Description
Technical field
The method that the present invention relates to a kind of to recycle Pb-Zn deposits object from high sulfur-lead-zinc ore tailing, belongs to Mineral Processing Engineering skill
Art field.
Background technique
High sulfur-lead-zinc ore is widely distributed, such as Huize, yunnan lead as a kind of common lead-zinc deposit type in China
Zinc ore, Yiliang Pb-Zn deposits, billows deep blue Pb-Zn deposits, Fankou Lead-zinc Deposit, Guangdong, Qixia Hill In Nanjing Pb-Zn deposits, Hunan Shuikoushan Lead-zinc Mine etc.
Extremely typical high sulfur-lead-zinc ore is belonged to, the content of iron sulfide mineral is usually higher in this kind of ore, up to 30% or more, has
A little even as high as 50% or more；In addition, lead zinc grade and lead zinc oxygenation efficiency are higher in this kind of ore, Pb+Zn grade is logical in ore
15% or more Chang Keda, as the grade of Pb+Zn in Yunnan Huize Pb-Zn, Yiliang Pb-Zn deposits has reached 25% or more.However, by
Pyrite content is high in ore, for the grade for improving lead and zinc concentrate, needs to have used a large amount of lime in raw ore floatation process
To inhibit pyrite.A large amount of uses of lime are also easy to in ore pulp though stronger inhibiting effect can be generated to pyrite
Galena, zincblende and the association rare precious metal mineral of microfine generate inhibiting effect, influence lead zinc and association rare precious metal etc.
The recycling of mineral causes Pb, Zn content in tailing excessively high, as the content of lead zinc in Huize Lead-zinc Mine tailing may be up to 0.81 ~
1.1%, 2.5 ~ 3.2%, the loss of lead zinc is serious.
Further, since the content of the sulfide minerals such as galena, zincblende, pyrite is higher in ore, mineralizing process chats
Geochemistry process between object is more strong, and it is white for leading to the sulfide minerals oxidation alteration such as part galena, zincblende in ore
The oxide minerals such as lead ore, smithsonite, smithsonite.However, the recovery process process due to lead Oxide ores of zinc is complex, big portion
Divide high sulfur-lead-zinc ore to select the recycling for not accounting for the oxide minerals such as lead zinc in the mineral processing circuit of factory, causes a large amount of lead zinc
Mineral loss is in tailing.
Therefore, in the removal process of high-sulfur Pb-Zn tailings, emphasis is needed to consider the work of two aspects: first is that micro- in tailing
The recycling of particulate lead-zinc sulphide minerals；Second is that in tailing lead Oxide ores of zinc recycling.In these areas, although doing both at home and abroad
A large amount of research, but since tailing physical property is special, selects process sludge serious interference, reagent cost height, process flow complexity again etc.
Factor causes selecting again for high sulfur-lead-zinc ore tailing to be difficult to obtain preferable sorting index and be difficult to realize industrial application.As opened
Jin Min has invented a kind of Pb-Zn tailings recoverying and utilizing method (Zhang Jinmin Pb-Zn tailings recoverying and utilizing method [P] again again
Chinese patent: 201210220652.7), in the invention using the concentrated sulfuric acid and sodium chloride saturated solution to Pb-Zn tailings into
Row hydrometallurgic recovery can recycle the metals such as lead, zinc, silver simultaneously, but due to the Pb-Zn tailings enormous amount that China generates every year, and soak
Process is the progress equipment seriously corroded in strong acidic environment out, and there are still certain offices in terms of industrial application for the technology
Limit.Ma Yue et al. has invented the method for Pb-Zn tailings comprehensive recovery of lead zinc a kind of, and (a kind of Pb-Zn tailings of the such as Ma Yue, Li Wei are comprehensive
Close method [P] Chinese patent of recycling lead zinc: 201610670115.0), this method is first classified Pb-Zn tailings ,+
The coarse grain of 0.074mm carries out preenrichment using spiral chute, and the fine fraction of -0.074mm carries out bulk flotation, then again by spiral
The concentrate of chute carries out ore grinding after merging with the concentrate of bulk flotation, carries out roughing, selected and scan after regrinding again, final to obtain
Lead and zinc bulk concentrate.Although the invention lead zinc recovery is higher, due to using the process integrations such as screening, gravity treatment, flotation, work
Skill process is complicated, and the concentrate finally obtained is lead and zinc bulk concentrate, it is difficult to real lead zinc efficiently separates, added value of product compared with
It is low.Feng Zhongwei etc. Guizhou Pb-Zn tailings have been carried out lead zinc sulphur in tailing comprehensive recovery experiment (Feng Zhongwei, Ning Fatian,
Lan Guimi, waits synthetical recovery [J] metal mine of lead zinc sulphur in the Pb-Zn tailings of the Guizhou, and 2009, (394): 157-
160), using the mixed floating concentrate zinc sulphur content of the preferential bulk flotation-of sulphide ore from the technique recycling tailing of-lead oxide ore sulfide flotation
The mineral such as lead zinc sulphur, achieve preferable sorting index, and the final grade and the rate of recovery for aoxidizing lead in lead concentrate reaches respectively
48.56% and 85.38%, but the process flow is primarily directed to the recycling of lead oxide mineral in tailing, to zinc oxide in tailing
Recovering effect it is poor.Therefore, how on the basis of original process flow and equipment, lead zinc in high sulfur-lead-zinc ore tailing is carried out
The high efficiente callback of equal mineral, is still one of the main bugbear that mineral manufacture field faces.
Summary of the invention
The method that the object of the present invention is to provide a kind of to recycle Pb-Zn deposits object from high sulfur-lead-zinc ore tailing, with traditional elder generation
The Pb-Zn tailings of flotation select the technique different again again for desliming, and the present invention is according to the embedding cloth of the mineral such as lead zinc in high sulfur-lead-zinc ore tailing
The physical property feature of feature, enrichment discipline and tailing preferentially carries out flotation recovery to the microfine lead minerals in high-sulfur Pb-Zn tailings,
Loss of the micro-size fraction Pb-Zn deposits object in desliming process is reduced, and roughing and scans the different collecting of use in zinc floatation process
Agent type can reduce sludge to the adverse effect of zinc flotation, the synchronous grade and the rate of recovery for improving zinc concentrate.
The present invention is realized by following technical scheme: a method of recycling Pb-Zn deposits object from high sulfur-lead-zinc ore tailing,
