Description
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%；
