Problems solved by technology

[0006] (2) The content of heavy metal ions and COD in the tail water exceeds the standard
[0012] 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

Abstract

The invention discloses monosulfo-nonmetallic acid salt and a low polymer floating inhibitor thereof. The inhibitor is composed of monosulfo-nonmetallic acid salt and low polymer thereof, and inhibitsiron sulfide ores to float zinc sulfide ores under a natural pH condition. The monosulfo-nonmetallic acid salt and low polymer thereof comprise two molecular structural forms which have structural characteristics of monosulfo-nonmetallic acid salt and low polymer; and the monosulfo-nonmetallic acid salt is nonmetallic oxysalt. With the adoption of the inhibitor disclosed by the invention, a lightinhibiting method of not adding lime can be adopted in a floating process to inhibit iron sulfide ores to float zinc sulfide ores; and the pH value of ore pulp obtained by zinc sulfide ore floating operation is obviously different from the pH value (12 or higher) of ore pulp obtained by claimed zinc sulfide ore floating operation adopting lime as iron sulfide ores, and is within a neutral range of 6-9.

Description

Technical field: [0001] The invention relates to an inhibitor of a flotation clean production method and its preparation and use method, in particular to an inhibitor for inhibiting iron sulfide ore flotation zinc sulfide ore under natural pH conditions and its preparation and use method. The invention relates to an inhibitor for inhibiting iron sulfide ore flotation zinc sulfide ore under natural pH conditions and a preparation method thereof, belonging 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 ...
