Description
Technical Field
The invention relates to the technical field of mineral separation, in particular to a method for enriching gold in gold-antimony bulk concentrate.
Background
The mineral composition of the gold-antimony symbiotic ore in the nature is simpler, and the main metal minerals comprise stibnite, natural gold, pyrite, arsenopyrite, stibium bloom and the like; the main nonmetallic minerals include quartz, sericite, calcite, chlorite, clay minerals, etc. The gold mineral in the ore is mainly natural gold, the natural gold is closely related to stibnite and pyrite, and gangue mineral and arsenopyrite are used.
In the process of mineral separation, two most basic procedures are provided: the first is to break and grind the large ore to separate various useful mineral particles from the ore; and the second is sorting, namely sorting the dissociated mineral particles into different products according to the difference of the chemical properties of the materials.
As shown in fig. 1, in the ore grinding process in the existing ore dressing process flow, a first-stage ball mill, a second-stage ball mill and a corresponding classifier are matched to form a two-stage and two-closed-loop process. The ore grinding process is influenced by the capacity of the two-stage ball mill, the proportion of ore particles in the obtained ore pulp to be less than 65% of the size fraction of 0.074mm is insufficient, and the dissociation degree of the pyrite and arsenopyrite monomers is only 70.23%.
In the ore separation process, a single foam flotation process is adopted, the ore pulp to be selected is firstly subjected to partial antimony-first selection process to obtain antimony gold concentrate, and the flotation tailings are subjected to gold-antimony mixed flotation process to obtain gold-antimony mixed concentrate. In the above process, in order to improve the utilization rate of the gold resource, part of non-monomer dissociated minerals (i.e. intergrowths) are usually enriched in the gold-antimony bulk concentrate, so as to reduce the waste of the gold resource, which results in lower gold grade in the obtained gold-antimony bulk concentrate.
In order to solve the problem of low gold grade in the gold-antimony bulk concentrate, the following two methods are generally adopted in the prior art: firstly, returning middling for regrinding; secondly, the concentrate or the rough concentrate is reground and refloated. When middlings are used for returning and regrinding, a large amount of flotation reagents in a gold-antimony mixed flotation process are contained in the middlings, so that when a part of antimony preferential selection processes are performed again after returning and regrinding, the flotation reagents influence part of antimony preferential selection processes (because the flotation reagents used in the part of antimony preferential selection processes are different from the flotation reagents used in the gold-antimony mixed flotation processes), and the quality of antimony gold concentrates is reduced; when the regrinding and refloating process of the concentrate or the rough concentrate is adopted, the phenomenon of over-grinding of the monomer dissociated minerals in the concentrate occurs, and the comprehensive recovery rate of the metal is reduced when the monomer dissociated minerals return to refloating.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for enriching gold in gold-antimony bulk concentrates, which can reduce interference of different flotation reagents and prevent over-grinding of monomer dissociated minerals.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a method for enriching gold in gold-antimony bulk concentrate comprises the following steps:

s2, returning the middlings to perform a regrinding process to dissociate low-grade intergrowths; and combining the secondary concentrate and the concentrate to obtain the high-gold antimony concentrate.

It should be particularly noted that when an element is referred to as being "fixed to," secured to, "connected to or communicated with" another element, it can be directly fixed to, secured to, connected to or communicated with the other element or indirectly fixed to, secured to, connected to or communicated with the other element through other intermediate connecting members. The terms "transverse," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like hereinafter refer to an orientation or positional relationship as shown in the drawings for the purpose of describing the invention only, and do not indicate or imply that the referenced elements must have a particular orientation and, therefore, are not to be considered limiting of the scope of the invention.
Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1, in the ore grinding process in the existing ore dressing process, an ore is firstly fed to a first-stage ball mill, and two-stage and two-closed-loop processes are formed by the first-stage ball mill, a second-stage ball mill and a corresponding classifier to grind the ore; before the ore grinding process, an ore crushing process can be arranged to crush the large minerals so as to be convenient for the subsequent grinding of the minerals.
The ore is ground by a two-stage ball mill to obtain the selected ore pulp, antimony gold concentrate and flotation tailings can be obtained by the selected ore pulp through a part of antimony preferential flotation process, and then the gold-antimony mixed concentrate and the flotation tailings produced by the process can be obtained by the flotation tailings through a gold-antimony mixed flotation process. It should be noted that the processes mentioned in the above two sections all belong to the existing beneficiation processes, so that only the general flow of the processes is briefly described here, and the details of the processes are not described herein again.
As mentioned in the background of the invention section, due to the capacity of the two-stage ball mill, part of non-monomer dissociated minerals (i.e., intergrowths) may exist in the obtained ore slurry to be selected, and in order to avoid the waste of resources, these intergrowths are usually not removed, and finally enter the mixed gold-antimony concentrate after the partial antimony-preferred process and the mixed gold-antimony flotation process, thereby avoiding the waste of resources, but also resulting in a low gold grade in the mixed gold-antimony concentrate.
Aiming at the problem, the invention carries out the table reselection grading regrinding process on the gold-antimony bulk concentrate to enrich the gold in the gold-antimony bulk concentrate and obtain the high-gold-antimony concentrate with higher gold grade. As shown in fig. 2, the method for enriching gold in the mixed gold-antimony concentrate in this embodiment includes the following steps:
s1, carrying out a table concentrator gravity concentration and classification process on gold-antimony bulk concentrates obtained by a gold-antimony bulk flotation process to obtain secondary concentrates enriched with mineralized foam layers, flotation agents and mineral particles with the particle size smaller than 0.02mm, middlings enriched with mineral particles with the low grade and the particle size of 0.2mm-0.074mm, and concentrates enriched with mineral particles with the high grade and the particle size of 0.2mm-0.074mm and mineral particles with the particle size of 0.074 mm-0.02 mm. As shown in fig. 3, the obtained secondary concentrate, middlings and concentrate are collected through three ports in the figure respectively.
It should be noted that the term "enrichment" as used in the present invention means that the components contained in the secondary concentrate, the middlings and the concentrate are mainly distributed in the corresponding ore species; namely, the mineralized foam layer, the flotation reagent and the mineral particles with the particle size less than 0.02mm are mainly distributed in the secondary concentrate, the mineral particles with the low grade and the particle size of 0.2mm-0.074mm are mainly distributed in the middling, the mineral particles with the high grade and the particle size of 0.2mm-0.074mm and the mineral particles with the particle size of 0.074 mm-0.02 mm are mainly distributed in the concentrate, and therefore grading distribution of different components is formed.
In the said secondary concentrate, the mineral particles with the size less than 0.02mm mainly comprise micro-fine monomeric dissociated mineral, the mineral particles with the size of 0.074 mm-0.02 mm in the concentrate mainly comprise medium-sized monomeric dissociated mineral, and the mineral particles with the size of 0.2mm-0.074mm in the middling and the concentrate mainly comprise coarse-sized non-monomeric dissociated mineral (i.e. intergrowth); for the intergrowths, as mentioned above, there is a difference between high and low grade, where the high and low grade mainly refers to the relative amount of gold content in the intergrowths, and different gold content causes different densities, so that the low grade intergrowths are mainly located in middlings under the action of the shaking table, the high grade intergrowths are mainly located in concentrates, and the high grade intergrowths located in concentrates are not required to be returned for regrinding because of high gold content, and the high grade intergrowths are also prevented from being returned for regrinding, while the low grade intergrowths located in middlings are required to be returned for regrinding.
S2, after the secondary concentrate, the middlings and the concentrate are obtained through the S1, the middlings are returned to be subjected to a regrinding process to dissociate the intergrowth with low grade, and then are subjected to refloatation through a part of antimony-preferred process and a gold-antimony mixed flotation process, so that gold in the middlings can be enriched.
Because the singly dissociated minerals are mainly enriched in the secondary concentrate and the concentrate after the table concentrator gravity separation and classification process, the middlings basically do not contain the singly dissociated minerals, the singly dissociated minerals cannot be over-ground, and the comprehensive recovery rate of metals cannot be reduced when the singly dissociated minerals return to refloatation; meanwhile, most of the flotation agents used in the gold-antimony mixed flotation process are enriched in the secondary concentrate, so that the influence of the flotation agents on part of the antimony-preferential flotation process can be reduced when middlings are returned to be reground and refloated, and the quality of the antimony-gold concentrate is improved.
And (3) merging the secondary concentrate and the concentrate obtained in the step (1) to obtain the high-gold antimony concentrate, and dehydrating the high-gold antimony concentrate by a subsequent dehydration process.
Specifically, in this embodiment, the table for performing the table gravity separation and classification process may be an existing 6-S type slurry table, the cross-sectional shape of the table surface is triangular, the gold grade of the gold-antimony bulk concentrate obtained by the gold-antimony bulk flotation process is 37.35g/t, and the antimony grade is 6.04%. After the table concentrator gravity separation and classification process is carried out, the yield of the obtained secondary concentrate is 25.2 percent, wherein the gold grade is 40.23g/t, and the antimony grade is 10.23 percent; the yield of the concentrate is 33.4 percent, wherein the gold grade is 68.52g/t, and the antimony grade is 6.32 percent; the yield of middlings is 41.4 percent, wherein the gold grade is 10.43g/t, and the antimony grade is 3.25 percent; and (3) merging the secondary concentrate and the concentrate to obtain the high-gold antimony concentrate, wherein the gold grade is 56.35g/t, and the antimony grade is 8%. Therefore, the gold grade of the high-gold antimony concentrate obtained by the process is enriched by 1.5 times.
It should be noted that most of the mineral separation processes in the prior art form mature and relatively fixed process flows, and in the existing process flows, the table gravity separation and classification process is generally used for processing ores which are not processed by a flotation process, and the ore forms are all granular; in the invention, a table concentrator gravity separation and classification process is creatively introduced after the flotation process, high-grade high-gold antimony concentrate can be obtained through the table concentrator gravity separation and classification process, and meanwhile, middlings basically do not contain monomer dissociated minerals and flotation agents used in the gold antimony mixed flotation process, so that the phenomenon of over grinding of the monomer dissociated minerals during regrinding can be avoided, the flotation agents are prevented from being mixed into part of the antimony preferential flotation process during refloating, and the quality of the antimony gold concentrate is improved.
In the embodiment, because the treated mineral is the mineral treated by the flotation process, part of the mineral exists in the form of foam, and the monomer dissociated mineral or the non-monomer dissociated mineral has multiple size fractions and different grades; in order to better carry out gravity concentration and grading on minerals, the stroke of the shaking table in the gravity concentration and grading process of the shaking table is 20-25mm, and the stroke frequency is 260-280 times/min; specifically, in this embodiment, the stroke of the shaking table in the gravity concentration and classification process of the shaking table is 25mm, and the stroke frequency is 260 times/min.
The invention sets the shaking table as high stroke and low stroke frequency, which can improve the longitudinal movement speed of coarse-particle non-monomer dissociated minerals and medium-fine particle monomer minerals and rapidly separate the coarse-particle non-monomer dissociated minerals from mineralized foam layer and fine-particle minerals. It should be noted that the mixed gold-antimony concentrate processed in this embodiment belongs to high-density and fine-grained minerals, and when this type of minerals is subjected to a table gravity separation and classification process, the table is usually set to be low-stroke and high-frequency, but in actual use, it is found that when the above setting is adopted, the separation effect of mineralized foam layer and fine-grained minerals from other minerals is not good, and when the high-stroke and low-frequency setting opposite to the conventional process is adopted, a good separation effect can be achieved. For the other two settings, when a high stroke and a high frequency are selected, micro-fine particle minerals can be mixed into a middling product, and coarse particle low-grade minerals can also be mixed into a concentrate product, so that the middling grade is higher and the concentrate grade is lower; when a low stroke and a low stroke frequency are selected, the transverse movement speed of most minerals is too low, and the minerals are difficult to separate from a mineralized foam layer and micro-fine particle minerals, so that a good separation effect cannot be achieved by adopting the two settings.
In this embodiment, the mineralized foam layer floats on the water surface and is subjected to a smaller force by the driving device of the shaking table, and therefore, the longitudinal gradient of the bed surface of the shaking table in the gravity separation and classification process of the shaking table is 0 degree, so that the mineralized foam layer is prevented from entering the middling area due to the influence of gravity. It should be noted that in the present embodiment, the longitudinal direction is the longitudinal direction of the rocking bed surface and the transverse direction is the width direction of the rocking bed surface, i.e. the longitudinal and transverse directions are indicated in FIG. 3.
In the gravity separation and classification process of the shaking table, the ore feeding amount is 0.2 to 0.3t/h, the ore feeding concentration is 10 to 15 percent, and the transverse flushing amount is 2 to 4m 3 H; specifically, in this embodiment, the feeding amount is 1t/h, and the fed gold-antimony bulk concentrate is pumped to the table feeding barrel by the centrifugal pump and then uniformly distributed to four table surfaces of the table, i.e., the feeding amount of each table is 0.25t/h, in this embodiment, the feeding concentration is 10%, and the lateral flushing amount is 4m 3 H is used as the reference value. According to the embodiment, the ore feeding water quantity is increased, the ore feeding concentration is adjusted to be lower, the transverse movement speed of the mineralized foam layer and the micro-fine particle minerals can be accelerated, and the clear water is better utilized to clean the mineral surface agent and dilute the agent concentration.
In the table surface reselection grading process, the transverse gradient of the table surface is 0.5-1 degree; specifically, in this embodiment, the transverse slope of the bed surface is 1 °, and the transverse slope of the bed surface is actually adjusted and regulated by matching with the transverse flushing water amount, because the transverse flushing water amount is relatively large in this embodiment, in order to avoid the excessively high transverse movement speed of the low-grade middling, in this embodiment, the lower transverse slope of the bed surface is set so that the middling has a proper transverse movement speed, so that the middling can be separated from other minerals and is not easily mixed together.
