Slag former is added in body, stirs evenly；Wherein, the slag former is sodium nitrate and sodium hydroxide or sodium carbonate and silicon
Stone；Controlling furnace temperature is 800-900 DEG C, and injection tube importing compressed air is inserted into melt and carries out inserting to blow making scruff, often inserts and blows 3-
5 hours fish out a scruff, until < 1wt% stanniferous in melt；
(2) volatilize de- antimony
Control furnace temperature be 600-700 DEG C, by injection tube in step (1) after detin bath surface blowing pressurized air into
Row, which volatilizees, takes off antimony, obtains antimony oxygen powder；Period constantly claws dross, the 4wt% of < containing antimony in melt after detin；
(3) liquation decoppering
Furnace temperature slow cooling is subjected to liquation decoppering to the melt after antimony is taken off in step (2) to 400 DEG C -550 DEG C, after copper removal
Melt from reverberatory furnace put lead mouth release after send vacuum drying oven be enriched with silver metal.
Wherein, described containing lead content in the high tin copper master alloy of antimony be 42-60wt%, antimony 13-18wt%, tin 10-
20wt%, copper 10-15wt%, silver 0.3-1.5wt%.
Preferably, the process of step (3) liquation decoppering are as follows: the melt after antimony de- in step (2) to be cooled to
At 500-550 DEG C, fishing is gone for the first time except copper ashes, and fishing is gone for the second time except copper ashes when temperature is down to 400-500 DEG C.
Preferably, the flow of compressed air is using during injection tube blowing pressurized air in the step (1)
100-300Nm3/h。
Preferably, the flow of compressed air is using during injection tube blowing pressurized air in the step (2)
1500-3000Nm3/h。
The beneficial effects of the present invention are:
(1) present invention is handled the high tin copper master alloy containing antimony using pyrogenic process, is successively decreased step by step on earth using temperature by height
Successively Separation of Tin, antimony and copper, oxidation make scruff opened a way to tin, low temperature volatilization antimony is collected in the form of antimony oxygen powder, with
Liquation decoppering mode collects copper, silver is then trapped in lead bullion, compares and is handled using wet process, process flow is short, technique
Upper to be easy to implement, process design is reasonable, economic and practical, has biggish application value.
(2) present invention oxidation makes to take in scruff step and carries out inserting to blow in injection tube insertion melt making scruff, is blown by inserting
So that slag making is more complete, detin rate is improved；It and is then to take injection tube to bath surface carry out table spray in de- antimony step of volatilizing
The de- antimony of volatilization is blown, the mode of surface blowing containing sb oxide volatilization faster, to improve the rate volatilized containing sb oxide.This
Invention by insert blow makes scruff, surface blowing is volatilized de- antimony, process cycle can be effectively shortened, and then reduce production cost.
