ash is carried out that sulfuric acid leaches and forms after the lead sulfate, in electric furnace, carry out smelting reduction.To isolated metal carries out alkaline purification by smelting reduction, then metal is carried out anode casting, by using the Betts method of in silicofluoric acid solution, carrying out electrorefining, reclaim Pb afterwards.
About the Betts method, for example in Japanese kokai publication sho 50-115120, disclose the electrolytic smelting method (patent documentation 1) of high purity lead, but, therefore in draining, needed fluorine to remove equipment because electrolyzer is a silicofluoric acid.
[patent documentation 1] Japanese kokai publication sho 50-115120: the electrolytic smelting method of high purity lead
Summary of the invention
At existing technology, purpose provides a kind of plumbous electrolysis process that fluorine removal equipment just can reclaim level and smooth galvanic deposit lead that need not to be provided with.In the present invention, by in thionamic acid, carrying out electrorefining, can be reclaimed as tabular galvanic deposit lead.
The present inventor has finished following invention in order to address the above problem.
(1) a kind of electrolysis process of lead, it adds Noigen BN-1390 and/or Noigen BN-2560 by press 1～700mg/L in electrolytic solution, thereby reclaims level and smooth galvanic deposit lead.
(2) in the mode of above-mentioned (1), become below the 100A/m2 by making current density, thereby reclaim level and smooth galvanic deposit lead.
According to the present invention, (1) has been found can easily obtain the method for the level and smooth galvanic deposit lead of galvanic deposit face by dropping into suitable additive in the electrorefining of lead.
Description of drawings
Fig. 1 represents the relation of the additive and the galvanic deposit state of the mode among the present invention.
Fig. 2 represents the galvanic deposit state in the embodiments of the invention 2.
Embodiment
Below, the present invention is described in more details.
Lead of the present invention as raw material contains thing, contains the following tin of the lead, 0.04mass% of 70～99mass%, the bismuth of 0～30mass%.
For example, above-mentioned lead is contained thing carry out anode casting, and use this anode to carry out electrorefining.By making the anodic size littler, can prevent fringing effect, and can reclaim level and smooth and good galvanic deposit lead than the size of negative electrode.
Have again,, can access more level and smooth galvanic deposit lead by adding thionamic acid with 20 to 100g/L.
In addition, as smooth agent, (ノ イ ゲ Application: a kind of nonionogenic tenside) BN-1390 and/or Noigen BN-2560 are 1～700mg/L, and making current density is 100A/m by making Noigen
2Below, preferred 50～100A/m
2, can reclaim level and smooth and good galvanic deposit lead as shown in Figure 1.
(embodiment 1) reclaims the method for level and smooth galvanic deposit lead
As the composition of electrolytic solution, in the solution after lead concentration is adjusted into 80g/L, thionamic acid concentration being adjusted into 20g/L, add the Noigen BN-1390 of 10mg/L as smooth agent.
Alternately pack in the electrolyzer as negative electrode with the lead anode of high Bi grade, lead electrode plate (negative plate) or with stainless steel plate.
Though the size of negative electrode is set at respect to about the big 20～30mm of anode, this is optimum to alleviating to the current concentration of edge part.
Pack into after the electrode, in electrolyzer, replenish electrolytic solution, and by being that mode about 1 hour is supplied solution according to electrolytic solution residence time in electrolyzer, thereby make the concentration distribution in the electrolyzer even.
The fluid temperature of electrolytic solution is adjusted to after 20～30 ℃, by with 100A/m
2Current density switch on, can reclaim level and smooth galvanic deposit lead.
(embodiment 2) reclaim the method for level and smooth galvanic deposit lead
As the composition of electrolytic solution, in the solution after lead concentration is adjusted into 80g/L, thionamic acid concentration being adjusted into 20g/L, add the NoigenBN-1390 of 400～700mg/L as smooth agent.
Alternately pack in the electrolyzer as negative electrode with the lead anode of high Bi grade, lead electrode plate or with stainless steel plate.
Though the size of negative electrode is set at respect to about the big 20～30mm of anode, this is optimum to alleviating to the current concentration of edge part.
Pack into after the electrode, in electrolyzer, replenish electrolytic solution, and by being that mode about 1 hour is supplied solution according to electrolytic solution residence time in electrolyzer, thereby make the concentration distribution in the electrolyzer even.
The fluid temperature of electrolytic solution is adjusted to after 20～30 ℃, by with 100A/m
2Current density switch on, can reclaim level and smooth galvanic deposit lead.
Claims (2)
1. the electrolysis process of a lead is characterized in that,
Add Noigen BN-1390 and/or NoigenBN-2560 by in electrolytic solution, pressing 1～700mg/L, thereby reclaim level and smooth galvanic deposit lead.
