Description

A kind of separation method of high-As and high-S tin rough concentrate
Technical field
The present invention relates to technical field of beneficiation, more particularly, to a kind of separation method of high-As and high-S tin rough concentrate.
Technical background
As China's placer tin ore resources gradually reduce, stannum-contained multi-metal sulphide ore becomes the main source of tin.However, such The universal sulfur content of tin resource is higher, and sulphide ore floatability differs greatly, and ore properties are sufficiently complex, causes Tin concentrate sulphur arsenic etc. miscellaneous Prime element content be difficult to meet Tin concentrate quality standard (YS/T 339-2011): tin grade > 40%, sulfur grade < 1.20%, The requirement of arsenic grade < 0.80%.Tin product selling price is not only influenced, it is unfavorable also to cause for subsequent smelting deep processing.
Currently, tin rough concentrate separation method mainly has gravity treatment, flotation and floating-weight process integration, selecting process is gradually Develop towards efficient, easy direction, selects factory rules and regulations mould enlarged, production management fining.Significantly, since tin-polymetallic Sulphide ore takes different degrees of inhibition in preamble sulphide ore sorting operation, for sulfoarsenic minerals such as pyrite, mispickel, therefore Suppression sulfoarsenic mineral how is solved, is the key that floatation desulphurization.
Zhao Shu (thick Tin concentrate dressing process research and industrial production relevant issues are inquired into, " mineral products comprehensive utilization ", and 2011 (05): 48-52. it) has studied and " floating-weight-magnetic " and " weight-magnetic-is floating " process flow processing tin rough concentrate is respectively adopted, although obtaining Preferable expanding test index, but technique is related to multiple ore grinding, process is tediously long, and cumbersome, inconvenience promotes and applies.
Flat good fortune first (comprehensive recovery experiment of old factory's tin rough concentrate association tungsten sulphur, " Modern Mineral ", 2014,30 (08): 34- 36+39.) have studied the process flow of use " ore grinding-floats sulphur-fubai tungsten " synthetical recovery sulphur, tungsten and tin from tin rough concentrate.By Used waterglass to size mixing in the technique, sulphide mineral flotation removing be not thorough, in addition float Tungsten tailing (as Tin concentrate) not into Row deep processing processing, causes Tin concentrate sulfur grade exceeded, for tin grade less than 30%, synthetical recovery index is undesirable.
Therefore, developing a kind of separation method for high-As and high-S tin rough concentrate and reaching Tin concentrate quality criteria requirements has Important research significance and economic value.
Summary of the invention
It is tediously long that there are processes it is an object of the invention to overcoming the separation method of tin rough concentrate in the prior art, operates numerous Trivial, inconvenience promotes and applies, and synthetical recovery index undesirable defect or deficiency provide a kind of separation of high-As and high-S tin rough concentrate Method.The present invention is using " floating-weight " process integration, and separation obtains Tin concentrate and tin time concentrate, separating technology from tin rough concentrate Simply, tin product structure is reasonable, and Tin concentrate sulphur arsenic is met the requirements of the standard.
In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical scheme:
A kind of separation method of high-As and high-S tin rough concentrate, includes the following steps:
S1: prescreening ore grinding: after tin rough concentrate prescreening, oversize repeats ore grinding-screening operation, until tin is thick Concentrate is -0.25mm grade;
S2: it sizes mixing: tin rough concentrate obtained by S1 is modulated to ore pulp, and it is 5~6 that regulator, which is added, to adjust pH;The ore pulp Concentration is 28~32%;
S3: 80~100 g tons of activator, 100~120 g tons of collecting agent, foaming agent FLOTATION SEPARATION: are added into ore pulp 20~30 g tons are done one roughing;Be added 30~40 g tons of collecting agent, 10~20 g tons of foaming agent do once purging selection;It is added 20~30 g tons of collecting agent, 10~15 g tons of foaming agent do secondary scan;It is selected that roughing foam does blank three times;Obtain sulphur essence Mine and floating sulphur tailing;
S4: Gravity separation: doing shaking table roughing for floating sulphur tailing, obtains Tin concentrate, medium tin ore, tailing and tin time concentrate, so Shaking table is made to medium tin ore afterwards to scan, and is obtained Tin concentrate, tin time concentrate and tailings, is respectively scanned shaking table roughing and shaking table Tin concentrate, tin time concentrate and tailings are corresponding to be merged, and Tin concentrate, shaking table tin time concentrate and shaking table tailing are obtained;
S5: FLOTATION SEPARATION: being milled to -0.074mm for shaking table tailing and account for 85%, controls pulp density 28~32%, successively plus Enter 80~120 g tons of Inorganic regulator, 70~110 g tons of supplementary catching agent, 500~700 g tons of collecting agent, foaming agent 15 ~25 g tons are done one roughing;25~35 g tons of supplementary catching agent, 180~220 g tons of collecting agent, foaming agent 8~12 is added G ton do once purging selection;15~25 g tons of supplementary catching agent of addition, 120~180 g tons of collecting agent, 8~12 grams of foaming agent/ Ton does secondary scan;It is selected that roughing foam does blank three times;Floating Tin concentrate and floating tailing are obtained, floating Tin concentrate is incorporated to tin time essence Mine.
The present invention uses prescreening-closed circuit grinding, not only effectively prevents easy cross of cassiterite and crushes, but also ensure that pozzuolite Mineral floating removes feed particle size;Using the floatability difference between pyrite, mispickel and cassiterite, in acidic environment, use Activator activates sulfoarsenic mineral, removes sulfoarsenic mineral by flotation, effectively reduces Tin concentrate sulphur arsenic excessive problem;Pass through Multistage shaking table sorts and tin-lead soldering, keeps Tin concentrate and tin time concentrate product structure distribution more reasonable.
The Tin concentrate tin grade that beneficiation method of the invention obtains is greater than 45%, the tin rate of recovery and is greater than 85%, tin time concentrate Tin grade is greater than the technical indicator that 4%, the tin rate of recovery is greater than 11%, and Tin concentrate sulphur arsenic meets the quality standard requirement.
Preferably, it is sieved in S1 using 0.25mm sieve.
