Abstract
The invention discloses a separation method of copper-zinc sulfide minerals, belonging to the technical field of mineral separation. The method takes raw ores of copper-zinc sulfide minerals as raw materials and comprises the following steps: and carrying out flotation separation on the raw ores of the copper-zinc sulfide minerals to obtain copper concentrate minerals or obtain the copper concentrate minerals and zinc concentrate minerals, and adding water-soluble thioglycolate or thioglycolic acid as an inhibitor for the zinc sulfide minerals in the separated minerals in the flotation separation process of the raw ores of the copper-zinc sulfide minerals. Because the water-soluble thioglycolate or thioglycollic acid serving as the inhibitor of the zinc sulfide minerals has the advantages of good selectivity, strong inhibition capability, small dosage, convenient addition and the like, the zinc sulfide minerals can be well inhibited, and a better flotation effect is achieved; meanwhile, the water-soluble thioglycolate or thioglycollic acid has little influence on the environment, does not pollute the environment, well improves the production condition and overcomes the defect that the common medicament has large dosage and damages the environment.
Description
Technical field
The present invention relates to the technique of preparing field, particularly relate to a kind of separation method of copper-zinc sulphide minerals.
Background technology
At present, flotation obtains to copper zinc mixing raw ore copper and zinc bulk concentrate adopts and presses down the floating copper method of zinc and carry out copper zinc when separating, usually adopt flotation separation method, often in the FLOTATION SEPARATION process add conventional medicament, as the inhibitor as zinc sulphide minerals such as zinc sulfate.
The shortcoming of above-mentioned prior art is:
Conventional dose such as zinc sulfate are owing to poor selectivity, and a little less than the inhibition ability, reagent consumption is big, and unit mineral dosing makes with medicament that environment is had destruction up to several kilograms in a large number.Dosing is big, and high concentration is added (being generally 10%), and generally all between 80～90%, the FLOTATION SEPARATION effect is undesirable for the operation separative efficiency.
Summary of the invention
Based on the deficiency that above-mentioned prior art exists, the embodiment of the invention provides a kind of separation method of copper-zinc sulphide minerals, efficient separating copper zinc impregnation ore deposit mineral, and the energy natural decomposition, and low toxicity can reduce the characteristics of environmental pollution.
The objective of the invention is to be achieved through the following technical solutions.
The embodiment of the invention provides a kind of separation method of copper-zinc sulphide minerals, and this method is a raw material with the raw ore of copper-zinc sulphide minerals, comprising:
The raw ore of described copper-zinc sulphide minerals is carried out FLOTATION SEPARATION obtain the copper concentrate mineral, perhaps obtain copper concentrate mineral and zinc concentrate mineral, in raw ore FLOTATION SEPARATION process, add water-soluble thioglycolate salt or TGA as inhibitor to zinc sulphide minerals in institute's separating mineral to described copper-zinc sulphide minerals.
From the technical scheme of the invention described above embodiment as can be seen, because the raw ore at copper-zinc sulphide minerals in the embodiment of the invention is that raw material carries out in the FLOTATION SEPARATION process, adopt water-soluble thioglycolate salt or TGA as inhibitor to the zinc sulphide minerals in institute's separating mineral, because water-soluble thioglycolate salt or TGA have advantages such as selectivity is good, the inhibition ability is strong, consumption is few, interpolation is convenient, not only can well suppress zinc sulphide minerals, reach better flotation effect; Simultaneously,, can not pollute, well improve working condition, overcome the shortcoming that the big environmental pollution of dosing commonly used destroys environment because water-soluble thioglycolate salt or TGA have fewer environmental impacts.And the inhibitor in the embodiment of the invention is that water-soluble solution also has convenient, the safe in utilization advantage of interpolation.For separating, copper-zinc sulphide minerals provides a kind of effective ways easy to use, low in the pollution of the environment.

The separation method process chart of the copper-zinc sulphide minerals that Fig. 1 provides for the embodiment of the invention 1;
The separation method process chart of the copper-zinc sulphide minerals that Fig. 2 provides for the embodiment of the invention 5.
The specific embodiment
The invention provides a kind of separation method of copper-zinc sulphide minerals, mainly be that raw ore with copper-zinc sulphide minerals is a raw material, the raw ore of described copper-zinc sulphide minerals is carried out FLOTATION SEPARATION obtain the copper concentrate mineral, perhaps obtain copper concentrate mineral and zinc concentrate mineral, in raw ore FLOTATION SEPARATION process, add water-soluble thioglycolate salt or TGA as inhibitor to zinc sulphide minerals in institute's separating mineral to described copper-zinc sulphide minerals.
In the said method, raw ore with copper-zinc sulphide minerals is a raw material, the raw ore of described copper-zinc sulphide minerals is carried out FLOTATION SEPARATION obtain the copper concentrate mineral, in each step of floatation process, when needing to press down zinc lifting copper grade, all add water-soluble thioglycolate salt or TGA as inhibitor to zinc sulphide minerals in institute's separating mineral; Perhaps the raw ore with copper-zinc sulphide minerals is a raw material, the raw ore of described copper-zinc sulphide minerals is carried out FLOTATION SEPARATION to be obtained in the process of copper concentrate mineral and zinc concentrate mineral, in each step of floatation process, when needing to press down zinc lifting copper grade, all add water-soluble thioglycolate salt or TGA as inhibitor to zinc sulphide minerals in institute's separating mineral.Wherein, the consumption of inhibitor is that corresponding institute per ton separating mineral adds 10～500g, and the water-soluble thioglycolate salt in the inhibitor can adopt that sodium thioglycolate, TGA potassium, ammonium mercaptoacetate, TGA lithium, TGA are ferrous, in the calcium mercaptoacetate, TGA magnesium any.Can after adding inhibitor, the mineral that separated be carried out stirring in 3～10 minutes, reach better flotation effect so that inhibitor better plays a role.
Water-soluble thioglycolate salt or TGA can be to the zinc vulcanizing mine good restraining in the mineral, because there are two polar groups in thioglycolate salt and TGA molecular structure in the aqueous solution, promptly-SH and-COOH,-SH and zinc sulphide minerals generation chemical reaction absorption mineral surfaces, and-COOH shows hydrophily and forms moisture film, and be suppressed.Make with water-soluble thioglycolate salt or TGA as inhibitor to the zinc sulphide minerals in the floatation process, have advantages such as selectivity is good, the inhibition ability is strong, consumption is few, interpolation is convenient, not only can well suppress zinc sulphide minerals, reach better flotation effect; Simultaneously,, can not pollute, well improve working condition, overcome the shortcoming that the big environmental pollution of dosing commonly used destroys environment because water-soluble thioglycolate salt or TGA have fewer environmental impacts.And the inhibitor in the embodiment of the invention is that water-soluble solution also has convenient, the safe in utilization advantage of interpolation.For separating, copper-zinc sulphide minerals provides a kind of effective ways easy to use, low in the pollution of the environment.
Be described further below in conjunction with the separation method of the drawings and specific embodiments the invention described above.
Embodiment 1
