Abstract
The present invention relates to new lead-antimony direct separating technology for jamesonite, which is the novel lead-antimony separation process. The present invention is characterized in that lead-antimony effective separation is realized by the selectivity volatilization of fine stibnite by a special catalytic action on the volatilization of stibnite by water vapour through the obvious physicochemical property difference of the stibnite (Sb2S3) and galena (PbS) under the condition of the existence of the water vapour on the basis of temperature control, and thus, fine lead ore and fine antimony ore are respectively produced. The present invention has the advantages of no alloy production, direct production of the fine lead ore and the fine antimony ore by one-step processing, no reagent consumption, simple technological process, low production cost and high comprehensive metal recovery rate.
Description
The plumbous antimony directly separating technology of jamesonite belongs to smelting field of nonferrous metal.
Jamesonite (Pb
4FeSb
3S
14) be the symbiotic complicated sulfuration mine of a kind of many metals, very abundant in the standing stock of China, be the important source material of extracting and reclaim antimony (Sb), plumbous (Pb), silver multiple valuable metals such as (Ag).The key problem in technology of handling this ore is that plumbous antimony is separated.Known treatment process is, at first jamesonite is carried out the oxidizing roasting desulfurization, the oxide compound calcining that obtains is carried out retailoring output lead antimony alloy thereupon, and then lead antimony alloy is carried out plumbous antimony separate (for example voloxidation method, high speed centrifugation partition method, vacuum distillation method etc.) output lead bullion and needle antimony respectively.This method not only Production Flow Chart is long, and complex process, production efficiency are low, and seriously polluted, metal recovery rate is low, plumbous antimony separating effect is undesirable.The present invention is directed to a plumbous antimony isolation technique difficult problem that exists in the jamesonite tradition smelting technology flow process, proposed a kind of new plumbous antimony separation method from new angle.
The difference of the present invention and known method is, not again plumbous antimony to be separated later at the output lead antimony alloy, but utilize the difference of various mineral compositions on physicochemical property in the jamesonite, directly jamesonite being carried out plumbous antimony separates, respectively output antimony concentrate and lead ore concentrate, and concentration of precious metal in lead ore concentrate, both realized effective separation of plumbous antimony, avoid the dispersion of precious metal again and improved the comprehensive recovery of metal, and do not consumed any reagent.Be effective ways, have wide prospect in industrial application with ground-breaking processing jamesonite.
The objective of the invention is to control the dividing potential drop of water vapour in the temperature of metallurgical process and the gas phase, directly jamesonite carried out plumbous antimony and separate, output antimony concentrate and lead ore concentrate respectively, and concentration of precious metal in lead ore concentrate.
The plumbous antimony directly separating technology of the jamesonite that the present invention proposes is based on controlled temperature and white antimony (Sb under the condition that water vapour exists is arranged
2S
3) and lead glance (PbS) have significant physicochemical property difference, utilize the special katalysis that volatilization showed of water vapour to white antimony, the selectivity volatilization by white antimony makes it separate with lead glance, thereby realizes effective separation of plumbous antimony.With this technology jamesonite is handled, can be distinguished output antimony concentrate and lead ore concentrate.
Technical qualification in the plumbous antimony sepn process:
1, temperature is 500～1000 ℃;
2, steam partial pressure 0.02～0.1MPa;
3,2～4 hours time.
Fig. 1 is a principle flow chart of the present invention.Jamesonite enters plumbous antimony sepn process through the granulation of getting the raw materials ready, and controlled temperature makes plumbous antimony be separated output lead ore concentrate and antimony concentrate respectively with steam partial pressure.Lead ore concentrate and antimony concentrate refine with traditional method.
The present invention compares with known technology and has the following advantages:
1, directly jamesonite is carried out plumbous antimony and separate output lead ore concentrate and antimony concentrate;
2, technical process is simple, only needs once the step processing plumbous antimony is separated, not output
Alloy, thus traditional jamesonite smelting technology is greatly simplified;
3, do not consume any reagent, easy and simple to handle, production cost is low.
