Abstract
The invention provides a comprehensive recovery beneficiation method of tungsten/tin/zinc polymetallic ores. The method is characterized by comprising the following steps: the ores are crushed, grinded and reselected to obtain tungsten/tin/arsenic heavy-concentrate products; the flotation is performed for the heavy-concentrate products to obtain arsenic concentrates; flotation tailings are magnetically separated to obtain tungsten concentrates; magnetic separation tailings are tin concentrates; and the grinding and the flotation are performed for reselected tailings to obtain zinc concentrates. The method firstly performs the reselection to produce tungsten/tin/arsenic mixed concentrates, so that the flotation ore quantity and the flotation reagent dosage are reduced, and the advantages are provided to improve the tungsten/tin recovery rate and to reduce the scaling of a shaking table; and the arsenic flotation and the zinc flotation are separately performed, the types of flotation reagents are decreased, and the ore grinding cost is reduced.
Description
Technical field
The present invention relates to a kind of beneficiation method of nonferrous metals ore, particularly relate to a kind of tungsten tin zinc many metals synthetical recovery beneficiation combined method method, belong to nonferrous metals ore technical field of beneficiation.
Background technology
Tungsten tin mine association zinc arsenic class ore, except main tungsten, tin element, also can the multiple element such as synthetical recovery zinc, arsenic, ore mineral kind is more, between mineral occurrence characteristics and mineral, embedding cloth Relationship Comparison is complicated, and ore, based on disseminated, is secondly compact massive, various mineral disseminated grain size thickness is uneven, and Mineral separation difficulty is larger.
This type of ore deposit ore of current process mainly adopts (1) flotation---gravity treatment---magnetic separation process.That is: raw ore carries out flotation and selects sulphide ore after broken, ore grinding, and flotation tailing carries out gravity treatment again and reclaims tungsten tin bulk concentrate, high intensity magnetic separation separating tungsten, tin.The grinding particle size that this flow process requires due to flotation is thin, and not only power consume is high, and easily cause wolframite, cassiterite crosses pulverizing, affects the recovery of tungsten and tin; And causing the ore pulp amount of flotation operation large, floating agent consumption is large, increases production cost.(2) flotation---gravity treatment---floatation process, namely raw ore carries out flotation and selects sulphide ore after broken, ore grinding, and flotation tailing carries out gravity treatment again and reclaims tungsten tin bulk concentrate, FLOTATION SEPARATION tungsten, tin.This flow process is when---gravity treatment---magnetic separation process that there is flotation not enough, and also have when tungsten tin FLOTATION SEPARATION, the addition of medicament is comparatively large, and the acidity value of flotation is low, high to equipment requirement, and production cost is high.
Therefore, be necessary to explore and find the effective separation method of tungsten tin mine association zinc arsenic class ore, to improve the recovery of associated metal, reduce the consumption of floating agent simultaneously, energy-conservation, reduce production cost.
Summary of the invention
Object of the present invention is just to overcome prior art above shortcomings, for the problem lacking the effective separation method of tungsten tin mine association zinc arsenic class ore in prior art, after research and lot of experiments screen repeatedly, propose a kind of tungsten tin zinc many metals synthetical recovery beneficiation combined method method, the present invention can realize tungsten tin mine association zinc arsenic class ore and effectively be separated, synthetical recovery tungsten, tin, zinc and arsenic.
The technical solution that the present invention provides is: this tungsten tin zinc many metals synthetical recovery beneficiation combined method method, ore is carried out fragmentation, ore grinding, gravity treatment obtain tungsten tin arsenic heavy sand product, heavy sand product carries out flotation output arsenic concentrate, flotation tailing again magnetic separation obtains tungsten concentrate, and magnetic tailing is Tin concentrate; Gravity tailings is ore grinding, flotation output zinc concentrate again, has been characterized in following steps.
1. raw ore gravity treatment step comprises primary grinding, two sections of shaking tables.
Wherein primary grinding Task-size Controlling accounts for 55% at-0.075mm.
Two sections of shaking tables comprise one roughing and throw tail, shaking table stroke: 10 ~ 20mm, shaking table jig frequency: 280 ~ 300 min-1, laterally feedwater: 80 ~ 100mL/s, and feed launder feeds water: 35 ~ 45mL/s, the cross dip of shaking table: 2.2 ~ 2.8 degree; Primary cleaning, namely raw ore is thrown after tail through roughly selecting, chats is carried out scan the concentrate obtained merge with rougher concentration together with carry out the selected test of tungsten tin as shaking table to ore deposit, obtain tungsten tin gravity concentrate.Shaking table stroke: 10 ~ 20mm, shaking table jig frequency: 280 ~ 300 min-1, laterally feedwater: 70 ~ 80mL/s, feed launder feeds water: 30 ~ 40mL/s, the cross dip of shaking table: 2.2 ~ 2.8 degree.
Carry out arsenic flotation step at heavy sand product to comprise three times and roughly select, rougher concentration synthesis arsenic concentrate.Mine tailing is tungsten tin bulk concentrate.The adjusting agent of arsenic flotation is copper sulphate, and collecting agent is butyl xanthate, and foaming agent is terpenic oil, and flotation time is respectively 5 points, 4 points, 3 points.
The magnetic separation of tungsten tin bulk concentrate is separated and comprises two stages of magnetic separation.One section of low intensity magnetic separation concentrate is magnetic impurity, and magnetic field intensity is 0.1 – 0.12T; It is tungsten concentrate that weakly magnetic tailings carries out high intensity magnetic separation concentrate, and mine tailing is Tin concentrate.Magnetic field intensity is 1 – 1.2T.
Gravity tailings flotation selects zinc to comprise primary grinding, one roughing, triple cleaning, scan for twice.The mog of zinc flotation accounts for 80% for-0.075mm, thick, adopt lime adjustment slurry pH (13.2 ~ 13.8) when scanning, and copper sulphate is activator, thiourethane is collecting agent, it is 5 points that flotation time is roughly selected, and the selected time is respectively 3 points, 2 points, 2 points, and the time of scanning is respectively 3 points, 3 points.
Compared with prior art, the present invention adopts gravity treatment, and---------magnetic separation process beneficial effect is in the flotation that floatation process is more conventional---gravity treatment---in magnetic separation in flotation.
Avoid tungsten tin to cause pulverizing due to ore grinding, and affect tungsten tin and reclaim.
First gravity treatment output tungsten tin arsenic bulk concentrate, decrease flotation ore deposit amount thus reduce floating agent dosage, avoid the situation of first floating containing a large amount of calcium ion (flotation adds large quantities of lime) in ore pulp when entering gravity treatment more simultaneously, provide advantage for improving the tungsten tin rate of recovery and reducing shaking table fouling.
Arsenic flotation separates with zinc flotation, decreases floating agent kind and reduces ore grinding cost simultaneously.
