Abstract
Bismuth-silver-zinc-containing shell vacuum extraction silver, bismuth and zinc are that a kind of employing vacuum metallurgy separation of tertiary alloy bismuth-silver-zinc-containing shell makes it directly to obtain thick silver, thick bismuth and crude zinc.Bismuth-silver-zinc-containing shell is the product that bismuth refining zincification removes silver process, this material adds in the vacuum distillation furnace after melting, temperature is at 910 to 1120 ℃ in the control stove, vacuum tightness is at 26～53 crust, zinc and bismuth evaporate successively, and condensation on condenser, obtaining thick bismuth, crude zinc, silver does not evaporate basically and becomes grade at rich silver alloys more than 50% or thick silver.This method technical process is brief, and metal separation is thorough, and the oxide compound of no bismuth and zinc produces, and metal direct yield height has been eliminated environmental pollution basically.It is the Perfected process of separation, purification ternary alloy.
Description
Bismuth-silver-zinc-containing shell vacuum extraction silver, bismuth and zinc are a kind of non-ferrous extractive metallurgy methods.
Bismuth-silver-zinc-containing shell is the product that bismuth refining zincification removes silver process, and after the desilver of bismuth refining zincification, residual silver seldom can reach specified standards in the bismuth, and silver then is enriched in the bismuth-silver-zinc-containing shell.
In order to extract silver from the bismuth cadmia, two kinds of existing methods are a kind of to be that distillation dezincifies, and technical process is shown in Figure of description 1.This method long flow path consumes zinc, and product only arrives thick bismuth, thick silver, the anode sludge.Second kind is wet dezincification, and technical process is shown in Figure of description 2.This method can not reclaim zinc with the metal shape, and bismuth zinc long flow path is extracted in the back.So the flow process of the processing bismuth-silver-zinc-containing shell of current use is all undesirable.
The objective of the invention is to adopt the method for vacuum distilling that the ternary alloy of being made up of bismuth, silver, three valuable metals of zinc is separated, once obtain thick silver, thick bismuth and crude zinc respectively.
Main contents of the present invention are partly formed by following five:
1. principle: three kinds of metals in the bismuth-silver-zinc-containing shell ternary alloy, under certain temperature and vacuum tightness, steam is pressed with marked difference, and the vapour pressure of silver is minimum, can think and not evaporate basically; Bismuth takes second place and can evaporate in a large number; The zinc maximum can complete evaporation.
The applicant is in application number is 87209402 patent application, the multistage continuous still battery vacuum oven of a kind of internal heat type is disclosed, can successful application come separating binary alloy (as tin, lead alloy etc.), the present invention through improving, equally successfully separates bismuth silver zinc on original basis.Its structure is shown in Figure of description 4, and the alloy of fusing enters in the vacuum oven, by can reach the purpose of three metal separation to the control of temperature and vacuum tightness, according to certain schedule of operation;
2. technical process and condition
Technical process is shown in Figure of description 3.Handled raw material composition is as follows:
Bismuth (Bi) zinc (Zn) silver (Ag) tin (Sn) arsenic (As)
70～80% are not more than 13% is not less than 1%＜0.20＜0.2%
Plumbous (Pb) copper (Cu)
0.58 about about 0.5%.
Raw material is placed charging pot, intensification, steaming empty stove simultaneously also heats up, and charge into rare gas element and prevent the raw material oxidation, after treating the alloy melting in the charging pot, this moment, the vacuum oven temperature rose to 1000 ℃, get rid of the rare gas element in the vacuum oven, start vacuum system, alloy promptly enters in the vacuum oven via feed-pipe (1) from the charging pot.Temperature is 26～52 crust 900～1120 ℃ of vacuum tightnesss in the control stove, zinc and bismuth evaporation, zinc condensation on outermost layer condensation cover, bismuth condensation on internal layer condensation cover, liquid crude zinc and thick bismuth go out zinc pipe and get rid of by going out bismuth, the alloy of Fu Yin remains in the evaporating pan (2), process is successively carried out, and rich silver alloys is got rid of continuously through (5), and its silver content is not less than 50%.Perhaps be interrupted operation, treat that promptly the rich silver alloys of dish in (2) gathers blowing out after the some amount, takes out thick silver from dish.
Also can in a discharge nozzle, discharge the bismuth zinc alloy continuously, get rid of rich silver alloys in another pipe continuously according to material condition and customer requirements.
3. embodiment
Raw material composition: bismuth 70.09%, zinc 12.89%, silver 5.63%, lead 0.85%, copper 0.5%, tin 0.18%, arsenic 0.15%
Processing condition: applying argon gas protection in the stove, 1000 ℃ of vaporization temperatures, vacuum tightness 30 crust.
Output object: thick bismuth grade 91%, crude zinc grade 60%, thick silver-colored grade 60%.
4. the advantage that compared with prior art has:
(1) can directly obtain once the alloy that bismuth, silver, zinc three are respectively main body. Rich silver alloy can be used as the raw material that electrolysis is extracted fine silver, and the further processing of thick bismuth, crude zinc or warp can obtain simple metal separately; Perhaps return last procedure, directly reclaim as the additive of zinc desilverization.
(2) oxide of no bismuth and zinc produces, the direct recovery rate height of metal.
(3) filter of non-environmental-pollution, working condition is good.
(4) process is carried out continuously and automatically, and labour intensity is very low.
(5) energy consumption is not high, processes one ton of bismuth cadmia, about 1000 degree of power consumption.
5. description of drawings
Accompanying drawing 1: existing vacuum distilling dezincification flow process.
Accompanying drawing 2: existing wet dezincification flow process.
Accompanying drawing 3: flow process of the present invention
Accompanying drawing 4: the multistage continuous still battery vacuum oven of internal heat type
Wherein: 1-feed-pipe 2-multistage evaporation dish 3-condensation cover
