Description
Technical field
The present invention relates to technical field of mineral processing more particularly to it is a kind of improve the selected copper grade of copper method and device,
Suitable for ore dressing industry application.
Background technique
Too long in flow is avoided in order to reach, while saving space-efficient purpose in mine flotation process both at home and abroad at present,
Rough concentrate often by pipeline is directly entered selected operation and because of production technology needs, must also add in coarse-fine ore pulp various
Regulator, to produce qualified concentrate containing.But the generally existing following deficiency of traditional handicraft: first is that regulator is added to coarse-fine ore pulp
In, it begins to carry out selected operation, substantially without action time, medicament effectiveness does not also give full play to regulator, both causes medicine
The waste of agent, and make adjustment effect poor；Second is that concentrate grade is low only through primary cleaning, and selected operation liquid level be easy by
The influence of roughing operation, when the fluctuation of rough concentrate yield, selected operation liquid level fluctuates therewith, controls unstable.Due in ore dressing
In factory's design process, site technique process is often set according to ore beneficiation feasibility research report.So site technique process one
Denier determines, is difficult to be modified again, even if can achieve the purpose that change process flow by technological transformation, it is also desirable to expend huge expense
With.Therefore, most dressing plant's meetings are since it is desired that putting into enormous expenditure and abandoning carrying out technological transformation to original process flow.Together
Sample, with the progress of ore extraction, the certain properties of ore may change, so as to cause initial design process flow without
Method meets production requirement.In addition, with the development of economy, requiring also increase accordingly to dressing plant's product quality, existing stream
Journey design is unable to reach higher requirement: such as in terms of improving concentrate grade, most common method is " to increase selected job step
Number ", i.e., scene needs to place more flotation devices, achievees the purpose that increase selected operation number of segment, however the ore dressing of the overwhelming majority
Factory is very compact since device is laid out, and there is no extra spaces to put additional increase flotation device.
To solve the above problems, Chinese patent discloses some solve the problems, such as more above-mentioned technical solution successively:
Chinese patent CN1895788 discloses a kind of " the ore-dressing technique method that concentrate grade and the rate of recovery can be improved ", should
Method is to increase one of Ultrafine Grinding i.e. bed of material rolling-type disintegrating apparatus, grain in classical three section of one closed circuit ore crushing technique process
In -5mm or so, the technique for realizing much broken and lessmill can improve the degree of dissociation of grinding efficiency and ore, but shortcoming meeting for degree control
Muck operation and maintenance cost are greatly increased, while influencing muck treating capacity.
Chinese patent CN103801460A discloses " a kind of floatation process of low-grade copper ": using the novel collecting of cupro-nickel
Agent and the process optimization for taking roughing three times, are conducive to the raising of copper concentrate copper grade and the rate of recovery, and shortcoming is using work
Property charcoal carry out physics reagent removal and lime and make nickel mineral inhibitor carrying out copper moulding, mutually containing serious.
Chinese patent CN101428251 discloses a kind of " method of selected section of raising molybdenum concentrate grade ": by changing essence
The some processes process of selections improves selected III, selected IV ore pulp beneficiation enrichment ratio, extends flotation time, for smart V flotation bubble
The raising of foam grade is laid a good foundation, to achieve the purpose that improve final concentrate grade, is disadvantageous in that undeclared essence
IV tailing and selected V tailing are selected, returns to selected III flotation column agitator and selected III flotation froth respectively, if is influenced selected
III flotation and the classification of selected III foam and regrinding process, control condition does not also specify and concentrate grade increase rate is little.
