Abstract
The invention discloses a kind of dressing method of polymetallic ore, it is related to technical field of beneficiation, including raw ore is divided into the ore of three grades；4mm~+2mm grades ore is sorted by one-level gravitational separation equipment, is obtained the mine tailing that one-level mine tailing sorts as first paragraph and is lost tail；One-level concentrate is ground, is sorted by two grades of gravitational separation equipments, obtains grinding again after two grades of mine tailings merge with one-level chats, by flotation and the sorting of three-level gravitational separation equipment, the mine tailing that three-level mine tailing sorts as second segment is obtained and loses tail；2mm grades ore is sorted by gravitational separation equipment, is obtained mine tailing as the mine tailing of the 3rd section of sorting and is lost tail.Compared with prior art, the present invention loses tail by segmentation, reduces the gangue amount during follow-up sort, and tailings grade is lost in effectively control, and reduction sorts energy consumption and medicine consumption 5% or so.
Description
Technical field
The present invention relates to technical field of beneficiation, tail dressing method is lost in especially a kind of segmentation of polymetallic ore.
Background technology
During mineral are sorted, in order that valuable mineral is enriched with, it is necessary to be gone to non-target minreal i.e. gangue
Remove, and then form mine tailing.Ore dressing plant sets longer Beneficiation flowsheet in order to obtain meeting the concentrate of smelting requirements, generally to ore
Constantly it is enriched with, is sorted especially for the relatively low ore of head grade, the flow sorted is longer, flowage structure is more
It is complicated.In Beneficiation flowsheet, ore is needed by the grinding of milling medium, the effect of floating agent or some other depleting substance
With the process of electric energy, flow to sort number of times more, consume bigger, and gangue is during circulation is sorted, not only to purpose ore deposit
The enrichment of thing causes influence, and increases material consumption and energy consumption.
Dachang, Guangxi tin-polymetallic sulphide ore is a kind of complicated many mineral, many metal associations or the ore of symbiosis, property
Complexity, technique of preparing personnel are studied property and ore grinding, the beneficiation method of mineral, by raw ore be divided into+4mm grades ,-
4mm~+2mm grades, the ore of -2mm grades, are sorted to the ore of size fractionated, with Beneficiation flowsheet extension, sort
The increase of number of times, the circulation of gangue on stream so that follow-up sorting result is poor, and energy consumption and medicine consumption are high, cost accordingly increases
Plus, the overall efficiency lifting of influence enterprise.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of dressing method of polymetallic ore, to solve polymetallic ore
Gangue internal circulating load is big in Beneficiation flowsheet, the problem of energy consumption and medicine consume high.
In order to solve the above problems, the technical solution adopted by the present invention is：The dressing method of this polymetallic ore, including it is right
Raw ore carries out sieve classification, is divided into+4mm grades, -4mm~+2mm grades, the ore of -2mm grades, obtained+4mm grade ore deposits
Stone repeats grind, sieve, and iterative cycles are until all -4mm of ore grain size；It is further comprising the steps of：
A, -4mm~+2mm grades ore are sorted by one-level gravitational separation equipment, and one-level essence is obtained according to grade sorting
Ore deposit, one-level chats and one-level mine tailing, the mine tailing that the one-level mine tailing is sorted as first paragraph lose tail；
B, the one-level concentrate ground, sorted by two grades of gravitational separation equipments, obtain second concentrate and two grades of mine tailings,
The second concentrate is as concentrate product, and two grades of mine tailings are ground again after merging with the one-level chats, by flotation and three
Level gravitational separation equipment is sorted, and obtains three-level concentrate and three-level mine tailing, the three-level concentrate is used as concentrate product, the three-level tail
The mine tailing that ore deposit is sorted as second segment loses tail；
C, -2mm grade ore are sorted by gravitational separation equipment, obtain concentrate and tailings, the concentrate as concentrate product,
The mine tailing loses tail as the mine tailing of the 3rd section of sorting.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
Raw ore is sieved into+4mm grades, -4mm~+2mm grades, three grades of -2mm grades ore by the present invention, to difference
Grade ore carry out segmentation and sort, take each section sort after lose tail, tail is lost by segmentation, during reducing follow-up sort
Gangue amount, can effectively control to lose tailings grade, reduction sorts energy consumption and medicine consumption 5% or so.
Brief description of the drawings
Fig. 1 is the process chart of the embodiment of the present invention.
Embodiment
With reference to specific embodiment, the invention will be further described：
A kind of dressing method of polymetallic ore, its technological process are as shown in figure 1, including carrying out sieve classification to raw ore, divide
Into+4mm grades, -4mm~+2mm grades, -2mm grades ore, obtained+4mm grades ore repeats grind, sieve, repeatedly
Circulation is until all -4mm of ore grain size；It is further comprising the steps of：
A, -4mm~+2mm grades ore are sorted by one-level gravitational separation equipment, and one-level essence is obtained according to grade sorting
Ore deposit, one-level chats and one-level mine tailing, the mine tailing that one-level mine tailing is sorted as first paragraph lose tail；
B, one-level concentrate ground, sorted by two grades of gravitational separation equipments, obtain second concentrate and two grades of mine tailings, two grades
Concentrate is ground again as concentrate product, two grades of mine tailings after merging with one-level chats, is divided by flotation and three-level gravitational separation equipment
Choosing, obtains three-level concentrate and three-level mine tailing, three-level concentrate is as concentrate product, and the mine tailing that three-level mine tailing is sorted as second segment is lost
Tail；
C, -2mm grade ore are sorted by gravitational separation equipment, obtain concentrate and tailings, the concentrate as concentrate product,
The mine tailing loses tail as the mine tailing of the 3rd section of sorting.
Che He ore dressing plants are sorted to tin-polymetallic sulphide ore using the dressing method of the polymetallic ore, are lost by segmentation
Tail, reduces the gangue amount during follow-up sort, and can effectively control to lose tailings grade, reduction sorts energy consumption and medicine consumption 5% or so.
The present invention is suitable also for sorting for other nonferrous metals ores, such as bauxite, manganese ore.
