Description
Technical field
The present invention relates to a kind of mineral floating technical field, for the FLOTATION SEPARATION process of metalliferous mineral, nonmetallic mineral,
It can be used for the selected FLOTATION SEPARATION process of coal.
Background technique
Flotation technology is one of most common technology in mineral processing technology, using wide in global mineral processing technology
It is general.Flotation technology is the difference based on mineral grain Yu gangue particle surface nature, is carried out to gangue or mineral particle surface
After hydrophobic treatment, the particle of mineral or gangue is floated using the buoyancy of bubble, to realize gangue and minerals separation.
In the floatation process of mineral, the flotation of oxide ore coarse granule lean intergrowth is always a problem, flotation side
Method and equipment are always the primary study object of global mineral processing technology personnel.
Existing method for floating is that collecting agent and foaming agent, foaming agent and collecting agent knot are added in flotation raw ore slurry
It closes, collecting agent then passes to air in conjunction with mineral perhaps gangue and generates bubble mineral or gangue floating, mineral floating
Belong to direct flotation, gangue floating is belonged to reverse flotation.
No matter direct flotation or reverse flotation are completed in flotation unit, and flotation unit is mainly mechanical stirring inflation or inhales
Gas flotation cell, flotation column, microfoam flotation tank etc..
The flotation of oxide ore coarse granule lean intergrowth is always a problem.Because of the collecting agent that oxide ore direct flotation uses
Mostly fatty acid salt, collecting agent and the binding force of oxide ore are related with the-number of metal ion dew point by particle surface energy, and thin
Grain surface can be larger, and combining in collecting agent has advantage in competition；High-grade ore composition granule surface metal ion dew point is more, is catching
Receiving agent and combining also has advantage in competition.Coarse granule lean intergrowth surface energy is low, metal ion dew point is few, combines in collecting agent
It is in a disadvantageous position in competition, thus floating of the coarse granule lean intergrowth in flotation unit directly affects the rate of recovery of metal.
Under normal circumstances, in order to improve metal recovery rate, need to ore particle carry out depth dissociation, by improve grinding fineness come
Realize more mineral floatings.The raising of grinding fineness considerably increases ore grinding energy consumption and beneficiation cost.
The flotation unit that oxide ore flotation uses at present is conventional flotation cell.
The first existing floatation equipment is mechanical stirring inflation or induced air floatation slot, that is, traditional flotation cell, this
Kind flotation cell is the mainstream of flotation equipment, and the dressing plant in the whole world 90% still uses this traditional flotation cell, the reason is that this flotation cell
Belong to the flotation cell being used in series, operation is easy to grasp after process settings, the numerous prices of equipment manufacturer also relative moderate.It is such floating
Select slot that power device is needed to drive rotor operating, the three-phase mixed ore pulp of ore pulp and bubble sucked, then with the bubble that is filled with
Shear-mixed is carried out to complete the mineralization process (re-mineralization system is the prior art) of mineral, coarse granule lean intergrowth in floatation process
It largely is deposited on slot bottom and two slot spacer regions, can only be removed by blowing cleaning, flotation efficiency is lower, blowing cleaning trouble.
Although the equipment of this type has many patents, but the structure type of mainstream is still using Beijing Mine and Metallurgy General Inst
Technology.Beijing Mine and Metallurgy General Inst about traditional flotation cell patent CN87102140, CN87103290,93118179.8,
94100667.0 the technical level for substantially representing traditional flotation cell with 94218361.4.
Second of existing floatation equipment is air flotation column, and flotation column is on flotation function is become by horizontal transition
Lower placement, substantially reduces beneficiation flowsheet, and COLUMN TECHNOLOGY is mainly micro- with 97236893.0 double-cyclone static state of China Mining University
Flotation column and Central South University 01145542.X are steeped for technology representative, and flotation column major diameter is bigger, and the time that foam rises is long, slightly
Particle falls that slot is serious, is unfavorable for the floating of coarse granule lean intergrowth.The third is short column microfoam flotation tank, the skill of such flotation cell
Flotation cell of the art prototype derived from the Venturi tube air-breathing mineralising of Australia's professor's James's invention in 1984, country estate coal washery
00207259.5,02234471.3 patent is microvesicle fast-flotation technology technology development, improves making for such flotation cell
With efficiency, short column flotation cell draw ratio is small, and the time that foam rises is short, is conducive to the floating of coarse granule lean intergrowth.
Three of the above flotation technology and equipment respectively have its superior point, but all cannot fundamentally improve coarse granule lean intergrowth
Rise floating capacity.

Technical solution of the present invention is adaptable, is suitable for the direct flotation process of various oxide ores extensively, has good
Application value.
Since wake flow discharge nozzle is high outside and low outside, the coarse granule lean intergrowth in wake flow be can continue in wake flow discharge nozzle
Interior sinking is further reduced the coarse granule lean intergrowth being discharged with wake flow, so that coarse granule is poor to return in coarse-grained precipitate case
The flotation rate of intergrowth further increases.
Top plate is obliquely installed, so that the ore pulp foam carried secretly in ore pulp will be natural in buoyancy along precipitating roof box 3
Effect is lower to be come back in groove body into middle ore pulp feed inlet, is greatly decreased into the ore pulp foam in wake flow discharge nozzle, is avoided
It wastes raw material, improves flotation rate.
Gravity valve stops the middle ore pulp outside coarse-grained precipitate case to flow into coarse-grained precipitate case through gravity valve.When coarse-grained precipitate case
When the coarse granule lean intergrowth of interior deposition squeezes gravity valve outward, then coarse granule lean intergrowth can be entered by gravity valve
Conical bottom, such gravity valve just naturally form by coarse-grained precipitate case to the unidirectional unlatching outside coarse-grained precipitate case.

Coarse granule lean intergrowth into conical bottom is re-fed into re-mineralization system and carries out circulation mine under the effect of pumping of circulating pump
Change；Coarse granule lean intergrowth is constantly enriched in groove body and conical bottom, and passes through multiple mineralization process, finally forms mine by floating
Groove body is discharged through Foam Flowing Groove after bubble foam；
The coarse granule lean intergrowth in middle ore pulp in coarse-grained precipitate case deposits mutually to separate with middle ore pulp downwards, isolates thick
The middle ore pulp of particle lean intergrowth formed wake flow and along wake flow discharge nozzle be upwardly into Wake control case after be discharged.
