Problems solved by technology

(2) The content of heavy metal ions and COD in the tail water exceeds the standard
[0011] Though above-mentioned these patents all relate to the flotation depressant of iron sulfide or zinc sulfide, and what have also relate to the method that adopts non-lime to carry out flotation, but by reading these patents, it can be known that these patents are not related to the present invention. The problem to be solved has nothing to do with it, and the disclosed technical scheme is more complicated than the flotation treatment scheme proposed by the present invention, and the materials used are also more, which is difficult to prepare and produce, so it still needs to be further improved

Embodiment 1

[0037] This example is an example of medicament preparation: the following five substances are used as raw materials for the inhibitor:

[0038]

[0039] The ratio of the above-mentioned raw materials is: when A:B:C:D:E =0.3:0.2:0.2:0.2:0.1, it is formulated according to the above-mentioned method to obtain a qualified compound inhibitor.

Embodiment 2

[0041] This example is a sorting application example. An ore containing zinc sulfide and iron sulfide minerals contains 4.95% zinc and 10.79% sulfur. The inhibitor used in this example is used as the inhibitor of iron sulfide minerals to flotation zinc sulfide minerals. The amount of inhibitor used in this example is 300g / t, and the amount of lime is zero. Four steps are carried out according to the process structure of one roughing, one sweeping and one beneficiation. The average sorting index obtained in the closed-circuit process test of one cycle is shown in Table 1.

[0042]

Embodiment 3

[0044] This example is an example of medicament preparation: the inhibitor has adopted the following four substances as raw materials:

[0045]

[0046] The ratio of the above-mentioned raw materials is: when A:B:C:D =0.2:0.3:0.2:0.3, it is formulated according to the above-mentioned method to obtain a qualified compound inhibitor.

Abstract

The invention discloses an inhibitor for inhibiting flotation of zinc sulfide ore from iron sulfide ore and preparation and use methods thereof. The inhibitor comprises at least one or more of non-metal acid salts and oligomers thereof, monothio non-metal acid salts and the oligomers thereof, dithio non-metal acid salts and the oligomers thereof, trithio non-metal acid salts and the oligomers thereof and tetrathia non-metal acid salts and the oligomers thereof; and the inhibitor for inhibiting the flotation of the zinc sulfide ore from the iron sulfide ore is formed by one or more of the non-metal acid salts and the oligomers thereof, the monothio non-metal acid salts and the oligomers thereof, the dithio non-metal acid salts and the oligomers thereof, the trithio non-metal acid salts andthe oligomers thereof and the tetrathia non-metal acid salts and the oligomers thereof. Raw materials are selected according to the composition of ores containing minerals of zinc sulfide and iron sulfide, one or two or more of the five materials of the inhibitor are selected to be mixed and stirred evenly with the raw materials, and then an aqueous solution inhibitor is formed by adding water tothe mixture and mixing and stirring; and the inhibitor is added to the roughing, scavenging, and carefully selecting process of the flotation to inhibit the flotation of the zinc sulfide ore from theiron sulfide ore.

Description

technical field [0001] The invention relates to a flotation aid and its preparation and use method, in particular to an inhibitor for inhibiting iron sulfide ore flotation zinc sulfide ore and its preparation and use method. The inhibitor and its preparation and use method can realize the flotation separation of zinc sulfide and iron sulfide ore under natural pH conditions, and belong to the field of mineral processing flotation reagents. Background technique [0002] There are two commonly used flotation separation methods for zinc sulfide minerals and iron sulfide minerals at home and abroad. One is the priority flotation process in accordance with the operation sequence of flotation zinc sulfide minerals and then flotation iron sulfide minerals. In the operation of flotation zinc sulfide minerals, it is necessary to add lime to adjust the pH value of the slurry to be above 12 to suppress iron sulfide minerals; in the next operation of flotation iron sulfide minerals, it i...
