Abstract
The invention relates to a technology for producing Au and Ag from precious Pb by vacuum distillation. The technology is characterized by including the technical processes of vacuum distillation, oxidization for removal of Cu and Sn, extraction of Cu and Sn, extraction of Au, Ag, Pt and Pd, removal of As, secondary vacuum distillation, refining of Sb, and electrolyzation. The technology is simple; the equipment investment is less; Pb, Bi, Sb and As are directly extracted without redox; the recovery rate of rare valuable metal is high; the cost is low; the pollution is small; and the technology is a new smelting technology for noble metals of Au and Ag.
Description
Technical field
The present invention relates to a kind of Metal smelting method, gold and silver technology is produced in particularly a kind of precious metals containing lead vacuum distilling.
Background technology
The anode sludge retailoring of lead bullion electrorefining output gets precious metals containing lead, contains gold and silver 30%～50% in the precious metals containing lead, lead, bismuth, antimony 30%～50%, and copper 5%～10% does not wait.At present, isolating common process to metal in the precious metals containing lead is earlier with the precious metals containing lead oxidation refining, remove gold and silver all metal impurities in addition, obtain the alloy of gold and silver content more than 90%, further again electrolytic separation gold and silver, wherein lead, bismuth, antimony, arsenic, copper, tin are separated with the flue dust or the oxidation sludge mode of oxide compound, obtain these metals and again it is carried out retailoring, cause the loss of metal, energy dissipation, the while is contaminate environment also.
Summary of the invention
The objective of the invention is in order to overcome the weak point of above-mentioned technology, and provide a kind of production technique simple, lead, bismuth, antimony, arsenic do not need retailoring directly to extract, the metal recovery rate height, and cost is low, pollutes little precious metals containing lead vacuum distilling and produces gold and silver technology.
For achieving the above object, the concrete production method of the present invention's employing is as follows:
1, vacuum distilling: precious metals containing lead is placed in the vacuum distillation furnace, under 1000 ℃～1200 ℃ temperature, carry out vacuum distilling, realize separating fully of plumbous bismuth antimony arsenic alloy and gold and silver platinum palladium gun-metal.
2, oxidation copper removal tin: above-mentioned isolated gold and silver platinum palladium gun-metal is placed in the branch silver stove, be heated to and carry out oxidation blowing copper removal tin more than 1100 ℃ under the temperature, extract the gold and silver platinum-nickel alloys.
3, carry copper tin: adopt common process to extract copper, tin the copper scruff of above-mentioned output.
4, carry gold and silver platinum palladium: will adopt common process to extract gold and silver, platinum, palladium through the gold and silver platinum-nickel alloys that oxidation copper removal tin extracts.
5, arsenic removal: will add the iron arsenic removal after the fusion under 800 ℃～1000 ℃ temperature through the isolated plumbous bismuth antimony arsenic alloy of vacuum distilling, the plumbous bismuth antimony alloy of output.
6, vacuum second distillation: will place through the plumbous bismuth antimony alloy of above-mentioned arsenic removal output and carry out the vacuum second distillation in the vacuum distillation furnace and realize that plumbous, bismuth separates with antimony, extracts lead antimony alloy and bismuth antimony alloy respectively.
7, antimony refining: the lead antimony alloy of said extracted is carried out the antimony refining get antimony.
8, electrolysis: difference output lead, the bismuth-containing anode sludge after will carrying out electrolysis through the bismuth antimony alloy that the vacuum second distillation extracts.
The present invention is owing to adopt above processing method, and technology is simple, the equipment less investment, and lead, bismuth, antimony and arsenic do not need redox directly to extract, rare your recovery rate of valuable metals height, cost is low, pollutes for a short time, is gold and silver precious metal smelting novel process.
